The plugin transmits incorrect temperature data (humidity is normal) if I use external sensor. (without external sensor is ok) Log: "Sending temperature 642.51°C" Real temperature -12.72°C

Plugin v0.3.1 (2020-06-17) Homebridge version 1.1.6 Node.js v14.15.1 Npm v6.14.9 Raspberry Pi Zero WH Sensor IBS-TH1 with 1.7.0

Hi,

Uuups... Seems to be a problem with temperatures below 0° (which we didn't have till now in winter). Thanks for reporting, I see it here too.

Bugfix:

Open file \homebridge-inkbird-bt-thsensor\InkbirdBtTHSensorAccessory.js
Look for the line: self.fTemperature = self.cRawStatus.readUIntLE(0, 2)/100;
Change it to (delete the "U"): self.fTemperature = self.cRawStatus.readIntLE(0, 2)/100;

Should work. Soon - when I find a bit more time - I will release a new version 0.4 with the bugfix (and some new feature..)

Hope that helps.
