Hello, I was happily monitoring my Seplos BMS in Home Assistant using esphome https://github.com/syssi/esphome-seplos-bms
It stopped working a few days ago showing all entities as unavailable; I spent days trying to fix it on the Home Assistant side with no success.
Today I tried using Battery Monitor to connect to the BMS (via the USB to RJ45 adaptor that came with it) and it also doesn't work; I tried a different RJ45 cable, tried both ports on the bms and it still doesn't connect (time out). I tried both 9600 and 19200 baud, no luck. It had always worked before.
I can still connect via bluetooth and the BMS obviously work, it's just the RS485 communications that seems kaput!
What could have happened? It stopped working on Monday; two days before I had added an MPPT to the system, but I can't see how it's related, apart from me disconnecting the battery a couple of times.
