Anyone doing any non-cloud based power consumption monitoring? I've been looking at various options for CT clamp based solutions (looks like Shelly does an off the shelf solution that would work but it is on the pricier end of the scale around £60) but was just wondering if anyone was using anything specific!

This is the one I am looking at.
I also use TP Link P110 energy monitoring plugs and some custom config.

Exactly what I use. It's really good. Updates fast and integrates into MQTT. Instant power usage updates every few seconds too. I also have a couple of TP link plugs for monitoring specific items.
Away from home currently hence the low usage.

Can you not just login to your electric account and view the data from your smart meter? Or do you need it more granular than that?
You can do that with the Hildebrand Glow integration. You can allow them access to your smart meter data. It works but it's nowhere near as granular as their IHD with MQTT, plus there's no power usage reading.

Yeah, I've had a look over that but wanted something a bit wider for the whole house. I've got plenty of dumb devices that are going to be chewing up power!
Same on the plug front, I've got some energy monitoring plugs but generally use those for monitoring devices that have gone down (such as a dumb dehumidier that has filled up and needs emptying)

Why don't you get a smart metre then? surely that'd do most of what you want for free with the benefits of a smart metre on top?
Issues with stone house construction! I was also not happy getting one of the SMETS1 smart meters as I did move suppliers a lot. Whether or not the SMETS2 are better for signal, it's nice to keep things locally rather than having to rely on too much cloud communication for the home automation bits.

What custom config do you use, I tried the P110's before and they were rubbish, even with an AV receiver that never goes below 30w draw after an hour watching a movie loudly and it getting up to 90w it said the highest peak was 29 and after an 8h gaming session with it plugged into a dumb meter it was 500w below on total energy consumed.Display and CAD - Smart meters

I wish there was something that read power like the dumb energy meters but were wifi.
Ive been looking for something local since moving to solar which made my IHD useless lol

Given the cost comment, I’d imagine this is a no-go (£86). However, I use https://openenergymonitor.org/ for electric use, solar pv and heat pump monitoring. They all work really well, come with basic UIs to see graphs & delve into detail and you can easily pass the data into home assistant.
Looks good, don't mind paying out if I'm getting something decent and well thought out for it. From what I saw of the shelly one, I could replicate with something homebrew for a sixth of the cost. I will keep this on the shortlist - tah muchly.

I can't comment on accuracy, but I just wrote some basic code that multiplied usage by time of use rate (as p110 app didn't support it). I was measuring oil heater versus central heating efficiency for home working.

sweet mother of jesus on their emon with ct clamps
Barebones £85
UK plug £143
Only 50amp ct clamps added £220
+£5 on top of 50amp cost if you want 100amp ct clamp
Looks like the kinda thing I would have bought but looks to be sold out. I've bought a few things to hopefully roll my own using an esp8266 and a clamp so will see how accurate that ends up being! Hopefully I can calibrate it using an energy monitoring plug...
As an update to this, I did end up making my own based on a project that I found out online. Got something up and running and seems accurate enough for my purposes (aka not 100% and seems to have a 30W flutter at points but good enough for rough gauge of house usage). Got the CT clamp around the mains incoming live and getting some reasonable results out. Only downside is now I know that the base background power usage of stuff in the house is about 450w - ouch! Just need to make a home assistant sensor to calculate the ongoing kwh usage for the energy dashboard charts.

Still interested to know why you didn't just get a smart metre instead as that'd have been free and been even more accurate?
But i had a similar surprise when i got my smart meter, our house was sat at around 400w idle so after a bit of poking around i got it to about 130w.
