@hbpowerwall have a diversion installed but its installed on a grid-tie system if not mistaken.

I linked the rasp above. But it can be replicated to an mcu. My esp8266 project to mpp can be converted to controll output but it Will demand coding skill :)

Correct that basically sitt in between. :) But as Said think twice. IF you aint going grid an Arduino can do the jobb with some relays :)

Just hook up a unit that monitors output properly and then engage 1 or 10 relays/ssrs for powering external heaters or what not. Get alot small ones like 1kW each so you can vary the load based on what you got You can add a diversion unit instead that do it. Switching over the pv to other unit...

The inverter cant do what you want. You need external logic. Element is on/off so you need to have many elements or never start it until you have full sun. Like ajw22 wrote. Like for instance the sun outputs 5kw and you can then have 4kw of elements active. and so forth. Unless you bypass the...

Then it will work fine. WatchmonUdplistener is already dockerized so you can just install it. Note that it need to run in network host mode

The difference at the nominal voltage is more critical than during the end points. So at 4V+ its not a problem with 0.2v difference to be honest but at 3.6-3.7v it need to be lower and this is due to the amount of energy stored at that potential. 0.1v is not a huge thing. You can connect them...

Note that the charging settings should firstly be set om your Charger ;) so look into Them so they are callibrated against the bms. Preferable below by 0.1v or so.

It should be. But as Said throttle is for balancing and should only happen when it need to balance. I think you have wrong settings as Said :)

Please Read My post again. Both exist but its only full - throttle - offand IF its not set Up properly you get theoscilations.

Then you just need to install Portainer and have access so you can logon to it and edit the configuration afterwards. Then also install local Mosquitto. Then if you want grafana graphs you install influxdb and Grafana on top. Beware of that if you dont run this install on SSD or enterprise SSD...

I think i added wrong image since it was discharge but charge is same:

As i said it sends ON - throttle(lower) - OFF. The BMS is not to PID control the charger thats for the charger to do. The "throttle" level in the middle is to tell the inverter "Hey we have one cell that isnt balanced so total voltage is wrong and i cant keep up balance. Please can you reduce...

Are you running a pure HA install or installed HA on raspberry OS?

I will publish a video tomorrow regarding installing Watchmonudplistener on Home assistant if thats interesting. :) If so stay tuned for that. Though im not going into grafana on home assistant. Never used it there myself since raspberry pi have limited resources.
