Everybody needs to get their energy consumption under control - Zemismart Smart Energy Monitor

- I started my Energy Management journey by consumption metering and its automation. But naturally, I quickly moved to finding better energy sources. And I have quickly learned that optimizing the consumption had a much bigger effect at much less cost!
I learned that when talking to a contractor who was selling a modern heating solution for my house, we reviewed my bill - and he confirmed that when I achieved is way ahead of what he could do with his solution - that is also very expensive.
And to optimize consumption, we need to understand it first - measure it. And this is not easy. recently, I came across a very clever SMART ENERGY MONITOR from ZEMISMART.
I have a number of energy monitoring devices in my house (some of them as part of the PV installation). The biggest issue have with them is, they are bulky and messy. The CTs are large, the device requires extra space in the switchboard, and there are lots of cables everywhere. Zemismart managed to integrate the IoT device inside a small CT. So it takes no extra space, it is simple and clean.
I even managed to put one INSIDE A WALL SOCKET!!!
So, let's get installed and integrated into my Home Assistant!

Nice video. Thanks.
Great video, I've got one of these sitting on my "to test" pile. These are very similar to the Schneider power tags series that have been around for a few years.
Voltage is usualy marked as U and U*I is apparent power (which should be marked S). Active power that you pay for is P=U*I*cos(phi). Anyway thanks for the tip to this little meter, will look to it.
seems like this needs to get built into every outlet in the future!
Vaclav you are doing a great job on your channel however the programming you show is a bit too advanced for me. Yes I know you said several times your channel is for advanced HASS users. Any way well done. ❤
Hi Vaclav, really nice video! Me personally I am not a big fan of Zigbee Devices with the pairing button hidden behind a socket. I had to repair a lot of my zigbee devices so often, that I don't want to have the hassle to open the outlets every time (I mean, let a professional come to do it) :D
To be fair, this is meant to be installed in the switchboard, then the button will be facing the front. I did install it inside the socket to prove it can be done thanks to being so small (as well as because I do not have each socket terminated in the switchboard).
@@bruxy70 that is true! if you have them installed in the switchboard they are really nice! If you have a stable zigbee network that will probably work too :D For me I just had to repair devices so often, that I don't want to have more devices that are also hard to access :D
@@tobiaslemann4974 You surely have a problem in your zigbee installation... As of today I have 90 zigbee devices in my home, I never have to re-pair it except two or three chinese devices in a year.
Octopus Energy in the UK will, on request, send you a tiny WiFi unit that listens to your smart meter and has a home assistant integration.
If they are able to identify the individual appliances from measuring the overall consumption, I'd be really interested to see how it works. I've seen some that do that, but I'd really like to know if that works.
@@bruxy70 Octopus Mini is based on total main metered electricity consumption, alas no granularity other than frequency.
