Which Solar system should I buy, can I get them in Openhab and how to read a old AC meter for Openhab?

I’m thinking about buying a balcony power plant. Currently in the short list are the Anker Solix 820Wp, which I could get for €375, and the Ecoflow Powerstream for €369. Both are without a battery, because I don’t know if it would be worth buying a battery - after all, it costs a lot of extra money. Furthermore I’m still trying to read how much my daily consumption is because the AC meter is very old and not digital.

I still have a few question and I don’t know if I need to open for each one a new topic. There are a few topics but they are old and it could be that there is something new

  1. Is there a (un)offical Openhab binding for one of them and how can I get it?
  2. My "I currently have an “AEG AC meter Form J14H” from 1967, which is an electromechanical Ferrari meter. Is there a way how to get a digital number in Openhab so I can see my daily consumtion?
  3. Does anyone has experience in solar plant and can recommend me one or should I do a DIY solution?

In additon I am living in Germany and paying round about 44ct/kWh.
Also, my english isn’t so good.

Thanks for reading this and trying to help me.

Instead of buying a specific solar kit that integrates with OpenHAB, buy a meter that will :wink:

Thanks for your reply, is this thing for the power outlet or for the AC meter?

If it is for the AC meter there are some problems:

  1. I am living in a rent flat.
  2. The powerbox where the AC meter is, is so far away that the Wifi is extrem bad.
  3. I am not into electricity and don’t know if it is legal when I change the setup in the powerbox so that die "Shelly fit in.
  4. Why pay extra 70€ for a Item that maybe isn’t worth.

With the last point I mean that maybe when I install that thing and register my solarsystem. Then the electricity provider comes arround and change that thing to something that is digital. Because that thing maybe goes also in the opposite direction.

If it is for the power outlet on the solar system:

  1. Why spent 70€ for something you could maybe avoid.
  2. Isn’t it maybe cheaper to buy a smart power outlet for outdoor? Or they don’t work the opposite way?

Again thank you for the idea and I will think about it.

Only you can decide if it’s worth it or not for your use case :slight_smile: im not the one who will justify that for you. Yes a Shelly plug will work - if your solar balcony has a plug, if it doesn’t then it won’t.
The Shelly em I linked requires no major wiring. The clamps go on top of the cable you want to measure and the rest isn’t too overly complicated. One Shelly em with two clamps can read both production and consumption,

If this is beyond your knowledge, you either:
A) learn.
B) hire someone to do it.

As per usual :slight_smile:
