Highlander Posted July 11 Share Posted July 11 My now elderly ground source heat pump has no time-of-day controls, so I want to replace its breaker in our consumer unit with a wifi-controlled breaker, so that I can control times of operation to match a variable tariff. There are plenty at 63A advertised on Amazon & eBay, but I've not been able to confirm which (if any) meet UK regulations. Can anyone point me in the right direction here? thanks… Link to comment Share on other sites More sharing options...
JohnMo Posted July 11 Share Posted July 11 Go for something like a Shelly, buy directly off their website, save getting dodgy knock off. Link to comment Share on other sites More sharing options...
Highlander Posted July 12 Author Share Posted July 12 (edited) Thanks - I'd looked at the Shelly gear, but haven't seen enough reports about UK regs or quality - will look further [Update: just checked and remembered why I'd ignored Shelly - can't see anything in their product list with >16A capacity] Edited July 12 by Highlander further info… Link to comment Share on other sites More sharing options...

Use a normal smart relay to drive a properly rated normal switching relay. Leave the smart device to do low load switching. The switching relay can be either DIN rail mounted or in own enclosure.

That definitely makes sense, and assuages fears about reg compliance too Link to comment Share on other sites More sharing options...
