64A DIN Rail Relay

The Gruff DIN rail relay is a Wi-Fi device that lets you control electricity costs. The relay fetches Nord Pool prices daily from the server, and you can set the maximum price at which your devices like underfloor heating should operate.

  • Buy the Gruff relay
  • Set the maximum price and required operating hours
  • Enjoy lower electricity bills

Use for example for underfloor heating or other heating device control, or for car charging. The price difference compared to peak hours is about three times — no need to reduce consumption!

NB! Installation by certified electrician only.
