Power monitoring options

The biggest headache was waiting for Vera to reload itself every time I removed a node
I've just removed a bunch of devices from an old VeraLite, running UI5. On that system, at least, it allowed you to select the option to remove multiple devices before rebooting. But too late now!!

At this point, I've pretty much migrated off of Vera. It's kind of bittersweet.
Yes, absolutely. Feeling the same thing here, been running with them (or, rather, falling over) for around a decade. My current configuration is as described here.
The only thing left on Vera is now electricity meter readers, and I simply can't find any suitable WiFi replacement. Have applied for a smart meter installation and hoping that I can get ethernet access to the Consumer Device Interface.

My hem stopped reporting this august and I’ve replaced it with a Shelly EM. I’m using another one on my solar and they’re amazing fast to report and quite precise. They’re WiFi, and mqtt based. Recommended!

… that would be nice, but I need a “whole house” solution and can’t see that I can get this connected in to the main power feed.
I’m also keen to have a result which mirrors the actual utility meter reading.
But I’ll think this through again with the Shelly in mind. .
Thanks

I've been looking at this:
Expandable 6 Channel ESP32 Energy Meter Main Board
Introducing the CircuitSetup Expandable 6 Channel Energy Meter – the ultimate tool for monitoring and analyzing energy consumption in your home or workspace. This cutting-edge meter provides …
Trying to get them to answer if my 200A CTs will work with it, so far no reply. But it looks interesting.

Here is another interesting option. He says it supports MQTT though haven't installed it yet. https://lanternpowermonitor.com/

@akbooer they’re clamp based, so you could attach them to anything. As I’ve said, I’m into 9 months with Shelly em monitoring my solar and two for the main line. I’ve added them to my Vera to keep some automations regarding the electricity that I had before, but I’m using MSR for the logic. It truly was a plug & play change.
I’ve stopped to pollute my Zwave network with frequent updates and my mesh is more reliable. Give it a try: https://shelly.cloud/products/shelly-em-smart-home-automation-device/

You know I’m a Shelly fan! I am really after a total KWH reading, which you could approximate by integrating Watts, but it will always diverge from the actual meter reading. If I can’t find anything else (or get a smart meter) then I’ll give it a go.

I'm using an older version of this https://www.zuidwijk.com/product/slimmelezer-plus/ flashed with this firmware https://github.com/Beaky2000/esphome-p1mini connected to the HAN/P1 consumer port of the meter. The meter outputs data every 10s and the values are published over MQTT.

@akbooer in my case it’s really near the exact value, so I’m happy. I’m using influxdb to query and aggregate data. It’s more accurate than my aeotec hem. We don’t have data ports on the meter, so that’s the only way for me in Italy to measure kWh and watts.

Like @Crille I have an electrical meter with a P1 data port. I use a DIY ESP8266 reader that I described some time ago in this thread. Since writing my post I have changed the software on the ESP, the version I am using now publishes the meter data approx every 10s as a json.
A good wifi solution for the whole house if lacking a dataport is to use a Shelly 3EM. It is a three clamp meter that can measure all three incoming phases, assuming you have that. I have a few of these for measuring both single and multiple phase consumers, e.g. a two-phase water heater. It reports both energy, power, voltage and current per phase.
The only downside I can see is that the clamps are a bit big, so some space is required to get them in place around the incoming power lines.
