RFXrec433 and OS temperature accuracy lost

Why are the temperatures only accurate to a degree when the OS is reporting temperatures to 1/10th of a degree C?
This considerable devalues the usefullness when I've got temperatures that change slowly (like hot tub water).

Seems like perhaps the plugin is not calculating conversion to Ferinheight correctly.

This is the log output selecting ºF in the plugin settings:


RFXCOM Debug processing: 8 80 3 3 185 1 0 187 105 (08 50 03 03 B9 01 00 BB 69)
RFXCOM Debug Temp sensor 441 now 66.00 degrees and 0 humidity.
RFXCOM Debug Temp sensor 441 in list
RFXCOM Debug UpdateMinMax state temperature value 66.0
RFXCOM Debug check if new day: last date 2012/09/05, new date 2012/09/05
RFXCOM Debug UpdateMinMax state humidity value 0
RFXCOM Debug check if new day: last date 2012/09/05, new date 2012/09/05
RFXCOM Debug ++++++++++++++

This is the log output selecting ºC in the plugin settings:

RFXCOM Debug processing: 8 80 3 0 185 1 0 188 105 (08 50 03 00 B9 01 00 BC 69)
RFXCOM Debug Temp sensor 441 now 18.80 degrees and 0 humidity.
RFXCOM Debug Temp sensor 441 in list
Trigger Pond Temp Update
RFXCOM Debug UpdateMinMax state temperature value 18.8
RFXCOM Debug check if new day: last date 2012/09/05, new date 2012/09/05
RFXCOM Debug UpdateMinMax state humidity value 0
RFXCOM Debug check if new day: last date 2012/09/05, new date 2012/09/05
RFXCOM Debug ++++++++++++++

18.80 ºC = 65.84 ºF

Seems like the plugging is rounding up for the ºF settings. :shock:

That does appear to be the case; I have 4 temp sensors reading in Fahrenheit, and all four of them are showing xx.0 in rev 1.2.2... Looks like you round to the closest degree, then format the integer value to the nearest tenth.
