:description: Instructions for setting up a Shelly Dimmer 2.

|
|
|
|
The ``shelly_dimmer`` component adds support for the dimming and power-metering functionality that can be found the `Shelly Dimmer 2 <https://shelly.cloud/knowledge-base/devices/shelly-dimmer-2/>`_. The interaction with mains is done via an STM32 microcontroller that is flashed with an `open source firmware <https://github.com/jamesturton/shelly-dimmer-stm32>`_.
|
|
A detailed analysis of the Shelly Dimmer 2 hardware is given `here <https://github.com/arendst/Tasmota/issues/6914>`_.

An example of a configuration of this component:
|
|
|
|
.. code-block:: yaml
|
|
|
|
logger:
|
|
baud_rate: 0
|
|
|
|
uart:
|
|
tx_pin: 1
|
|
rx_pin: 3
|
|
baud_rate: 115200
|
|
sensor:
|
|
|
|
light:
|
|
- platform: shelly_dimmer
|
|
name: Shelly Dimmer 2 Light
|
|
id: thislight
|
|
power:
|
|
name: Shelly Dimmer 2 Light Power
|
|
voltage:
|
|
name: Shelly Dimmer 2 Light Voltage
|
|
current:
|
|
name: Shelly Dimmer 2 Light Current
|
|
max_brightness: 500
|
|
firmware:
|
|
version: "51.6"
|
|

|
|
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the UART hub.
|
|
|
|
.. note::
|
|
|
|
Currently, only the first hardware UART of the ESP is supported, which has to be configured like this:
|
|
|
|
.. code-block:: yaml
|
|
|
|
uart:
|
|
tx_pin: 1
|
|
rx_pin: 3
|
|
baud_rate: 115200
|
|
|
|
|
|
- **name** (**Required**, string): The name of the light.
|
|
- **leading_edge** (*Optional*, boolean): `Dimming mode <https://en.wikipedia.org/wiki/Dimmer#Solid-state_dimmer>`_: ``true`` means leading edge, ``false`` is trailing edge. Defaults to ``false``.
|
|
- **min_brightness** (*Optional*, int): Minimum brightness value on a scale from 0..1000, the default is 0.
|
|
- **max_brightness** (*Optional*, int): Maximum brightness value on a scale from 0..1000, the default is 1000.
|
|
- **warmup_brightness** (*Optional*, int): Brightness threshold below which the dimmer switches on later in mains current cycle. `This might help with dimming LEDs <https://github.com/jamesturton/shelly-dimmer-stm32/pull/23>`_. The value is from 0..1000 with an default of 0.
|
|
- **nrst_pin** (*Optional*, :ref:`config-pin`): Pin connected with "NRST" of STM32. The default is "GPIO5".
|
|
- **boot0_pin** (*Optional*, :ref:`config-pin`): Pin connected with "BOOT0" of STM32. The default is "GPIO4".
|
|
- **current** (*Optional*): Sensor of the current in Amperes. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **voltage** (*Optional*): Sensor of the voltage in Volts. Only accurate if neutral is connected. All options from :ref:`Sensor <config-sensor>`.
|
|
- **power** (*Optional*): Sensor of the active power in Watts. Only accurate if neutral is connected. All options from :ref:`Sensor <config-sensor>`.
|
|
- **firmware** (*Optional*):
|
|
|
|
- **version** (*Optional*): Version string of the `firmware <https://github.com/jamesturton/shelly-dimmer-stm32>`_ that will be expected on the microcontroller. The default is "51.6", another known-good firmware is "51.5".
|
|
- **url** (*Optional*, string): An URL to download the firmware from. Defaults to github for known firmware versions.
|
|
- **sha256** (*Optional*): A hash to compare the downloaded firmware against. Defaults a proper hash of known firmware versions.
|
|
- **update** (*Optional*): Should the firmware of the STM be updated if necessary? The default is false.
|
|
|
|
.. note::
|
|
|
|
When flashing Shelly Dimmer with esphome for the first time, flashing the STM firmware is necessary too for the dimmer to work:
|
|
|
|
.. code-block:: yaml
|
|
|
|
firmware:
|
|
version: "51.6" #<-- set version here
|
|
update: true
|
|
|
|
|
|
- All other options from :ref:`Light <config-light>`.
|
|
|
