I have a bunch of cheap Xiaomi temperature sensors from China with the PvvX firmware flashed, integrated with Home Assistant. They're all SKU NUN4106CN. The model appears to be LYWSD03MMC on the version I have, not sure about the PBTech version.

PBTech sells this model, NUN4126GL. Does anyone know if these can be flashed with PvvX and connected to HA? The PvvX docs only mention the Chinese model, but says it supports a few different hardware versions.

Cant confirm, but I've bought a couple from PB Tech, but most came from Ali.

I've checked mine and they all show LYWSD03MMC as the model, I dont know which is which but they do have differing text/label locations.

None show the NUN code.

Thanks. I guess they'll probably work then. I was just going to get a couple of extras in the PBTech Friday sale but wanted to check if they would work first.

Someone on the PBTech reviews said they flashed PvvX, so it's most likely compatible. I got one to try out. They're still cheaper from Ali Express, but the Black Friday price is pretty good for NZ.

I had flashed some of the older PBtech models. There is a Reddit article that mentions this

And there is an entry in the github issues where someone has tried it.

Given the price I'd grab one and try to flash it
