Hi all, I recently found this interesting product 6 CH Energy Meter Made For ESPHome.
I live in Europe with 3 phase electricity entering my home. I was wondering whether this device is capable of measuring 3-phase electricity, like the Shelly Pro 3EM.
Thanks in advance!
You can kind of get around this by re-writing all the yaml, as by default the Athom yaml assumes all the CT's are being used to monitor circuits on the 'inside' the house, and iirc adds sensors that sums up all the CT values to show the entire load.
Here is a yaml that I wrote for a friend who has 3ph and bought one of these units. You'll need to update the subsitutions to reflect what each CT is used for (i.e. CT1 relabel to 'Lights Circuit' etc.

Ok, I will. Thanx for confirming :)
Yes, it can. You just use three clamps and measure all three phases on their own
Hi, Good point, never realized that. You mean when I measure for example the 3 fases of my carcharger, I posibly get wrong readings? The app and car shows 11 kw charging, the Athom shows resp about 3.4, 2 and 2 kw = 7.5.
I bought 2 of them. Can I get around this by buying a third and use 1 Athom reader per fase?
No, it can only measure single-phase electricity (one voltage)
