MT174 monitoring

[dusk glen]

It has an optical port

from that you should be able to get a ton of info

here's two links to do some reading

from what I'm seeing it's quite possible

https://github.com/home-assistant/core/issues/37349#issuecomment-943602530 this comment is most specific to the meter and has a possible example but have a look through the whole thing (the issue itself slightly irrelevant as that specific integration doesn't look like it supports it)

But that kind of script you should be able to use with an ESP maybe and here's some examples from Tasmota (with your meter listed as an example)

https://tasmota.github.io/docs/Smart-Meter-Interface/

There might be other options out there too

Nice, thank you! I'll look into this when i have some time

never figured that the optical port was user readable

It looks like the best way to get all possible data

from the github issue there's more than 20 readings
