People who have #selfhosted #solar monitoring setup, what do you recommend that’s relatively easy to set up and can show history/monthly trends?
The ‘cloud’ functionality of my inverter is no longer available and it'd be good to keep track of all that.

@wally3k Shocking! I don't have solar myself but I believe there's quite a lot of activity in monitoring (and controlling) inverters using #HomeAssistant
You might have to be more specific about the inverter make and model though. It's a bit vague right now 😁
Anyone out there able to help Wally with info about using HA to talk with solar inverters without needing them to be online?

@PossiblyMax it's a Zever inverter that has a fairly easy to parse text stats page, so I'm not too worried about actually integrating it.
I hear HA has a pretty steep learning curve though, so it'd be good to have a few options 🙂

@wally3k Hmm I guess depending on how deep into home assistant that you want to go, it can be a lot 😁
But it's simple to get off the ground and easy to throw away if you don't like it. Depending on how your inverter can be integrated it might need something custom but again it's not something I have been lucky enough to need (yet).
It might be a bit eye opening on startup where it detects everything it can integrate with on your network etc! 🤣

@wally3k same problem here when my inverter company went bust (Enecsys).
I went for Domoticz and some custom code to simulate the cloud API locally, which was originally intended to work with pvoutput.org. Simple to then shove the numbers into Domoticz API and it does the rest (history, automation, etc)
Here if it's useful:

The code can also shove data into local sqlite db if you like.

@wally3k I can recommend the „volkszaehler“ integration. Although this is a pretty German word, you can integrate a lot of stuff like smart meters, gas meters and even your water meter. It counts „zählt“ nearly everything and shows it on a self-hosted web page running on raspberry pi.

@zvenster Very interesting, thanks for the suggestion! 🙂
