I have a similar approach (old clunky laptop with RS232 / 485 adapters) for monitoring batteries. i am not letting anyone onto that VLAN however. While I chafe at not having control of my BMS I can see why they lock them downAgreed. When they checked the battery via Teams I used a million year old laptop hooked to that battery via usb to serial cable, the laptop was wiped clean and connected to the internet via a separated Virtual network (DMZ style). Ubiquity router makes that fairly easy. Pain in the neck, but doable.
FWIW I don’t recall have to enter a BMS password, and I can still connect the laptop to the batteries and access the logs to see individual cell voltages over time. This is using their slightly clunky windows only software.
EG4s are also locked, but I haven’t asked for their PW yet
Do both have settings I would change, yep. Are any critical, nope
