Yet another MagicHome RGB controller. I specifically had this one: https://www.aliexpress.com/item/DC5-24V-Wireless-WIFI-LED-RGB-Controller-RGBW-Controller-IR-RF-Remote-Control-IOS-Android-for/32827253255.html
Aside from it going 9-28v, there are no other external model numbers etc, however opening it up revealed a very different configuration inside, using an ESP8285 chip directly on the board.

## Identifying this board
Looking closely you can see it's an ESP8285, on the main board, it has the part number: `ZJ-WFMN-B V1.1`

## Flashing
I found that on the back it has pads to solder to so you can flash it.

The `IO0` port is `GPIO0` that needs to be pulled to ground when powered on for flashing (as per all ESP devices). I soldered cables to each of these. Note that some are very close to other pads, so be careful.

## Configuration
Once flashed, I configured it as follows (using Tasmota v6.1.1):
| Field | Value |
|---|---|
|Module type|18 Generic|
|D1 GPIO5|38 PWM2|
|D6 GPIO12|39 PWM3|
|D7 GPIO13|40 PWM4|
|D5 GPIO14|37 PWM1|
With all that done, one of the critical things I needed to do so I could set the colors was to run the command to set `SetOption15` to `1`. For me, this was sending the MQTT command (you will need to adjust for your config):
```
mosquitto_pub -t 'cmnd/rgbled/SetOption15' -m '1'
```
Once the above was done and the device rebooted, I could set the colors using commands such as (to turn on red and white full):
```
mosquitto_pub -h openhab.sf -t 'cmnd/rgbled/color' -m '#ff0000ff'
```
