How do the elements of the NOW System communicate with each other?

The devices of the NOW System communicate with each other wirelessly, via radio frequency.
The devices that need to connect to the power outlet are the Connection Unit/Repeater and the Starter. Smart Valves and Smart Thermostats run on batteries instead. In addition, the Connection Unit must also be connected to the home router via Ethernet cable (included in the package).
Additional cable connections may be made in cases where it is necessary to connect the Smart Thermostat and/or Starter to the heat generator.
