Domoticz

Hi all. I have a Raspberry / Domoticz setup at home and one at my summer house. I have used the home set up as a test lab. When the MySensors nodes work as intended home I take them to the summer house since I don't have that much time for programming, soldering and trial and error during weekends. However, few nodes seem to connect to the MySensors network at my summer house.

I'm using the same versions of MySensors, Domoticz etc both places. Are there any IDs or something which is "hard linked" to the home setup somehow and therefore refuses them to connect to the other installation?

All thoughts are welcome
