Hi, so blakadder dumped a firmware from a tuya matter relay device which is using a bk7231n. I thought they might be using the newer tuya chips for matter support, but apparently not. Device link -> Firmware dump: Which brings me to my question if there's any plan to include matter support for...

Yes, this is planned, I just need to get some background stuff first, currently I do not even know what would be a good hub to test Matter protocol. I may use Tasmota code as reference, as we are license-compatible. Do you need Matter support in OBK on your side?

Alexa or Google speakers hub would be a decent choice From my test with matter on tasmota: RCBCW Light bulb: - You can only enable warm/cold light or rgb light, not both. At least for now Alexa: - Doesn't support multi relay yet (for more than 1 gang switches), if added to alexa, you can only control the 1st relay. Seems to be alexa's limitation of matter Google: - Has a specific requirement to add device to matter

>>20801284 hello, Google Nest Hub v2 is a very good device to test Matter with. It supports Matter over WiFi and over Thread. BTW is there any possibility to support Thread within N7231N

@p.kaczmarek2 any news regarding Matter support? It start to be the mainstream. IKEA release 20 new Matter devices in January 2026. It should have Beken chipset inside so would be nice to have same Matter functionality in the opensource firmware.

Which brings me to my question if there's any plan to include matter support for future updates with openbk?

Do you need Matter support in OBK on your side"?

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
