Control several Z-Wave radiator thermostats at once?

Setup, Configuration and Use Beginners

Hallo!

I would like to set up a simple control for my radiator thermostats in openHAB 2. This is my items/heating.items:

Group ALL
Group HEATING (ALL)
Group HEATING_LRK (HEATING)
Group HEATING_LR (HEATING_LRK)
Group HEATING_K (HEATING_LRK)
Group HEATING_B (HEATING)

I would like to have two switches:

  • Toggle thermostat_setpoint_heating between 17 and 21 for all members of HEATING_LRK
  • Toggle thermostat_setpoint_heating between 17 and 20 for all members of HEATING_B

For now this is all I want to set up. Would someone kindly give me a hand? The sitemap generated by Home Builder confuses me more than it helps.

Thank you very much!

You can’t do this for a group.
So create a virtual item for your temperature and add a setpoint in sitemap.
Then you have to write a rule to get triggered on changes to that virtual item.
Your rule needs to iterate over all group members and individually issues commands to each member.

Thank you, I could not figure this out from the documentation. I got it working now. OpenHAB has quite a steep learning curve until the pieces fall into place.
