Temperature precision #8

Closed reven closed 2 years ago

reven commented 2 years ago

Hi Andrew,

There seems to be some inconsistency with temperature measurements. I've built 6 sensors and the range of reported temperature is about 8C under ambient. These are all lying side by side on a table for 3 or 4 days now. Is the temperature measurement done by the E18 module? Or is it dependent on the firmware?

I am using zha instead of z2m, I don't know if that may also be a factor as there is no quirks file for zha yet.

The sensor version with minimal functionality used the built-in capabilities of the mcu to measure temperature. I knew it didn't measure well, but it was just a free option. At the moment, the situation is like this, the converter to z2m will be changed, the old version of the sensor with minimal functionality will send only soil moisture. Advanced versions of the sensor are equipped with digital sensors for temperature and humidity and illumination
