Perfect if you have a Vitocal 060-A boiler
Update: But i did manage to get in contact with the seller via mail and managed to make it work. It was network related. I coupled it with my boiler and now the boiler starts when I have too much solar energy.
Original: I ordered a smart meter, which did not work. I tried to get in contact with them. Only an email, no address, no telephone number. But, they do not reply to any mail. I do not know how to send back and how to get my money back.
