Generally this driver should work for all the APC Modbus UPS devices. Some devices might expose more than is currently supported, like multiple phases. A general rule of thumb is that APC devices (or firmware versions) released after 2010 are more likely to support Modbus than the USB HID standard.

Tested with the following hardware:

SMT1500 (Smart-UPS 1500, Firmware 9.6)

SMX750 (Smart-UPS X 750, Firmware 10.1)

SMX1500 (Smart-UPS X 1500, Firmware 15.0)

SMX2200 (Smart-UPS X 2200, Firmware 15.0)

Note that you will have to enable Modbus communication. In the front panel of the UPS, go to Advanced Menu mode, under Configuration and enable Modbus.
