H801/H802 RGBW LED controller

If you have an H802, read this page, then scroll down to the H802 section.

The H801 is pretty affordable and easy to hack and adapt to your needs. It can be found on AliExpress and other sites. The board is based on an ESP8266EX chip.

It has 5 seperate PWM outputs (each driven by a DTU35N06 MOSFET rated for 106W max power), and can be used as a RGB / RGBW / RGBWW / RGBCT controller or configured with any combination of up to five individual monochromatic PWM lights.

See A closer look at the H801 LED WiFi Controller for more details on the hardware.

Sample configuration

You can use the RGBWW and the ESP8266 Software PWM output components using below configuration:

esphome:
  name: h801light

esp8266:
  board: esp01_1m

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

logger:

output:
  - platform: esp8266_pwm

    id: pwm_w2

    red: pwm_r
    green: pwm_g
    blue: pwm_b
    cold_white: pwm_w1
    warm_white: pwm_w2

For RGBW lights, the pwm_w2 output is not used (and can be removed):

    green: pwm_g
    blue: pwm_b
    white: pwm_w1

Flashing

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. esphome-flasher <esphome-flasher>

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.

binary_sensor:
  - platform: gpio
    pin: GPIO3
    name: "GPIO3-TX Motion"
    device_class: motion

Pinout

Function	ESP Pin
R (PWM1)	GPIO15
G (PWM2)	GPIO13
B (PWM3)	GPIO12
W1 (PWM4)	GPIO14
W2 (PWM5)	GPIO4
Jumper J3	GPIO0
RX	GPIO2
TX	GPIO3
LED D1 (red)	GPIO5
LED D2 (green)	GPIO1

H802

The H802 is a very similar device, with four channels (RGBW) instead of five.

It looks like this:

Pinout:

Function	ESP Pin
R (PWM1)	GPIO14
G (PWM2)	GPIO12
B (PWM3)	GPIO13
W (PWM4)	GPIO15
Jumper J3	GPIO0
RX	GPIO3
TX	GPIO2

Unlike the H801, the H802 has no LEDs of its own. Note that the RGBW pinout is reversed compared to the H801.

When flashing, instead of connecting 3V3, you can power the device from its usual power supply. Connect RX to TX and TX to RX.
