I setup predbat (batpred?) recently after hearing people rave about it for a while. Previously I was using target timeframes with a bit of rudimentary battery management to get through the day. It was a pain to get set up but I persevered because I heard how much people liked it.
Here's what has frustrated me so far:
- it's unclear exactly what it's doing or why - right now the dashboard says it's exporting to 25% but the battery is already below that and it's still exporting.
- scheduling loads other than a car is not possible. There are export triggers but what if I want to run something in winter?
- the car charging stuff is half baked if you are not using IOG. I want it to schedule the best time to charge, but all I can do is set a maximum charge cost which I can do with a homeassistant automation
- I have loads of sensors in homeassistant which would be helpful for the load prediction but I can't give it additional signals
- failing all that I just want a way to tell it to not allow the battery to discharge right now so that I can plug it into existing automations
- the entire interface suffers from the classic open source issue of the complicated parts working well but the simple parts being neglected. For a few days it was running an hour behind despite the timezone being set correctly in the config because the machine timezone was set to UTC
- the docs are a mess and at times directly contradict what I'm seeing in the interface
Maybe I'm missing the point, but is it really like this? I don't feel like I can trust it to manage the system properly
