Exchange electricity spot price saving tips for winter

Exchange electricity contract holders can now take advantage of Nord Pool's hourly exchange electricity spot prices with Cozify automation: schedule the use of heating/charging devices for only the cheapest exchange electricity hours of the day, or avoid the peak operating hours.

Note: Controlling exchange electricity according to hourly prices requires an activated Cozify Premium -service (9.90 €/month). The new Premium service replaces, and also includes, the previous subscription Camera Service, as well as historical data.

How can I save on my electricity bill?

Water boiler

The water boileris heated simply using a power supply. Add a smart plug to the water boiler's power socket and Cozify will use this to control the power supply to your boiler.

Underfloor heating

Electric underfloor heating

If electric underfloor heating is powered via a dedicated fuse, it is possible to control the current of the underfloor heating with Cozify via a smart relay installed on the electrical panel. For small sites with just a few fuses, Cozify recommends the Develco A16 relay as a smart relay.

In larger detached houses, a smart relay should be implemented through the FutureNow FNIP relay pack.
