Energy meter everyone needs

I'm so glad I purchased the Shelly EM.
It can monitor 2 circuits simultaneously. I have one after the main isolator and the other after the isolator for the ducted airconditioning main supply.
It's a small apartment so have them both with 50A loops

Realtime monitoring is great. Was also so easy to connect to home assistant.
It's a great purchase.

Also thanks to Oz Smart things for shipping them quickly in very sustainable packaging.

Shelly EM

Very happy with the Shelly EM, it gives you real time readings and total kWh used, there are also additional features of which I’m still reviewing
In summary it’s very good value for money, I ordered an additional CT, One (120A) measures Total Power for the house and the other (50A) measures a sub-circuit.
Love it!!
