Could you share how do you combine the hourly cost with wattage readings?
kwh x $ Price is generally a dollar figure for 1000W per hour.

I gotta chime in also. I just learned about your channel literally today when a buddy DM'd me a link on your YouTube homelab tour. We have pretty similar interests. I also have an IOTAWATT and I love it. My only grip is I wish they had the ability to log more channels with the same unit. ie Approximately 30 channels.
Sweet! Yea, I have several panels that have 2 of them for that reason. I have debated making a larger one since the code is open source. It would be great to have one that has more ports, and perhaps the ports combined into less cables.

The main one I'm away of is IotaWatt, which I've had running in my panel for the last few years without incident.
Eh, that's even more expensive. I think I'll end up having to develop my own hardware, even with Vue blowing $1500 for energy monitoring is a bit too much given how cheap the hardware can be.

You're running all your flat's power through that $14 Chinese rubbish and never assumed that shortcuts were taken or quality would be an issue? How do you know it will continue to function as a circuit breaker and isn't just a piece of wire inside? For the uninitiated, CE marking is meaningless (it allows for self-certification). I'd like to see Big Clive do a teardown of one of those.
There are 2 ways to design these. They could use a regular relay, or they could use a solid state relay. Solid state relays have widespread fraud. Like 60% of the ones on amazon will catch fire or fail before they hit the rated current. Trade suppliers generally don't sell them at >30 amps. Regular relays up to 10 amps are cheap and reliable. Beyond that, they get expensive surprisingly fast, and the reliability is h…

I've been down this road quite a bit on Amazon, eBay, and AliExpress/Alibaba. Are there any good options for relays that work for 100-200amps? I've found 30 amp relays of the type that are built into PCBs and I have tried a few 100 amp contractors that can be triggered with a separate line but I'm not sure I trust them. Most tend to top out at 65a rating and I get the feeling the 100a ones are just the same but with…
It's very common to use a relay to control a contactor.

I had four tasmota preflashed athom plugs die on me in less than a year. As long as they worked they were perfect but they don't last... Hope they addressed the issue meanwhile
Were you switching high loads? I've had a few for some years with no issues
One step further. I just installed the Emporia Vue 2 in my distribution box. 16 CTs plus the three mains phases. It's ESP32 based and there is a great ESPHome project that you can flash it with for local only reporting. Add some HA and VictoriaMetrics, and now I can see how the whole house behaves with Grafana. Next up, Zero-Export using this data to steer my little OpenDTU solar plant. We live in such cool times!

It's crazy to run any power through that. Only safe option are current transformers
Do you have any you would recommend? I'll love you for a link, and like you for a brand name. Not being a dick here, I'm genuinely looking for one that I don't have to lose sleep over installing.

You can do mains only or every circuit

Why not just use a current transformer? (Clamp over wire type) It's much safer.
> Why not just Please learn to never use this type of phrasing when offering suggestions. Your entire exchange was needlessly patronizing and off-putting.
Maybe just something about the latter being interpreted as a question, and the former being interpreted as an order.
I got a Zigbee power breaker and hooked it up so all my flat's power goes through it, and then made an e-ink display to show my power consumption: https://www.stavros.io/posts/making-the-timeframe/
For people in The Netherlands: all Smart Meters that the net maintainers installed (are required to) support the P1 standard, which provides a standardized interface for customers to read out current current draw, cumulative power use, etc. Usually gas is hooked as well. You can hook up a cheap dongle to expose the stats in an app. For instance, we use: https://www.homewizard.com/nl/shop/wi-fi-p1-meter/ This meter al…
