Yes, DHT11 should work as well, but Im not sure how well it be. #define WIFI_PASSWORD "YOUR_WIFI_PASSWORD". I discovered that running the update all command on the WSPHome web UI fixes it. What I have now is the sensors are connected to the ESP home. Instead of that I settled for a less documented, but way more powerful lambdas, that allow you to add C++ code just into your yaml. Just a fun read. When were just getting the water ready we need more regular feedback from the UI, and for the rest of the day it can just do some rare checks waiting for the water to appear in the bath. Go to Devices section. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'peyanski_com-medrectangle-4','ezslot_4',104,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-peyanski_com-medrectangle-4-0')}; As I said this USB adapter is optional as you can just plug the sensor in any USB port that you have available. You dont need to include it in the publish topic. Click + button and create a device with the name ESP8266 Demo Device. The first idea was to just order a dumb water thermometer. Your email address will not be published. Wait until you see some temperature and humidity readings or something like this below: Press the c button on your keyboard and start typing, Search for ESPHome integration within the list with discovered integrations and click on the, On the next screen you can see your Temperature and Humidity readings and you can add this as a card in your Home Assistant Dashboard by just clicking on the, l Broker Wemos D1 Mini mit Sr04 & AM2301 mqtt . @home_assistant @shelly_IoT. That is great Christoph! Necromancer's notes In order to perform troubleshooting, you should assemble your hardware according to the Programming/flashing schema. This makes sense as ESPHome is about 5000% easier to configure compared to SensESP especially given the recent updates on its deployment features. Everything these sensors capture is forwarded every 10 seconds to an MQTT server (a kind of telephone exchange for IoT applications), which communicates it to a small application that I wrote in node-red. Yeah I hate converting types in ESPHome. ESP8266 offers a complete and self-contained Wi-Fi networking solution. This was the part where the magic began. I know this on_value syntax is wrong but could someone suggest what the correct way of doing this is? I left the device running in bathroom when I was away from home for about a week or so. Then connect USB-TTL adapter with PC and select port of the USB-TTL adapter in Arduino IDE. However in November I had to pause that for a few weeks. DIY some useful smart sensors is pretty addictive, dont you think? Installation guides - Learn how to setup ThingsBoard on various available operating systems. I want to thank you as well, because of sharing this! This allows updating wherever possible and gives easy access to my various devices logs and status. The operating temperature of the DHT22 is from -40 to +125 degrees Celsius so in theory it should be fine outside if you waterproof it well. could someone suggest what the correct way of doing this is? Thats a replacement for our will messages we commented out earlier. Wanted to share my enclosure. Is that correct? In Home Assistant, you also have an ESPHome community add-on. If you are using Live Demo instance all entities are pre-configured for your demo account. After, open Dashboards section then locate and open ESP8266 DHT22: Temperature & Humidity Demo Dashboard. I thought it would be a good idea to report that the battery died by explicitly marking all entries as Unavaliable in the UI. I picked 7 minute intervals when theres no water in the bath and 1 minute when there is water. I will try my best to show you everything needed for the DIY Temperature sensor for Home Assistant: On top, if you have access to a 3D printer I will also show some enclosures that can make the sensor looks better. Click on install and wait for a minute to download the board. If its 4 degrees either way most likely theres water. Paste the following URL to the Additional board managers URL: http://arduino.esp8266.com/stable/package_esp8266com_index.json. The Swiss pocket knife for boat automation is a system called SignalK, which totally a totally amazing tool. That would do just fine. The USB port where your device is connected will be auto detected and you should only click on it, example: If everything is fine, a terminal will appear with a lot of text and multiple text based progress bars. These topics sends data as 20.4 or 50% or 80%. When you hit that button, our Google Nest Hub started playing Christmas music, and the lights turned on. Not sure why it didnt work, its the same as the documented example. This is what I made with my very first ESP8266 board: Many wires, a motion sensor, a light sensor, a microphone, a temperature and humidity sensor, a screen, and a laser beam. This is useful because it allows you to keep your sensors where they are and still make configuration changes. Try it out and you can do the same. According to your excellent tutorial I installed a BME280 Sensor (temperature, humidity, pressure) on a supervised installation on a RPI4, also following your advice. Just connect Vdd, Data, and Ground (pin 4) as per this diagram: https://cdn-shop.adafruit.com/datasheets/Digital+humidity+and+temperature+sensor+AM2302.pdf. Lets just poll the difference of air and water temperature. Connect USB-TTL adapter with PC. Inside my server cabinet, there is an ESP8266 with a DHT11 temperature and humidity sensor connected to PIN D2. Also, on the D1 Mini I will attach the Temperature & Humidity sensor. In the menu tools, click on the menu option Board: Most likely Arduino UNO. For around $5 to $6 US dollars and several minutes I managed to DIY temperature sensor for Home Assistant and with that to make my Home even Smarter. I started back in summer when it was hot as hell and went all the way through to November. But once deep and everything else was working perfectly it was the time to make it run autimatically every boot. But why order when you have all the parts in stock and can just build one? Click Copy Device ID in device details to copy your device id to the clipboard. Windows users should follow this guide. Paste the following lines at the very bottom of the configuration: You may wish to change both names (Living Room Temperature & Living Room Humidity) to whatever is suitable for you. Little did I know theres already a project that does everything I did and more: ESPHome. Click on the 1 device link. You may use username [emailprotected] and password tenant. One for current session, one for last session. {Outside Illuminance:0)} (Please ignore the mixing of temperature, pressure, illuminance etc - thats just me messing around with different BMP280 sensor values and clearly not relevant to the issue), For my application, that doesnt work and I need it to read. I am planning to use some of the humidity and battery values also. The story is simple. You can access this dashboard by logging in as a tenant administrator. Nowadays, DIY temperature sensor for Home Assistant can be very easy and cheap especially, if you have a complete guide like this one that will show you all the steps. The hardware for this project was pretty dumb. Welcome to the club! My circuit has a voltage divider, so its only a matter of finding out what we need to do to enter deep sleep forever when the voltage drops below a threshold. After the first flash via USB, your ESPHome can update OTA (over-the-air over WiFi). This can be set in the bottom of terminal screen. To reset that state we need something like his at the very start of the script (or an uncommented birth_message): Not an investment strategy a medical advice. Last session data is only updated when we enable the Save session switch in Home Assistant UI. The only thing that is missing is a 3D printed enclosure. I want to setup a multizone heating system for my home. By continuing to browse this site, you agree the use of cookies, in accordance with our, thingsboardServer - ThingsBoard HOST/IP address that is accessible within your wifi network. If you dont want to use json you have to do this: Thanks, @tom_l and I did try that but I then end up with: And couldnt find a way to cast a float to a string. Set up MQTT server IP adress instead of DNS name. Open the serial monitor (by pressing CTRL-Shift-M or from the menu Tools). The ESP32 that i used have a port sink current greater than the current needed to the DHT11 make a mesurement, so i let the DHT VCC pin on VCC and the GND i attach to a GPIO that keeps pulled up when deep sleeping.
Yet I didnt have a reason to get it done. I will try to show you everything and as usual, I will add Shelly Motion 2 in Home Assistant Read more, I always wanted to have a local smart speaker that can announce Text-to-Speech messages configured in my Home Assistant automations. And something tells me those cells dont even have a BMS making the pretty much unsafe to use. After installation (pip3 install esphome), you can quickly start a new project via the wizard (esphome serverkast.yaml wizard), and after answering some questions, the wizard writes out a YAML file containing the minimum configuration: When you flash this on your ESP (esphome run serverkast.yaml), your ESP will reboot, connect to your WiFi network and appear in Home Assistant. Powered by Discourse, best viewed with JavaScript enabled. When youre just getting the water ready youll need a faster poll interval. But for this project it would be most optimal to just add a normal 18650 cell with a proper BMS (looks like these batteries have just no BMS whatever) and implement low voltage cut-off with setting the state as unavailable in Home Assistant. Another question. During the Christmas period, I connected an ESP with some LEDs (I didnt know WLED at that time) and a button. xiaomitemperature/sensors/sensor/sensor_2_humidity/state 400 shady Chinese mAh ended up in about 9 days of uptime (25 november to 3rd of december. Now we can add the board ESP8266 using the board manager. In the configuration file, this becomes (beneath ota:): (Because DHT11 temperature sensors are cheap but not precisely accurate, a small calibration occurs: 24 degrees is adjusted to 23.5.). Go to Devices section and locate ESP8266 Demo Device, open device details and switch to Latest telemetry tab. Esphome hass 2 ways to send data to Home Assistant: API & MQTT. When you are ready, click on the. Youll get tired of this very quickly. It seems that the manual call to update() on a sensor object may update the value immediately or may just start the asynchronous update. Hang an e-paper display on it? Data is visualized using built-in customizable dashboard. Designed to be completed in 15-30 minutes. Thanks to ESP Muse Luxe this is now possible, but it needs some configurations upfront. Then connect the middle output of the DHT22 labeled, Add the official ESPHome add-on repository by click on, While in Home Assistant, press the c button on your keyboard and start typing, Wait few seconds for the ESPHome to start and then click on the, You should see similar screen as above. Ideally that would become a habit. Advanced features - Learn about advanced ThingsBoard features. Here is how my whole D1 Mini and DHT22 configuration looks like at the end: I have a quick challenge for you! Learn how your comment data is processed. This unit sends the data over MQTT to the Homey-MQTT broker. Whats the catch here? I am going to make it soon! So, buckle your belts as we are starting with the needed parts for this DIY Temperature & Humidity sensor. This way I could debug it using OTA updates, instead of using uart. At this point we move on to deep sleep. Development of solutions by the ThingsBoard team, Energy monitoring and efficiency analysis, Remote soil, products and equipment monitoring, Collection, analysis and visualization of data from meters, Monitor and analyze indoor and outdoor environments, Increase productivity and optimize resource consumption, Water consumption analysis and fraud detection, Control quality of food storage, indoor environment and safety. Its important that state_topic and command_topic are set to the same topic and have the retain flag set. Enjoy and welcome to the club! That chip can be programmed in the same way as an Arduino but has built-in WiFi and the necessary libraries to enable IoT applications. It wants a string but we gave it a number. So the main usage now is pretty dumb: sleep for as long as possible, wake up, get and send the sensor data, and got to sleep as fast as possible. Is there a way to actually run something like this on batteries? And here is what I managed to find and print on my Ender 3 v2 3D printer (my article about the printer): If you manage to find other good ones, please share them in the comments section below. These days you can waste a lot of money on smart appliances. Files are here https://www.thingiverse.com/thing:5403775, Thats very nice and useful tutorial, actually really similar to https://www.pieterbrinkman.com/2021/02/03/build-a-cheap-air-quality-meter-using-esphome-home-assistant-and-a-particulate-matter-sensor/. Time to fix that and add yet another battery optimization manual for ESP8266 to the internets. I decided to try cold water immersion practice and make it a habbit.Yep, not the cold showers, but true hardcore CWI. If you dont have Home Assistant yet, check this article of mine where Im explaining what are your options LINK. The video below demonstrates the final result of this tutorial. If we do some simple math well get those 70mA of power consumption folks reported back in 2015 or so when those devices just started to appear on the market. Be careful if you make something like this, and you have kids. You can do this in the Home Assistant interface but also in the configuration file itself: The latter has the advantage that your automation works even when Home Assistant is not accessible and is especially recommended for simple automation that does not require other devices in your network. Most of them were already disposed, but I had two still around. After checking out a few leads, esphome documentation and my own thoughts, I ended up with the following: Resulting config part looked something like that: This is very useful. I partially populated a board from a different project, keeping only the bare minimum: esp8266 module, 3.3 Volts DC-DC, DHT11 desoldered from a different board, but still functional and most importantly a ds18b20 sensor on a long wire. Feel free to secure this channel existence by using any of the supported methods in my Website support section. So I quickly calculated the number of sensors I needed to poll and added a global variable. Open ThingsBoard Web UI (http://localhost:8080) in browser and login as tenant administrator. And whats the big reason? Too big, judging by the looks, but who cares? Finally, place a resistor (between 4.7K and 10K) between pin number 1 and 2 of the DHT sensor. This way we can set the device state as Unavailable in Home Assistant that will tell us that the battery is now dead. Find and install the following libraries: Note that this tutorial was tested with the following versions of the libraries: Download and open esp8266-dht-mqtt.ino sketch. This trick worked like a charm and I moved on to other hacks. The data is sent over MQTT and received by Homey broker. The DHT22 sensor is connected to ESP8266. Please save this device token. Type in the search bar the 3 letters ESP. The script will do all the required magic and run once at boot. By subscribing you agree to receive newsletters from ThingsBoard, Inc. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. I hadnt thought about basically turning off the ESPHome loop and coding everything in a script. Specify demo.thingsboard.io if you are using. If all is configured correctly you should be able to see latest values of temperature and humidity in the table. We use cookies to improve user experience. My problem is how to get the temperature data into the virtual thermostat as sensor value. Before you continue further it is a good idea to check in the ESPHome dashboard if your DIY Temperature Sensor for Home Assistant is actually online. I used my simple esphome configurtion template to connect to Home Assistant via API, pumped the values once every minute. To do this, the ESPHome sends an event to Home Assistant: Home Assistant sets the Nests volume to 75%, selects a random Christmas song, lights on, and turns on the Philips Hues Cozy scene. Not bad, but how much time to we need to connect to a WiFi hotspot, get all the data and send it? But what is good and bad about it? I managed to sort it out - it was actually quite simple. I guessed that I should use mqtt.publish (no JSON) instead but again struggling to find the correct syntax as this doesnt work and gives the above result ("id(outside_pressure).state). Powered by Discourse, best viewed with JavaScript enabled. Well later use this stuff for powersaving. After starting Arduino IDE, open the preferences from the file menu. Its very, very close but just not close enough so if you could make some further suggestions I would really appreciate it for all the boaters out there. Now, lets finish this by adding the D1 mini and DHT22 based smart Temperature & Humidity sensor in Home Assistant. Having said that, Why are you doing this? I added to my (already starting to look scary) check_stuff script even more lambdas.
The process requires you to have another computer, on which you have to perform several steps to Read more, Kiril Peyanski After reflashing (via USB or over WiFi), these sensors appear in Home Assistant: In Home Assistant, the data from these sensors can now be used to perform automations or to create beautiful graphs using, for example, InfluxDB: The great thing about ESPHome is that everything you can think of works out of the box. If its more than 4 degrees most likely theres some water, right?. ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems. The LiIon cells were not perfect. Thats magic @tom_l - compiles now and will investigate what gets to my MQTT server later. Or make such smart devices yourself. https://physoc.onlinelibrary.wiley.com/doi/full/10.1113/EP086283, https://pubmed.ncbi.nlm.nih.gov/30896355/. In other words Ive ended up with yet another global variable and another lambda. I highly recommend MQTT explorer for exploring the broker contents: An all-round MQTT client that provides a structured topic overview, Thanks @tom_l and I use MQTT Explore already. Thank you for your interest in ThingsBoard!Have a great day! Note You need to edit following constants and variables in the sketch: Connect USB-TTL adapter to PC and select the corresponding port in Arduino IDE. Shelly Motion 2 was just released, but what is good and what is bad about it? Required fields are marked *. Given that SignalK acts as an MQTT broker and ESPHome can publish MQTT events, it seems to make total sense to try to connect them and let ESPHome publish data to SignalK. This way we will end up with nice charts documenting the process of becoming a Yeti ;). I really wanted my feelings against hard sensor data. If we have ON set, we disable sleep and wait for a new firmware to be uploaded. unfortunately, Home Assistant dosnt plot dates on the chart). Prepare your hardware according to the Programming/flashing schema. Note that this tutorial was tested with the esp8266 by ESP8266 Community version 2.3.0. Though, I didnt find a way to actually use it. Lets see how to install the ESPHome add-on. This way were working for 10 seconds, sleeping for 10 minutes and so on. Save my name, email, and website in this browser for the next time I comment. Open Arduino IDE and go to Sketch -> Include Library -> Manage Libraries. I encountered a couple of minor issues that others might experience. Simple! The easiest way is to use Live Demo server. -, Optimizing ESP8266/ESPHOME for battery power (and making an ice bath thermometer as well), Distributing python apps for windows (and dealing with the pain), Useful scripts: Compiling big projects remotely, Ditched DHCP in favor of a static IP (Faster IP setup, less traffic more power saving). 3.3V power source (for example 2 AA batteries). Its been a long while I wanted to check for how long can an esp8266 with esphome last on a battery supply. - Thanks and enjoy!
Many boaters run ESP8266 sensors (to check their battery banks, bildges etc) and their platform of choice for them is something called SensESP. I use mine to measure the temp on the exhaust pipe on my electric dryer. I found it in the Integration section after which it looks also different. Browse other samples or explore guides related to main ThingsBoard features: Dont hesitate to star ThingsBoard on github to help us spread the word. Finally, open ThingsBoard Web UI.
ESP8266 push data to ThingsBoard server via MQTT protocol by using PubSubClient library for Arduino. If you reach this point and you managed to install ESPHome on your future Smart Temperature & Humidity sensor let me know in the comments by just type #THowned. Use: in case of local ThingsBoard installation. That doesnt make a big difference since the voltage is falling really fast anyways. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[250,250],'peyanski_com-box-4','ezslot_3',126,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-peyanski_com-box-4-0')};All components will cost you around $5 to $6 US Dollars (if you already have microUSB cable) and you can buy them using the AliExpress affiliate links below: At the end of the day, it is not so important from where you will get the needed parts, but how you will connect them and how you will configure them. The exact model of the sensor that Im going to use is AM2302 DHT22 and it is looking like this: if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[580,400],'peyanski_com-medrectangle-3','ezslot_6',125,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-peyanski_com-medrectangle-3-0')};I will also need 3 female-to-female jumper wires, also known as Dupont wires. I am planning to use some of the humidity and battery values also. Paste your device id to some place, this value will be used in further steps. Download the dashboard file using this link. NEW ARTICLE https://peyanski.com/shelly-motion-2-review-home-assistant-integration/ Locate and click on esp8266 by ESP8266 Community. Linux users that have docker installed should execute the following commands: These commands install ThingsBoard and load demo data and accounts. Learn how your comment data is processed.
Create a website or blog at WordPress.com. ThingsBoard UI will be available using the URL: http://localhost:8080. // Check if any reads failed and exit early (to try again). Getting started guides - These guides provide quick overview of main ThingsBoard features. For example, the temp changed from 78 F to 12 F, so not a matter of the wrong units. I also added a 18650 cell holder and plugged a 18650 LiIon Battery there. Not a HA question. But my only concern is that it has to run on a socket, thats really not convenient. I always copy my configuration files here after flashing via USB. The application that is running on ESP8266 is written using Arduino SDK which is quite simple and easy to understand. You will need to have ThingsBoard server up and running. The first thing that you will need Is an ESP8266 device, and Im going to use a Wemos D1 Mini. The recommended solution looked somewhat like this: So we monitor an MQTT topic for $devicename/ota, if we see ON there, we set a magic variable that blocks sleeping. Humidity is another metric we get for free from DHT11. Check below ESP Home is not in the Configuration section anymore. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[336,280],'peyanski_com-leader-2','ezslot_10',111,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-peyanski_com-leader-2-0')};Where TH stands for Temperature and Humidity. Or create your own IR remote control? Wow, so clever That is why I love all of these stuff. And that meant the only thing: I had to start over again. This site uses Akismet to reduce spam. But I can not get it to work. The weather gradually lowered the water temperature for me from ah, cool and nice to Awh shit this is cold!11.
Water presence can be determined using water/air temperature difference. Of course, this does absolutely nothing. It will be referred to later as $ACCESS_TOKEN. As example, one sensor sends the following topic: xiaomitemperature/sensors/sensor/sensor_2_temperature/state Im very happy that you did it. Here are the steps to connect D1 Mini and DHT22 Sensor: if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'peyanski_com-large-leaderboard-2','ezslot_7',109,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-peyanski_com-large-leaderboard-2-0')};This is how everything looks like at the end: Next step is to upload ESPHome software on the D1 Mini device. Thanks for this. The temperature difference should theoretically match how cold it feels. As I said in my previous article about our staircase with 600 LEDs, Espressif ESP boards are ideal for when you want to make things that connect to the Internet: Luckily other development boards are very good at that. Copy it while you have the yaml open so you can paste it in. When the dryer completes a cycle, it shuts off & the temperature at the vent cools down enough for me to trigger a notification to my phone & my wifes computer to remind us to take the clothes out. This now looks totally different in the latest version of Home Assistant. Read more, Until now, it was not possible to install Home Assistant OS on Raspberry Pi 4 over the network. In the menu Tools Board Most likely Arduino UNO three new boards are added.
