What could be the reason when ruuvi shows quite weird negative temperatures especially in raw mode?
Example: in url-mode temperature is -3.0. Switch to raw mode and temperature is -131.51.
Also wondering why ruuvi shows only -3.0 or -4.0 when other thermometers at the same spot show something like -7 or -8. I opened the case but it didn’t make any difference in 30 minutes. Ruuvi has been outside for weeks, so it has cooled enough. I tried this with other ruuvi as well and the same thing. When temperature drops under 0, raw value goes under -100. I need to add 128 to the value? But it is still couple of degrees off.
When compared to other thermometers, positive values seem to be within one degree.
