RFXcom sensor ID changes

Post by Umberto » Saturday 03 March 2018 11:23

Hi All,

I am a relative noob with domoticz and have just installed it on a RasPi2.

As hardware I use (among others) a RFXCom device to receive temperature sensors combined with humidity. I noticed that the sensor changes its ID when the battery is changed.

Is there any way to avoid it as being defined as a new sensor (I want to continu the measurement serie I have)? This is not a problem from Domoticz, it is due to the sensor that changes its ID.

Maybe I did not search the forum well, but I couldn't find any suggestion how to avoid this.

Best regards.

This is normal behaviour

No, but you can move your old sensor data to the new ID.

Hi SweetPants,

Thx for your very fast answer. I will give it a try. Sorry that I missed your reference. I will give it a try the next couple of days (when the batteries have died). I knew it is due to the sensors, but didn't know how to avoid the loss of data. Many thanks again.
