Device Name:
MagicHome RGB+CCT Controller (MINI-WF-5CH-A _v1.0)

URL to Device:
None. I've bought these 10 years ago and recently decided to play with them. The same hardware is not sold anymore

Used HAA version:
v12.13.4 Merlin

Summary of functions:
5 channel LED controller, rated at 9-28V <= 240W

MEPLHAA script:

{"c":{"io":[[[0],6],[[4,5,12,13,14],7]],"b":[[0,5]]},"a":[{"t":30, "s": 1, "g":[4,5,14,13,12],"b":[[0]]}]}

There are some strips where RED and GREEN are swapped, so in this case, the order of GPIO 4 and 5 in g should be swapped.

Long description:
This is an old MagicHome RGB+CCT LED controller. I've used it with 12V RGBW led strips and recently decided to look into a way to add it to HomeKit, leading me to play with this firmware.
The board version is MINI-WF-5CH-A _v1.0
It uses ESP8266

• esptool report the chip is ESP8266EX
• on the board, it is written ESP-F

As per ESP-F datasheet, in order to put this in UART Download mode

• GPIO15 must be set to low - it is low by default
• GPIO0 must be set to low - IO0 pinhole to GND
• GPIO2 must be set to high - there is no pinhole for this, nor for VCC/3v3 - for both, wires should be soldered directly to the ESP chip and connected together.

Finally power it through the DC jack and flash it. Ive used CP2102 under ubuntu (no drivers required) and esptool.

The RGBCCT channels are as following:

• GPIO4 - RED
• GPIO5 - GREEN
• GPIO14 - BLUE
• GPIO12 - CW
• GPIO13 - WW

A button could be soldered between GPIO0 and GND, enabling physical on/off switch and the ability to easily enter into setup mode (hold for 8 seconds)

Photos, additional information...:

There is IR with this controller, however i'm not using this, so I didn't bother trying to make it work.
