I'd hoped I might be able to use my Eddi diverter to monitor the energy going out through the heat pump breaker box but it seems that the 'monitor' option for a CT clamp only gives a live energy use view on the Eddi screen itself and has no logging or display through the app. Setting it to 'AC Battery' or Generator' messes with all the other logging so that's not much use. So I was wondering, as there's a slot spare in the breaker box, could I just install a single din rail energy monitor in there and have it record total energy usage? Anyone used one of those?



Would be cheaper than getting a wireless energy monitor setup as they seem to be quite expensive. It won't give me the detailed display of what it's using and when but a total over time would probably do what I need.

Something like this?

Yes.

I have 4off SMA GTI's and on the DIN rails i have mechanical counters and a little LED that flashes.

Great, thanks for the confirmation

Well, I should have taken more notice when they installed the heat pump. In the cupboard that houses the pump outside, there are disconnects for the heat pump and the immersion feeds and a separate breaker box from the one in the house. When I looked more closely this morning, what I thought was a pair of breakers was actually a breaker and one of the meters I was going to put in the other breaker box in the house. So, all I have to do is just read the meter when needed, which is handy
