32A Power monitor that works with HA

Anyone got ideas on what works well for monitoring large appliances.

Looked at emporia 16 channel. Too big to get all that in the CU.
I'm looking for something I could chuck under the floor boards or behind the cooker.

Monitor ASHP power, either CT or some better smart wifi meter to replace the provided kWh meter. Has flashy led, so could use that maybe.

Monitor electric cooker. 32A circuit

Immersion , iBoost. 16A circuit. Maybe the GivDivert will fulfil this one, once issued out.

Kitchen stuff I've got single plugs for already

Laundry I've got 2 x Knightsbridge double socket with energy monitor. So 4 items merged into 1 entity laundry.

TheDragon (GivEnergy) I see Chinese wifi MCBs but these are just switches and no overcurrent so ruled them out

I know something that will work. https://uk.rs-online.com/web/p/energy-monitoring-devices/1348659
But will also need a wireless gateway and a way of reading modbus.

But is all very expensive!

I use one to monitor my hws diverter. But it didn’t cost me anything

Was also thinking of ripping the guts out of a Gosund plug. Hopefully the CT is an actual coil I can pass the 6mm live through.
Mount it in a small box under the floor.

Basically cut the ASHP cable. Then join back together with 3 way WAGO 32A joins.
Tap off L+N to power the plug. Then thread the feed through the CT.
Ignoring the actual switch and relay as these are only 16A rated just using the monitor bits.

For a fiver may just do what I need.

May work.

Shame these darm plugs are moulded and not easily opened.

TheDragon (GivEnergy) Shelly Pro 1 would do what you want. https://shellystore.co.uk/ But it aint a fiver!

anglefire contractors are 16A.

If I was to switch it, would need 32A.

Hence the passive butchered monitor plug idea

TheDragon (GivEnergy) Ah that's because I linked to the wrong one! https://shellystore.co.uk/product/shelly-em-50a/

This uses a CT rather than being whole current. It can switch a very small load - so a contactor.

anglefire similar to the 8 way emporia. But shelly at least has good HA integration.

Shame they dont make smaller CTs.

If they were half this size I could get them side by side in the CU

TheDragon (GivEnergy) I'm not sure of the spec of the CT's - but I suspect they are standard 1:50 or 5:50 (for the 50A one) and therefore any off the shelf one would work which you can get small ones.

anglefire

Argh ok, that seems a workable plan, instead of mashing up a few monitor plugs
