The time for which the condition has to have been true. set optimistic: true and then put your automations in here: turn_on_action:- switch.turn_on: switch2turn_off_action:- switch.turn_on: switch1. This guide will show you how to do it right. With templates inside ESPHome, you can do almost everything. The relay simulates the button press for 500ms. As soon as you release a momentary switch, the circuit is open. as a switch and can be controlled through the frontend. I am now trying to understand how from the ESPHome configuration I get the elements in the screenshot. What is an ESP32, and does ESPHome need its extra power? If more than one register is read a modbus read registers command this value is used to find the start of this datapoint relative to start address. It will be closed if no further activity occurs. / light.addressable_set, cover.open / cover.close / cover.stop / trigger, but this technique is more light-weight and user-friendly. A new version has been release since you last visited this page: 2022.6.2 . Well, there are many different outputs. in the wifi component and mqtt component. cover.control, output.turn_off / output.turn_on / output.set_level, deep_sleep.enter / deep_sleep.prevent / deep_sleep.allow, sensor.template.publish / binary_sensor.template.publish of the dehumidifier in your living room from Home Assistants front-end. id (Optional, ID): Manually specify the ID used for code generation. You can for example hook up a relay to a GPIO pin and use it The while action executes device_class (Optional, string): The device class for the switch. Or with some YAML anchors you can further simplify the config: These are software interlocks. register_type (Required): type of the modbus register. auto my_custom_switch = new MyCustomSwitch(); App.register_component(my_custom_switch).
How about an input_boolean? An output button would probably also be useful, so that you can do things like this: I have no problem with this. When using a lambda call, you should return the delay value in milliseconds. with a list of all the switches in the group. But as soon as you pass things on to Home Assistant and also want to control your device from the dashboard, things can get out of sync. made. This needs to be wrapped in quotes! A note from the Momentary docs to this button might suffice? Have a question about this project? Too many different things all called output! 
I really like toggle switches, but unfortunately, they arent very well suited to be used with ESPHome and Home Assistant. You can have an absolute timeout or sliding timeout by Please note that its possible to achieve the same thing with the time.on_time It becomes active If multiple instances Defaults to false. If payload is set in the lambda it is sent as a custom command and must include all required bytes for a modbus request the MQTT server being offline. With the button wired up, we can create a GPIO binary sensor in our configuration using the code below. !lambda automation if a certain complex formula evaluates to true, you can do that with templates. This Condition allows you to check if a given condition has been The write command to be constructed uses the function code to determine the write command. tells ESPHome that the following block is supposed to be interpreted as a lambda, or C++ code. For example, with the output button I made it's also possible to trigger a Bluetooth signal. block as plaintext. This condition performs an arbitrary piece of C++ code (see Lambda) 
The platform used is really an HA thing and helps HA determine what to do with the entity which is also an important concept. 
condition (Required, Condition): Sorry if it seems I am splitting hairs, but I do find the docs a bit of a maze and not very consistent (and yes, docs are hard!). By clicking Sign up for GitHub, you agree to our terms of service and Using this filter will only make the signal go high if the button has stayed high for more than 10ms, which should be more than enough to filter out the oscillation. For holding input registers the offset is in bytes. Next, theres the weird |- character combination. It will instead oscillate a bit before switching. // Acknowledge new state by publishing it. This action executes the script. when the switch is turned off. With the script: component you can define a list of steps in a central place, and then A new version has been release since you last visited this page: 2022.6.2 . I'd suggest this is a very likely use of this so would be useful to include it. You can also publish a state to a template switch from elsewhere in your YAML file
if it fails to connect to the network without a reboot), sensor.on_value / sensor.on_raw_value / sensor.on_value_range, binary_sensor.on_press / binary_sensor.on_release / and can be used to create conditional flow in actions. A new version has been release since you last visited this page: 2022.6.2 . / light.control / light.dim_relative It isnt an issue if the physical toggle switch is the only element controlling whatever device might be hooked up to the ESP8266 or ESP32. ALWAYS_ON - Always initialize the pin as ON on bootup. after it switched As restore_mode is not in the example, it would be unclear if that was part of the output block or the switch block. you could have just written lambda: |-. use a single delay action, then in your automation check script.is_running condition for a list of available options. There's no Generic Switch Output, there's a Generic Output Switch. custom data must contain all required bytes including the modbus device address. For example, here There is no example of a momentary switch on the Button documentation. This Condition checks if the given switch is ON (or OFF). and requires Modbus Controller to be configured. Suppose you have this configuration file: With this file you can already perform some basic tasks. Thanks for your time and effort to improve the docs - it is appreciated . name (Required, string): The name of the switch.

an optional value lambda. Switches come in many different shapes and forms. Hmm, I see your point, maybe I should move the GPIO stuff to a separate example below. sensor in the frontend. // This will be called every time the user requests a state change. An output is anything that can output a signal: a GPIO pin, an AC dimmer, various I/O port expanders, or even something more higher level such as Bluetooth signal. Each action is separated by a dash and multiple actions can be executed in series by just adding another - If its different from the last internal state, its additionally published to the frontend. advanced stuff (see the full API Reference for more info). A switch is a switch and a light is a light. (usually Home Assistant) without the user manually enabling it (via the Home Assistant UI). Possible return values for the optional lambda: return true; if the switch should be reported as ON. In electronics, this is called debouncing. Lambda to be evaluated every update interval to read the status of the switch. return {}; if the last state should be repeated. (Beware that effectively disables the reboot watchdog, so you will need to power cycle the device ALWAYS_ON - Always initialize the pin as ON on bootup. the switch is currently on or off: A new version has been release since you last visited this page: 2022.6.2 . name lambda is used instead of Home Assistants template lingo to avoid confusion. Sometimes youll also need a timer which does not perform any action, that is ok too, just The gpio switch platform allows you to use any pin on your node as a So it is highly recommended to use hardware interlocks (like SPDT-type relays) that ensure interval (Required, Time): The interval to execute the action with. A simple push on this button should toggle the state of the dehumidifier. Useful for motors where immediately turning on in the other direction could cause problems. Please note that this only works with some component types and others will result in a The state to publish. For restoring on ESP8266s, also see esp8266_restore_from_flash in the lambda (Optional, lambda): A light does not need a switch. global variables can be used to store the state of a garage door. interlock (Optional, list): A list of other GPIO switches in an interlock group. If you want to use a timeout, the term condition is required: condition (Required): The condition to wait to become true. ota.on_end / ota.on_error / https://esphome.io/components/switch/output.html, since I can toggle via the light component, does. of hiding one of them when the switch is ON/OFF. Because the offset for holding registers is given in bytes and the size of a register is 16 bytes the start_address is calculated as start_address + offset/2, A new version has been release since you last visited this page: 2022.6.2 . But before you go ESP_LOGD("main","Modbus Switch incoming state = %f",x); // return false ; // use this to just change the value, payload.push_back(0x1); // device address, payload.push_back(0x5); // force single coil, payload.push_back(0x00); // high byte address of the coil, payload.push_back(0x6); // low byte address of the coil, payload.push_back(0xFF); // ON = 0xFF00 OFF=0000. start or stop the motor of the gate. The switch domain includes all platforms that should show up like a The difference seems subtle, but it's important: it is a switch that uses an output, not an output that uses a switch. then (Required, Action): The action to perform until the condition evaluates to false. ota.on_state_change, script.execute / script.stop / script.wait, switch.toggle / switch.turn_off / switch.turn_on, light.toggle / light.turn_off / light.turn_on Sign in single: Do not start a new run. You can also call this action from the script itself, and any subsequent action note: because the response contains data for all registers in the same range you have to use data[item->offset] to get the first response byte for your sensor. You can pick from any of the supported device classes in Home Assistant: There is one issue with this setup, though. id (Required, ID): The ID of the template switch. deactivate them. Already on GitHub? All you have to do is to connect one end (also known as terminal) of the switch to the ground on the ESP8266 or ESP32 board (marked with a G on the board) and the other end to one of the GPIO pins. What this effectively says that if the thing inside Use this In this example the variable num_executions is incremented by one each time the
This action turns a switch with the given ID off when executed. However one little drawback to this is that the input_boolean is not associated with the ESPhome device in the frontend. The component calculates the size of the range based on offset and size of the value type a shorthand way of writing a while action with an empty then block.). the same principles apply here. state (Required, boolean, templatable):
In itself, the button or remote can not know if it opens For example, The text was updated successfully, but these errors were encountered: A better implementation would be something like this, that avoids the unnecessary switch: Momentary switches in general are a hack from when buttons didn't exist, so I'd rather remove them from the documentation than make them more prominent. I now use Unraid as my operating system, and Home Assistant happily runs in a Docker container. It can be turned on and off by HA or by an automation in esphome. The output switch platform allows you to use any output component as a switch. For that reason, I advise against using toggle switches on ESPHome projects, even if they are fun to play around with. Lets begin with an example to explain these concepts. Within this block, you can define several actions. I've implemented the output button with documentation for the next release (see here), but I'll leave this one open as something should also be done with the Momentary Switch section. Without it, the YAML parser would attempt to read the following block as if cycle back to its original state. A switch can control many things, including other devices connected to the ESPHome node, such as an LED strip or a relay. What is in ESPHome the relationship between binary_switch, switch and output? variables like so. skip_updates (Optional, int): By default all sensors of a modbus_controller are updated together. RESTORE_DEFAULT_OFF (Default) - Attempt to restore state and default to OFF if not possible to restore. condition (Required, All Conditions): The condition to check which branch to take. / cover.template.publish / switch.template.publish id (Optional, ID): Manually specify the ID used for code generation. to your account. ideally the IoT should work without an internet connection and should not break with compile error. There are also other triggers like on_release, on_click or on_double_click available. right after the switch component has acknowledged the state (e.g. This can either be solved by using a physical pull-up resistor. Lets look at an example icon (Optional, icon): Manually set the icon to use for the (If youre new to Home Assistant, a cover is of the given id is running, not how many. execute the script with a single call. with lambdas, its always best to look at the generated C++ source file under
First, we have to give the dehumidifier a ID so that we can RESTORE_DEFAULT_OFF (Default) - Attempt to restore state and default to OFF if not possible to restore. In the first example, this range is defined as any value above or including
name (Required, string): The name of the sensor. switch(es). See Conditions. ESPHome has another extremely powerful tool to offer: Templates. For example, this configuration would achieve your desired behavior: Woah, hold on there. For coil and discrete input resisters the LSB of the first data byte contains the coil addressed in the request. 65.0, and the second one refers to once the humidity reaches 50% or below. Just give each switch in the interlocking group an interlock option then (Required, Action): The action to repeat. This part is called a trigger. output is an internal status of GPIO13 I am not sure of this one report ON states as OFF and vice versa. Automations and templates are two very powerful aspects of ESPHome. switch is the actual electrical relay but can be used in complex lambda expressions. See switch.on_turn_on / switch.on_turn_off Trigger. count (Required, int): The number of times the action should be repeated. or just | or >. I would have guessed this output would be the Generic Switch Output. RESTORE_INVERTED_DEFAULT_ON - Attempt to restore state inverted from the previous state and default to ON. Theyre a powerful tool to automate almost allow you to perform actions under certain conditions and templates are a way to easily Heres a bit of a primer: First, you might have already wondered what the lambda: !lambda |- part is supposed to mean. Because the write command only touches one register start_address and offset have to be corrected. ESPHome always initializes outputs to off on boot. I'll put this out here - the output docs are really confusing! API. This component allows you to run actions at fixed time intervals. But I can't figure out what switch platform to use for this. Defaults to no. Automations offset from start address in bytes. For example below you can see an automation that checks if a sensor value is below 30 and if so something like a window blind, a roller shutter, or a garage door.)
first: Whats happening here? Be careful: on the ESP8266, you only have a total of 96 bytes available for this! Defaults to false. output (Required, ID): The ID of the output component to use. inverted (Optional, boolean): Whether to invert the binary of the sensor is within a certain range. While ESPHome does not provide a construction for timers, you can easily implement them by hopefully a bit easier to read and understand than Home Assistants. (You may also have seen variations of this like >- max_runs (Optional, int): Allows limiting the maxiumun number of runs when using script Note the terminology or else evaluate the second block. delay action, wait_until action, or is inside a while loop, etc. This action allows your automations to wait until a condition evaluates to true. time period. That was what I did in the original switch setup - can the same be done for a output setup? Read on to find out more on how I got started with Home Assistant. In this example, the device class is set to be a window. For the cases where the pure YAML automations dont work, Would that example hide it from HA? ON/OFF itself). pin (Required, Pin Schema): The lambda (Optional, lambda): The state of the template cover is The other coils follow toward the high-order end of this byte and from low order to high order in subsequent bytes. with the switch.template.publish action. I actually tried that but you have to set a turn_on action otherwise it would give me an error in Home Assistant. To create an active-low switch (one that is turned off by default), use the Pin Schema: To create momentary switches, for example switches that toggle a pin for a moment, you can use Since offset is not zero the read command is part of a range and will be parsed when the range is updated. is above 65%, and make it turn off again when it falls below 50%: Thats a lot of indentation on_value_range is a special trigger for sensors that trigger when the value output using the C++ (Arduino) API. time (Required, templatable, Time): must equal the number of items in the return statement of the lambda.
any command sent to the template switch will immediately update the reported state. restore_state (Optional, boolean): Sets whether ESPHome should attempt to restore the will not be executed. It makes sense that they're all called output, because at a high level they all do the same. Is there a robust solution to ensure 'off' at startup? [edit] This Action allows you to change the value of a global modes queued and parallel, use value 0 for unlimited runs. to interact with the script using the script actions. EDIT - I tried to have binary_sensor to use output to trigger the GPIO but the firmware would not compile. script is not running, it does nothing. Similarly, at reset time (before any of ESPHomes code runs)
Issue a warning. Theres a slight difference in how these different styles deal with whitespace, but for our controlled by a template, or lambda. to know if your timer is going or due. Like this: https://i.imgur.com/oxXGGfh.png, I'd probably go with a template switch: https://esphome.io/components/switch/template.html. For example, switch.toggle and the line after that form an Sure :) Lets step through whats happening here. This action executes an arbitrary piece of C++ code (see Lambda). Defaults to doing nothing. ALWAYS_OFF - Always initialize the pin as OFF on bootup. script was already running.
them into the generated C++ code. See Conditions. This action allows you to repeat a block a given number of times. the automation in the next few lines will execute whenever someone begins to press the button. This will make the Home Assistant frontend show buttons for both ON and OFF actions, instead A new version has been release since you last visited this page: 2022.6.2 . / media_player.volume_up / media_player.volume_down / media_player.volume_set, binary_sensor.is_on / binary_sensor.is_off, wifi.connected / api.connected
x (float): The float value to be sent to the modbus device. A configuration that works for me and creates a Button Entity in HomeAssistant. to wait after other items in an interlock group have been disabled before re-activating. esp8266 section. a block until a given condition evaluates to false. In some cases it is necessary to ensure that two outputs are never active at the same time. Commentdocument.getElementById("comment").setAttribute( "id", "ad275e46d456ee4a330ab42f3b0a6290" );document.getElementById("c08a1a06c7").setAttribute( "id", "comment" ); I have read and accept the Privacy Policy. When I first did this (as a momentary switch) it took me quite a while to find the right bit of the docs. restart: Start a new run after first stopping previous run. everything on your device with an easy-to-use syntax. then (Optional, Action): The action to perform if the condition evaluates to true. All these components are interchangable everywhere an output is used. restore_mode (Optional): Control how the GPIO Switch attempts to restore state on bootup. Like a gpio pin. Defaults to never timing out. By that, I mean that you might have set the software switch to on while the hardware switch is in the off position. Press J to jump to the feed. See https://developers.home-assistant.io/docs/core/entity/switch/#available-device-classes The template switch platform allows you to create simple switches out of just actions and It can be turned on and off by HA or by an automation in esphome. An output is the conduit between the light component and the real world. Similarly you can have a single trigger with multiple automations: As a last example, lets make our dehumidifier smart: Lets make it turn on automatically when the humidity reported by a sensor In some cases you might require to share a global variable across multiple lambdas. I'd suggest adding it to the example if you can. / mqtt.connected, sun.is_above_horizon / sun.is_below_horizon. / text_sensor.template.publish, stepper.set_target / stepper.report_position The button I created is a Generic Output Button: it's a button that uses an output. [edit] Just to say in the doc you have created, it is a little unclear which block the 'Configuration Variables' refers to (output or button). that two GPIOs are never active at the same time. My thoughts were mainly that there should be something in the docs as it seems a common task that needs a solution. id (Optional, ID): Manually specify the ID used for code generation. An output button would probably also be useful, As I say, I am not fussed what the correct solution is, just I think there should be something in the docs . Because of this, it ESPHome can sometimes read the wrong values (such as a very rapid switching from one value to the other before it finally switches). the delay is happening. on_turn_off (Optional, Action): An automation to perform A light does not need a switch.
You can adjust this behavior (or even disable automatic rebooting) using the reboot_timeout option If MQTT enabled, All other options from MQTT Component. return false; if the switch should be reported as OFF. Like a gpio pin. An example that uses a single relay to activate a remote control button. If custom_command is used address and register_type cant be used.
