I have bought an Tsong WiFi LED Panel 60x60cm CCT 3000K - 6000K 36W 100lm/W Edge-lit with an TYWE3L chip in the controller which i want to flash to esphome to use local in my HA setup.
More details here: WiFi LED Paneel CCT 60x60 • Warm tot Koudwit | LEDWINKEL-Online
The controller has a TYWE3L chip which i think is an esp8266 variant which can be flashed…? But how do i determine the configuration that is needed once i flashed the chip for this device? I can’t seem to find someone that has also converted this LED panel. I did flash some chips before to esphome, f.e. my AC, but there was always a configuration available that i simply uploaded and my device was working. Now for this panel i haven’t found a configuration.
Inside tuya app the device is working perfectly, i can adjust the color, dimm the light and switch it on and off.
i just looked at the pinout of the chip, i think i can determine what is what on the pcb. But whats next? i need a config to set brightness, on/off, colour temperature etc…
please mind i want to make a config for my LED panel controller. with tracing i can determine which commands are send and this way write a working esphome config?
This looks very similar to what you have, it is a batten rather than a panel and you would have to confirm the GPIO connections but might help you start.
Today i finally found some time to work on this project. I managed to get the light working, brightness as well as the color temperature control with ESPHOME light component (Cold White + Warm White Light)
The LED panel has a memory function, this means the light brightness and colors are restored after a power cycle. This way you can simply replace the controller with an existing light bulb.
But since i want to have dimmed light at night and a normal light during the day, i added an extra binary sensor in the ESPHOME config. I’m going to power the LED panel controller constantly on 230V and use the switch in the wall to switch on/off the light. Since the controller, and thus the ESPHOME instance is constanly up, i can change the prefered brightness at all times.
Below my ESPHOME config:

name: badkamerledpanel

I changed my config a bit so i can use the regular lightswitch in the wall to switch the light on or off, regardless of it’s state. I used the light.toggle, because the light may have been switch on by a HA automation.
on_state:
then:
- light.toggle: badkamerlight
During the night I prefer the light to be dimmed as low as possible, and in the morning/day the light brightness is set to ± 60%.
My automation triggers on specific times and sets the light brightness and color. Immediatly after the light is switched off. (the light doesn’t visibly switches on, but does have presets loaded)
This way, when someone switches the light to on with the wall switch, the brightness and color is preset to the right setting of that time of the day
