Smart socket tracks
Nord Pool prices
The socket automatically turns your devices on and off based on the electricity market price. You set the maximum price — the socket does the rest.
🌿 Green hours
Socket automatically turns on during cheap hours, saving money while you sleep or work.
🚫 Red hours
Power is switched off during expensive peak hours, indicated by the red LED ring on the socket.
With the Gruff smart socket you can save money and maintain precise control over your home or business electricity consumption while reducing grid load during peak hours.
Feedback
I originally had 4 sockets and gave one to a friend. Not only do I recommend your socket, I give it as gifts too. Made in Estonia and very cool.
Erkki
Also kudos to you for the new app UI. Looks great and much more comfortable to use than the old version. Plus the Scheduling feature is a great addition!
