Hi,

After the OpenTRV/OEM hackathon I updated the firmware on my Rev 2 board.
After that it looks to be reading ~2C higher than the emonTH I have in a
similar location where as before the update the temps where approx the same.

Have a look at

.

I updated the firmware to the latest Git on the 24th Feb, if you check the
temps befpre that you will see that 'Office Temperature' (the emonTH) and
'Office Temperature OpenTRV' are more or less the same (ignore Soil
Temperature this is a temp sensor in a pot plant and expected to be a few
degrees lower). After the 24th, Office Temperature OpenTRV is consistently
a few degrees higher than the emonTH. To the best of my knowledge nothing
has changed other than the firmware.

Let me know your thoughts.

Jeremy
