Flash LED light bulb and make them available in Homebridge/Homekit

Hello!

I have some LED light bulbs which are marked as XLD-W60-1.1. I have to use the DoHome app to make them work but they tend to be unreliable. After a while, they become unresponsive and I have to do all sorts of magic and reboot, etc. to resurrect them. So I came across the application Tuya-convert which makes it possible to flash devices without the need to solder wires. I was wondering if someone has successfully done so with such a light bulb? I have seen I could use the Tasmota firmware and then get somehow my Homebridge to communicate with them. But then there is (maybe even better) HAA on GitHub which makes it possibly talking directly to HomeKit. I don't know if this light bulb would be compatible with this technique? I can't take it further apart besides breaking it and then reglueing the whole thing back together.

Hello, what is the marking on the WiFi module here?

There is nothing more than this what's visible I can just barely read DOHOME when looking into the hole. I would have to remove all the glue etc to look further inside. Can't one find this out by other means?

Well, as far as I know, tuya-convert will not break the bulb if it has non-supportable WiFi module, then you can always try... it won't hurt.

Another thing to watch for would be the "Bluetooth" marking or Bluetooth pairing. That would indicate that device inside is non ESP8266, so it could be BK7231:

It is also possible to change firmware by soldering wires:

Bought dohome homekit downlight before, and it had an esp8266. Not the same as yours but could also have the same esp chip
You're gonna have to remove the glue, and open it up since it's the only way the access the pins
I don't think tuya-convert would work since it's not even running tuya firmware
That looks like a DT Light

You can flash it with HAA for native homekit

I just tried to remove the glue and to remove the board. But there is no way to take this out without breaking things. How are those things usually assembled? What can I take apart? For example, the chip with the antenna, could I just pull on it? Is there a connector at the bottom (usually)?
Thanks!

@kapabel just pry the top with screwdriver or pryer
You don’t have to pull put the pcb since it looks you have enough space to connect all the pins

I boldly emailed the manufacturer who told me it's a BL602. Is there something I can do with this chip as an over the air update? Or do I have to solder?

@kapabel i’d recommend to just open it up to confirm the chip. They could’ve sold you an older batch that still has esp

If it’s indeed bl602, then openbeken is the way, then use homebridge with mqtt plugin to expose to homekit

If you really need it with native homekit firmware, then swapping it with esp chip is another way to do it
