An easy and safe way to save electricity

The controller continuously monitors the real-time price of electricity on the market and provides users with an easy way to optimize the use of connected electrical devices during the most cost-effective times.

eFeeler is at its best, for example, in controlling electrical vehicle charging or use of hot water heaters.
