H801 RGBW LED controller
|
|
========================
|
|
|
|
The H801 is pretty affordable and easy to hack and adapt to your needs. It can be found on `AliExpress <https://s.click.aliexpress.com/e/bbnUDBZW>`__
|
|
`Here <http://tinkerman.cat/closer-look-h801-led-wifi-controller/>`__ is an article about the
|
|
hardware for those who have an interest for more details about the board.
|
|
It can be used as a RGB, RGBW, RGB dual white or even control 5 individual monochromatic strips if you want or combinations of these.

For ESPHome, you can then use the :doc:`RGBW </components/light/rgbw>`
|
|
and the :doc:`ESP8266 Software PWM output </components/output/esp8266_pwm>` components using below configuration:
|
|
|
|
.. code-block:: yaml
|
|
|
|
esphome:
|
|
name: h801light
|
|
|
|

|

|

|

|

|
|

|
|
|

|
|
Make your node in the ESPHome dashboard and compile/upload it.
|
|
(if it fails OTA it must be uploaded manually with your favorite ESP flasher,
|
|
e.g. :ref:`esphome-flasher <esphome-flasher>`)

This LED strip can be used with the sketch as-is
|
|

|
For this type of led strip you have to swap the white and blue GPIO numbers in the sketch.
|
|
|
|
You will need to solder pins to the board inside the H801 (fortunately it's pretty roomy and
|
|
not a lot of components or stuff in the way apart from the 2 wires on the back).
|
|
|
|
3.3V, GND, TX and RX (RX to RX and TX to TX) needs to be connected to your serial adapter, the
|
|
two other pins must be shorted throughout the flashing process by a jumper or a breadboard cable.
|
|
(Remember to remove it after flashing)
|
|
|
|
Add A PIR(Motion) Sensor
|
|
------------------------
|
|
|
|
It's possible to use the header that was soldered on for flashing as an input.
|
|
The example below uses the TX pin as a PIR motion sensor input:

|

|
|
|
|
The following can be appended to the YAML file for your H801 to configure the TX pin as a motion
|
|
sensor input.
|
|
|
|
.. code-block:: yaml
|
|
|
|
binary_sensor:
|
|
- platform: gpio
|
|
pin: GPIO3
|
|
name: "GPIO3-TX Motion"
|
|
device_class: motion
|
