In case anyone reads old threads, it seems there are now 2 solutions to trigger the boiler heat demand.

One is to create 2 flows for each radiator. One that switches a relay connected to the boiler demand, when the temperature falls below the radiator set temperature (and the other flow the reverse).

The other solution would be to use the [VThermo app](https://community.homey.app/t/app-pro-vthermo), which is supposed to achieve the same without needing flows. For this, you would need to create a virtual VThermo and make sure relay is designated in it’s settings as a heater, and in the same Homey Zone as the VThermo and thermostat (e.g. Popp TRV or Aeotec multisensor).
