Esphome + SCT-013 - sensor not showing up in Energy Dashboard

ESPHome
1

I feel like I’ve looked at every tutorial out there for how to set this up so my SCT-013 sensors will show as “Grid consumption” sources in the Energy Dashboard, but I’m obviously still missing something because they won’t show up in the list despite an evening of troubleshooting and being fairly positive I’ve set everything up as per another tutorial that does this :confused:

Does anything jump out at anyone with the below config? It’s turned into a hodgepodge of a few different tutorials at this point unfortunately so I’m not opposed to major changes if needed anywhere.

What does the kWh sensor look like under Developer Tools – States?

By the way, I’d highly recommend going with a PZEM-004T instead of just a CT. It will give you a MUCH more accurate and meaningful measurement (plus a lot of extra useful info about your mains power). And it’s pretty inexpensive. I have 2 (one for each phase coming into my house) and have been very happy with them.

Here’s a snapshot of the states page:

Thanks for the tip on the PZEM approach! I had seen some of those in tutorials but always with the closed ring, so I had ignored them as an idea as I don’t want to have the meter to the house pulled to install it. I just did more searching and realized they also make a clamp-on style PZEM. I will be ordering a couple this evening after work now! Gotta love starting Phase 2 before Phase 1 even goes to production haha

I don’t see any red flags with the states view. I had a similar weird issue with my gas meter; ended up using a template sensor to get around it. I ultimately figured it out months later, but I can’t remember what the issue was. Ha

Here’s the exact one I bought (obviously there are cheaper ones):

It was pretty easy to setup, but feel free to reach out if you run into any issues.
