The HRA80 is a necessary component for the underfloor heating controller HCE80.
The HRA80 facilitates wireless communication between the HCE80 controller and the various temperature sensors and controllers in the different rooms.
If the HCE80 controller is used to control the underfloor heating in the evohome climate system, the HRA80 is required.
The HRA80 does not need a power supply, so batteries are not required.
