I believe this is it: https://emporia-vue-local.github.io/docs/tutorial/intro/
It's been a little while but I did follow a guide for the emporia vue.
There are newer versions and other similar brands out there if I find the guide I used it will be fairly specific to this hardware (certainly the base code setup)
I will look tomorrow
I have two 150a panels in my house and I have 2 emporia vue 2's one on each panel. I reflashed them with esphome so I own the data, it's not going out to emporia. but they work as individual devices collecting data from the clamps.
For non 240 loads you could also use smart plug with power consumption if you're just wanting to track that device. In my use case I am capturing all usage from the two big clamp at the top of each panel then each clamps usage which gives me an 'untracked' value also since I have more than 16 circuits in each panel I cannot track every circuit.
The CT clamp reads the current without having to be directly connected to the wire. It just 'clamps' onto the leg and is non invasive. https://en.wikipedia.org/wiki/Current_clamp
Here's one of my panels with the clamps on. The top clamps read total power, the individual clamps below are reading one leg each. for a 240v you need both since each leg is only supplying 120. My dryer also sometimes only uses 120v when it's not actively heating.

I have a couple emporia vue (2's) and for my electric clothes dryer I just use a CT clamp on each leg and sum them.
Within the vue esphome config:
# Combined Dryer Sensor
- platform: template
name: "Total Clothes Dryer Power"
id: total_dryer_power
lambda: return id(cir9).state + id(cir12).state;
update_interval: never
device_class: power
state_class: measurement
unit_of_measurement: "W"
filters: *throttle_avg
I paid $99 for one on 10/25/25 from microcenter
There is a community here, maybe I need to try to get people engaging in it, starting a game thread etc...
Actually, in my case reddit forced me to obtain answers without visiting the site because it is hostile to me... I'm clearly in the minority along with you all :). But, while I'd love the real users there to move here, reddit the company can rot.
Making me log in, to view anything will just further remove my eyes from anything created there. I only visited a couple subreddits (primarily my local soccer team's game thread) to view the comments. Since I deleted my account 3 years ago I guess I'm going to miss out on that.
I'm tired of winning boss
Hrm... Hadn't seen it will check it out
I'm slowly trying to untie myself from google. Most recently disabled Google maps because of their renaming stuff that shouldn't be.
Tomtom is working for me for now, I hopped around to a few different nav apps but landed there. Tried a few osm based ones but they were all pretty rough around the edges, middle and centers.
Twas, but a joke...
It's insane for a product whose price has gone through the roof before the ram shortage
