Shelly 3EM or any pulse meter reading.

Since this just popped up again, I will say if you get the new slim power monitoring plugs from bunnings, check them out before blindly trusting them. Voltage numbers are all over the place on the ones I got.

PolicyGuy:

That must make for substantial differences in device signal recognition for the device power consumption monitoring widget.

neb:  I first read about it in an EE journal and it didn't distinguish between US and non-US disaggregation, I'd have to dig the journal up again but at most it'll be different training data. I was actually surprised to see real commercial products that implemented it on the market because the research seemed rather academic at the time.

On the market doesn't mean that it works well or at all. With everything being a computer they can just promise that it will get better in a software update and the suckers I mean users will hang onto defective things vs returning them.

With almost everything in the house now being switchmode with motor things being inverter that ramp up and down as needed, I expect the only thing it would reliably be able to report on is the hot water heater. 70+ other switching power supplies plus all the wifi lights and other stuff all running at  the same time and tell them apart? Not likely unless some of them are spewing out masses of harmonics because I have ripped the rifa cap out of the power supply before it decides to detonate itself.

Anyone gone down the DIY RPi route for optical pulse monitoring from a smart meter? This sort of thing.

Nope but ESP32

See my reply at the end of the last page. I used ESPHome combined with Home Assistant for this.

Thanks - having no previous experiance with ESP32, I take it that it's USB powered and communicates with HA via wifi? Then run HA on something like a Pi / Docker container etc?

Yeah so long as you have a smart meter with pulse outputs then it's fairly trivial to get an ESP8266 with something like ESPHome running on it to count the pulses, convert them to power usage and send the values out to something like Home Assistant.

My biggest challenge at the moment is getting 5V power to my power meter for the ESP8266 LOL....
