esphome switch platforms

Links between the Momentary switch docs and the Button docs would also benefit users. interlocking. with lambdas, its always best to look at the generated C++ source file under /src/main.cpp. Depending on how you've wired the ESP and garage door it might be high when the ESP is off or on boot, but there's nothing ESPHome can do about that from software. esp8266 esp transceiver esphome esp01 pwm controlling RESTORE_DEFAULT_OFF (Default) - Attempt to restore state and default to OFF if not possible to restore. interlock (Optional, list): A list of other GPIO switches in an interlock group. report ON states as OFF and vice versa. This action first evaluated a certain condition (if:) and then either restore_state (Optional, boolean): Sets whether ESPHome should attempt to restore the custom_command (Optional, list of bytes): raw bytes for modbus command. There are also other triggers like on_release, on_click or on_double_click available.

address (Required, int): start address of the first register in a range, offset (Optional, int): not required in most cases Once defined, it will automatically appear in Home Assistant Defaults to false. ALWAYS_OFF - Always initialize the pin as OFF on bootup. Sure :) Lets step through whats happening here. Lets look at an example Please note that its possible to achieve the same thing with the time.on_time id (Optional, ID): Manually specify the ID used for code generation. Similarly, at reset time (before any of ESPHomes code runs) the switch is currently on or off: A new version has been release since you last visited this page: 2022.6.2 . Defaults to false. Theres a slight difference in how these different styles deal with whitespace, but for our For example A value of 5 would only update this sensor range in every 5th update cycle. id (Optional, ID): Manually specify the ID used for code generation. This issue has been automatically marked as stale because it has not had recent activity. [edit]

Like a gpio pin. Sign in please consider the following setup (I omitted the general parts, not related to the switching or light part): There is no switch and the light component still switches the power on and off (through output). First, we define a binary sensor (with the id top_end_stop) and then a Like this: https://i.imgur.com/oxXGGfh.png, I'd probably go with a template switch: https://esphome.io/components/switch/template.html. ALWAYS_OFF - Always initialize the pin as OFF on bootup. I'd suggest this is a very likely use of this so would be useful to include it. everything on your device with an easy-to-use syntax. How about an input_boolean? One that links an action to the hardware and a second that initiates that link (perhaps not the best description). All automations you define in ESPHome are executed on the ESP itself and will continue to If multiple instances turns on a light for 5 seconds. For the registers offset is the position of the relevant bit. See https://developers.home-assistant.io/docs/core/entity/switch/#available-device-classes The state to publish. This guide will show you how to do it right. will not be executed. follows what you would call these events on mouse buttons. When I first did this (as a momentary switch) it took me quite a while to find the right bit of the docs. all of the usual lambda syntax. // part of the light color will be determined by the sensor value. This condition allows you to check if a given script is running. To store local variables inside lambdas that retain their value across executions, you can create static item (const pointer to a Switch derived object): The sensor object itself. payload (std::vector&payload): empty vector for the payload. Because the write command only touches one register start_address and offset have to be corrected. for a list of available options. The state of this switch will then be used against a Lambda in ESPhome. somewhere else, like top_end_stop) and lets you call any of ESPHomes many APIs directly. the automation in the next few lines will execute whenever someone begins to press the button. ALWAYS_ON - Always initialize the pin as ON on bootup. I would have guessed this output would be the Generic Switch Output. Lambda to be evaluated every update interval to read the status of the switch. For example, controlled by a template, or lambda. ESPHome has another extremely powerful tool to offer: Templates. In this example, [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). on_turn_on trigger. (You may also have seen variations of this like >- For example if you want to toggle a switch every minute, you can use this component. Requires Home Assistant 2021.9 or newer.

The length here be performed when the remote (like Home Assistants frontend) requests the switch to be turned off. but can be used in complex lambda expressions. to it later in lambdas. You could, for example, build a master light switch using several buttons to control every connected lightbulb in your smart home. Please explain whats going on here!

It will be closed if no further activity occurs. For coil and discrete input resisters the LSB of the first data byte contains the coil addressed in the request. This condition performs an arbitrary piece of C++ code (see Lambda) The while action executes In some cases it is necessary to ensure that two outputs are never active at the same time. deactivate them. script is not running, it does nothing. allow you to perform actions under certain conditions and templates are a way to easily If so, then I can see there is a restore_mode. This action turns a switch with the given ID on when executed. switches (Required, list): A list of switches to initialize. See switch.on_turn_on / switch.on_turn_off Trigger. turn_on_action (Optional, Action): The action that should start or stop the motor of the gate. something like a window blind, a roller shutter, or a garage door.) We now attach a special attribute on_press to the toggle button. return false; if the switch should be reported as OFF. I'll put this out here - the output docs are really confusing! combining script and delay. / light.addressable_set, cover.open / cover.close / cover.stop / If compilation fails or something else is not working as expected

In this example the variable num_executions is incremented by one each time the that two GPIOs are never active at the same time. turn_off()/turn_on(): Manually turn the switch ON/OFF from code. There's no Generic Switch Output, there's a Generic Output Switch. not be exposed to the frontend (like Home Assistant). What this effectively says that if the thing inside can write some basic (and also some more advanced) automations using a syntax that is if you have a light and want to set it to a pre-defined color when a button is pressed, you can do this: Every parameter in actions that has the label templatable in the docs can be templated like above, using If you wanted to use the physical toggle switch to turn the device on again, you would first have to switch it to off and then to on again. controlling everything strictly from the frontend is quite a pain. In this example, the device class is set to be a window. 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. id (Required, ID): The ID of the global variable to set. The gpio switch platform allows you to use any pin on your node as a script was already running. using the C++ (Arduino) API. This effectively tells the YAML parser to treat the following

// Acknowledge new state by publishing it. Example Binary Light - firstly it is defined in a different order in the example (which I realise in itself doesn't matter but I'm a sucker for consistency), but also should it be an Output Light (rather than Binary Light) to follow the same logic? While ESPHome does not provide a construction for timers, you can easily implement them by You can also call this action from the script itself, and any subsequent action using script modes single and restart respectively. customize everything about your node without having to dive into the full ESPHome C++ A light does not need a switch. By clicking Sign up for GitHub, you agree to our terms of service and condition (Required, All Conditions): The condition to check which branch to take. device_class (Optional, string): The device class for the switch. of the script are running in parallel, this will block until all of them have terminated. single: Do not start a new run. The other coils follow toward the high-order end of this byte and from low order to high order in subsequent bytes. A switch can control an output, see https://esphome.io/components/switch/output.html, Powered by Discourse, best viewed with JavaScript enabled. the relay GPIO pins may have pull-ups active, so the relay may be active before ESPHome can manually For example, with the output button I made it's also possible to trigger a Bluetooth signal. My goal is that any ESPHome beginner will be able to wire up a switch or button and configure it using YAML. Defaults state: Retrieve the current state of the switch. later use it inside our awesome automation. Now comes the actual automation block. For restoring on ESP8266s, also see esp8266_restore_from_flash in the lambda (Required, lambda): The lambda to run for instantiating the The entity_id in ESPHome does not have to be a component which is a sensor in Home Assistant, it can be anything. with a list of all the switches in the group. A press happens when you begin pressing the button/mouse. An output button would probably also be useful, so that you can do things like this: I have no problem with this. But in many cases, The switch domain includes all platforms that should show up like a If your device only supports Force Multiple Coils (function code 15) set this option to true. of hiding one of them when the switch is ON/OFF. Or you can choose the option for solving this issue. With if () { } else { } we create a condition. The example I show uses a GPIO Output, but it could use any other output as well.

The difference seems subtle, but it's important: it is a switch that uses an output, not an output that uses a switch. Useful for motors where immediately turning on in the other direction could cause problems. Set to "" to remove the default entity category. name (Required, string): The name for the switch. The crc is automatically calculated and appended to the command. EDIT - I tried to have binary_sensor to use output to trigger the GPIO but the firmware would not compile. id (Required, ID): The ID of the template switch. This action delays the execution of the next action in the action list by a specified 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.
