Negative temperatures about atc_mithermometer HOT 10 CLOSED

Added support for up to -9.9°C now :)

from atc_mithermometer.

README.md still says "Byte 11-12 Temperature in uint16", I guess that's not correct anymore?

Disregard, I misread that.

Sorry, it says:

When looking at the specifications this LYWSD03MMC Sensor is specified from 0 °C to 60 °C. The LYWSDCGQ (the Bluetooth Temperatur sensor with the round display and an AAA battery) is specified from -9.9. I can confirm this sensor also goes down to -9.9 °C. At colder temperatures it only shows an "L".

I think the this refers to the LYWSD03MMC indeed. So we should try that.

Oh you are right. Never tested it. Will look into it.

Thank you

Worked down to -16°C even, let's hope I can revive the display. :p

Yes in theory it can meassure lower than -9.9C but it simply can not display then anymore :)

Its seems to me that your one has some fault as i didnt got any one that has this problem even after leaving it outside and having it in the freezer for a while

Yeah, this one came back fine. :)

Would it be possible to switch display to "precision of 2 and a scale of 0" below -9.9 degree?

For example, -11.3 cloud be displayed as -11? BTLE data should advertise correct value -11.3.
