Three-phase installations

[neo2angel]

Hi everyone
I have flashed my emporia with the code, it seems to work fine, but reading the code only shows Phase A and Phase B.... and those of us who have 3 phases, how can we do it?
Thank you very much

[flaviut]

Copy-paste, basically! In the config,

• add a new entry ("phase_c") under sensor -> phases, using an existing phase as a template
• add a new entry under sensor -> ct_clamps, using an existing phase as a template
• update "Total Power" to include the new phase: return id(phase_a_power).state + id(phase_b_power).state + id(phase_c_power).state;

and of course you need to assign the circuits that are on that phase to that phase.

OK thanks... I'll try to see how it goes

Ok i went through this myself and i'll add it here. Do make sure to change what clamps you want to be tied to what phase, my sketch kind of goes 1, 2, 3, 1, 2, 3.

I'll also add that the front page guide was kind of missing important piece for someone who doesnt do stuff like that regularly but is able to follow guides. There's no vue2.yaml file in this project. But the guide tells you to run "esphome run vue2.yaml"
Leaving this here for someone who tries to do search on this.
Example sketch should be saved into file like that into project folder and edited for your specific parameters on wifi etc. Easy step for integration is to make new device under esphome in your HA build, name it emporiavue2 and then esphome makes the device and you can take the api key stuff from there.

Edits are always welcome :)

But I think I've improved the wording a bit. Can you check and let me know if that's better?

Hey, thank you for taking a look :) I'm a git noob so I dont really know yet how to propose edits officially.
The update is better, because it doesnt presume having a file and makes reader to think about where the file should come.
I'd maybe propose one more edit, before the code example:

Here's a starting point for a configuration:

Great suggestion, updated! Happy to accept suggestions in the discussions as well, for folks who aren't familiar with github.
