I see now were to report a bug. I will try to post this question there with a little bit more clear example.

Dear friends.

We have a house with BB
2x Evotouch each with 6 zones with distinct names
Synology
1x HGi80
2x RFG100
All works nice, but the Domoticz devices get mixed up.
Actual and set-point temperatures from BB and house are assigned randomly to devices.

Is there something I can do?
Maybe use 2x ...
