Slow PWM Output

:description: Instructions for setting up slow pwm outputs for GPIO pins.

|
|
|
|
Similar to PWM, the Slow PWM Output platform allows you to control GPIO pins by
|
|
pulsing them on/off over a longer time period. It could be used to control a
|
|
heating element through a relay where a fast PWM update cycle would not be appropriate.
|
|
|
|
.. note::
|
|
|
|
This is for **slow** PWM output. For fast-switching PWM outputs (for example,
|
|
lights), see these outputs:
|
|
|
|
- ESP32: :doc:`ledc`
|
|
- ESP8266: :doc:`esp8266_pwm`

# Example configuration entry
|
|
output:
|
|
- platform: slow_pwm
|
|
pin: D1
|
|
id: my_slow_pwm
|
|
period: 15s
|
|
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin to pulse.
|
|
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
|
|
- **period** (**Required**, :ref:`config-time`): The duration of each cycle. (i.e. a 10s
|
|
period at 50% duty would result in the pin being turned on for 5s, then off for 5s)
|
|
- All other options from :ref:`Output <config-output>`.
