Monitoring power usage

Hardware
1

Hi there!
I’m looking for an idea to monitor the power consumption of my minipc with HA.
But i dont want to use smart plugs or sonoff.

Any idea?

i am now planing to do some scripting and use RPI with custom board for 3phases
100A noninvasive sensor - SCT-013-000

If you don’t want to use a smart plug then you could use one of these boards …

Obviously you would need to also provide a D1 Mini with ESPHome and a SCT013 current transformer.

Will give you more information than just sticking a current clamp on the analog input of an ESP8266, more accurate and more reliable.

I am trying to integrate the CircuitSetup 2 ch unit into HA with ESP home and can’t get it to work. Do you have a working unit? Can you advise on how to use it with HA?
Tnx

I don’t use ESPHome, but have you checked the documentation?

Looks like the docs show all the connections needed as well as the YAML config.

What is the problem you are having?

I can’t get CircuitSetup 2 ch unit ESP 32 to join my network. I flashed ESP32 with
yaml from CircuitSetup

and
Digiblur

and can not get it to communicate
Home Assistant running on RPi 4 under Docker / Portainer
Flashing ESP32 with ESPHome Flasher via USB
The log looks good from USB serial port after flash but
doesn’t connect wifi to my network and Home Assistant / ESPHome

I don’t use Docker, Portainer, nor ESPHome so I’m not sure I can help.

But why are you copying config from other people, and not the documentation? The danger with using someone else’s config is that sometimes there are code changes which may invalidate that configuration. The docs should always be correct.

You also didn’t post your config, but instead theirs. If I had to guess, if it doesn’t connect to your WiFi, you would have something wrong in the WiFi section of your config.

What do you use to display the data from your energy meter?

Well, this probably won’t be much help but I wrote my own firmware as I build a device based around this board with an STM32 “Blue Pill”, ILI9225 TFT screen and W5500 Ethernet module.

However, what I can suggest for you is to start your ESPHome configuration from scratch. Don’t use someone else’s.

First, create a minimal configuration that just connects to WiFi. Does that work?

If not, then simplify the WiFi setup as ESPHome has some issues with special characters and such in SSIDs and passphrases.

Create a network “test” with password “test123456789”, WPA2.

Try to connect your ESP32 to it. Does it work?

If so, switch back to your regular WiFi. Does it work? If not, then something is up with your WiFi.

If it does work, then add the power monitor.
