I think we need a zigbee device like SONOFF S-MATE2.
It will allow us to turn old switches into smarthome devices.
Personally, I would prefer the matter thrend versions.
There is a request on the forum for a similar device but in the M5/R5 style. But I think that both devices are needed in the sonoff product range.
The topic regarding new sonoff devices has already been discussed on the forum. But @Daniel_Zhan doesn’t speak much on this topic. I know that they are afraid to reveal their ideas and development plans.
