Temperature differences : calibrating senors in Domoticz ?

[flotheouf]

Hello,

I have bought both Lacrosse and Oregon scientific temperature & humidity sensors, and my sensors are catched by a rfxtrx433e connected to a RPI with Domoticz on it.

I find discrepancies of ~0.4°C between some of the sensors ; is there a way to correct the values in Domoticz , like adding an offset for a given temperature sensor ?
If I go to "Edit" on my sensor, I can only change the name...



Thank you very much for your help

Do you not have this for "Edit":-?

0.4 is well below their expected accuracy, even original calibrated DS18B20 sensors have an accuracy of only 0,5 degrees.

Hello,

Ok my mistake, I was looking for this option in the "devices" tab...

You mean that the Oregon's sensors are based on DS18B20 ?

I just want to try to homogenize all my devices before using them

Thanks,

Florent

No they are not based on those sensors but to give an idea of the accuracy of a good sensor.

You can add an adjustment value but this is just a fixed offset, it cannot improve the accuracy of the sensors.
