I apologise if this is the wrong forum, but I've got a bit of an issue I'm trying to resolve.
I installed Home Assistant a few days ago, because I noticed that the Fox mode scheduler wasn't doing quite what I wanted. I'm on Octopus Flux, and charge up my battery overnight, with solar to top up, then dump most of it at 4pm. However, if the min soc (40%) is hit before 4pm, it starts pulling from the grid, instead of using the battery to power the house, which sort of defeats the purpose. I understand the logic behind the setup, but it's not quite what I want.
I was reading into Home Assistant, and saw that predbat would be able to help here, possibly with some automations alongside, and would also use forecasts to make sure the battery is where it needs to be at 4pm, so I don't need to adjust manually every night. Great!
I hooked it up to the foxess cloud feed in the short term, just to get things operational and play around, and so far, so good.
I have a KH9 inverter, and just got an L charger installed. I was hoping to get the guys to install a waveshare rs485 at the same time, but we investigated, and it looks like they'd clash, because both would try to be masters.
Also, the L charger has an 8 pin male socket which just takes the entire com port over. We talked about splicing the EV cable and daisy chaining the rs485, but I didn't want to do that if the clash would indeed occur.
Has anyone tried this setup, and if so, is there a way to make it work? I've got to imagine it's possible on some level - I'd just like to understand how.
thank you.
