MJWSD05MMC only shows Temp: 0.00°C, Humi: 0.00% #492

Hi,

I have a MJWSD05MMC that I (finally - it was very very hard to get activated, pure luck it seems) flashed with 4.7, but it really only shows 0.00°C, Humi: 0.00% as shown here after connection:

Any input to what could be going on here?

PS. I have another MJWSD05MMC (and a bunch of LYWSD03MMC) that works fine connected to home assistant.

There have never been any problems with the MJWSD05MMC. Why did You flash the firmware from LYWSD03MMC in MJWSD05MMC?

Hmm...I wonder how that could happen? Where can I find the firmware for MJWSD05MMC for manual download - then I can try to flash that one.

Didn't TelinkMiFlasher.html offered this firmware after activation?

So I have not done anything manual - only used the Telink flasher. I cannot remember why it might have flashed the wrong LYWSD03MMC firmware, but as I said - nothing manual from my side - hence, I can only explain it as the flasher must somehow have presented me with the wrong firmware.

Anyway, I downgraded the FW to the original firmware and managed (after a few attempts) to activate and flash the BTH_v47.bin firmware.
