I’m not sure if this is actively being developed. All that’s here is the ability to view a few of my BMS parameters. Not even all of them. No BMS configuration options (yet?). It’s also odd that this program won’t connect with a Bluetooth BMS at extended distances where other BMS software seems to work fine.
