Possible bug with version 41rc1 and Winsen MHZ14A - CO2 sensor

[icnmfabro]

With the 41rc1 update, the Winsen MHZ14A - CO2 sensor always gives 0ppm as a result. is it possible to check the code if there is a bug on the new beta release?

I don't have Winsen MHZ14A connected to any of NAM, so this is a guess, but this was only change which could results in problem with MHZ14A. I did release 41rc2 it is on update server. In case 41rc2 does not fix that problem I'll connect MHZ14A and do some more testing.

Please close issue if problem is fixed with 41rc2.

No the sensor always shows 0 ppm and is not seen in the "sensor status" section

OK, I'll connect one MHZ14A and will do some tests

41rc3 - MHZ14A works for me: https://nettigo.aqi.eco/pl/sensor-2/graphs Data are somewhat low, but... it need some time to get autocalibrated or... I have damaged it connecting with reverse polarity 😕
Anyway - it sends some data - please verify on Your side.

It appears to be working correctly. Thanks for the support.
