Talking to Modbus modules from UPS companies

I’m curious if anyone here has used groov to communicate with the modbus modules from APC, Tripplite, etc that provides system information about their UPS devices. If so, do you have any recommendations or warnings?

Only wisdom I can give is that APC uses a non-standard RS-232 serial port pin out so you have to use their cable (or a custom made one) to connect to a 232 to 485 converter.

I know we have at least one customer using at least one Liebert UPS + groov (that system got to go to the Superbowl)!
