Patch:
- Based on #85 and Z2M 1.22.1-1 there was a min and max limit of local calibration of -6 and 6 so we limit it too, also the default calibration is round to full int instat of two dig float, but only temporary it should be changed in Z2M Z2M#3488 and PR#3491
- Change the startup process to fix #69
- Change the nighttemp task #84
- Increase the precision of the shown temperature to 0.1 thanks to @Cycor
