Can the Emporia Vue 3 measure usage for 240v split phase loads (240v U.S. loads like AC/dryer)?

Yes. You can put a CT clamp on both phases and then combine them in the app, or if you know the loads are balanced you can just put CT clamp on one of the phases and then use a multiplier like 2x or whatever is most accurate. This is what I’ve done on my setup

and it will work with double pole breakers like ac and dryer are on?

#

I got a Shelly EM but didn't realize it would only work on a single phase and it won't work with split phase (the double breakers)

If the dryer only uses 240V and not 120V, you could use the Shelly EM if you don't connect the N. Shelly 3EM does work.
