I think I read that a Smart Plug solution is incoming, which will integrate with the the inverter, and portal. Is there any chance these might come in a CT clamp flavour?

We're getting an Air Source Heat Pump soon, so my use case is being able to monitor the demand from it. (not all appliances are things which plugin via a three-pin socket, electric ovens being another example.)

adamdoran add an extra EM115 in the consumer unit.

There are lots of solutions for metering separate circuits. Some are bloody expensive- but really good. Some are cheaper but have some things wrong with them - installation is difficult or needs more stuff than you think at face value or aren’t very accurate.
Shelly do a lot of good kit but in some cases you need some sort of box to house the kit. Including ct clamp type meters. Not as cheap as an em115 necessarily but is easy to integrate into home automation systems such as home assistant or just it’s cloud service.

stevelewis and have it connected to the hybrid inverter? Does that know what to do with multiple CT inputs?

anglefire thanks, I've heard of Shelly, and a colleague mentioned they had their home fully wired using KNX, which sounded like a very expensive solution. More research needed! Cheers.

adamdoran I understand the GE team is able to add the data to your dashboard.

stevelewis very interesting. I'll ask them about this, as I'm currently discussing some details related to our upcoming inverter upgrade (HY3.6 -> HY5.0 Gen2).
