|
|
This component has not been fully tested yet, if you are testing this component
|
|
please share your experience with the dimmer hardware and light model and
|
|
configuration here https://github.com/esphome/feature-requests/issues/278
|
|
|
|
Thanks!

|
The ``ac_dimmer`` component allows you to connect a dimmable light or other load
|
|
which supports phase control dimming to your ESPHome project.
|
|
|
|
There are several already made boards which are compatible with this integration,
|
|
for example the `RobotDyn dimmer
|
|
<https://robotdyn.com/ac-light-dimmer-module-1-channel-3-3v-5v-logic-ac-50-60hz-220v-110v.html>`__.

# Example configuration entry
|
|
output:
|
|
- platform: ac_dimmer
|
|
id: dimmer1
|
|
gate_pin: D7
|
|
zero_cross_pin:
|
|
number: D6
|
|
mode: INPUT
|
|
inverted: yes
|
|
|
|
light:
|
|
- platform: monochromatic
|
|
output: dimmer1
|
|
name: Dimmerized Light
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **gate_pin** (**Required**, :ref:`config-pin`): The pin used to control the Triac or
|
|
Mosfet.
|
|
- **zero_cross_pin** (**Required**, :ref:`config-pin`): The pin used to sense the AC
|
|
Zero cross event, you can have several dimmers controlled with the same zero cross
|
|
detector, in such case duplicate the ``zero_cross_pin`` config on each output.
|
|
- **method** (*Optional*): Set the method for dimming, can be:
|
|
|
|
- ``leading pulse`` (default): a short pulse to trigger a triac.
|
|
- ``leading``: gate pin driven high until the zero cross is detected
|
|
- ``trailing``: gate pin driven high from zero cross until dim period, this method
|
|
is suitable for mosfet dimmers only.
|
|
|
|
- **init_with_half_cycle** (*Optional*, boolean): Will send the first full half AC cycle
|
|
Try to use this for dimmable LED lights, it might help turning on at low brightness
|
|
levels. On Halogen lamps it might show at initial flicker. Defaults to ``False``.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- All other options from :ref:`Output <config-output>`.
|
|
|
|
Dimming lights with phase control can be tricky, the minimum level your light turns on
|
|
might be different from other lights, also the perceived light level might not correlate
|
|
to the percentage output set to the light, to try to minimize these behaviors you can
|
|
tweak the values ``min_power`` from this output component and also ``gamma_correct`` from
|
|
the monochromatic light.
