@ -857,6 +857,20 @@ output `VALUE`. VALUE should be 0 or 1 for "digital" output pins. For
PWM pins, set to a value between 0.0 and 1.0, or between 0.0 and
`scale` if a scale is configured in the output_pin config section.
`SET_PIN PIN=config_name TEMPLATE=<template_name> [<param_x>=<literal>]`:
If `TEMPLATE` is specified then it assigns a
[display_template](Config_Reference.md#display_template) to the given
pin. For example, if one defined a `[display_template
my_pin_template]` config section then one could assign
`TEMPLATE=my_pin_template` here. The display_template should produce a
string containing a floating point number with the desired value. The
template will be continuously evaluated and the pin will be
automatically set to the resulting value. One may set display_template
parameters to use during template evaluation (parameters will be
parsed as Python literals). If TEMPLATE is an empty string then this
command will clear any previous template assigned to the pin (one can
then use `SET_PIN` commands to manage the values directly).
