For CyberPower, a SNMP card might be your best bet. I don't have specific experience with the RMCARD205 that they recommend on their website, but most vendors seem to be able to get SNMP right. If nothing else, SNMP card firmware is usually upgradeable.

If you are mainly concerned about shutdowns when the UPS signals a low battery alert, then there is a good chance that the PR3000LCD* models are all supported equally well by the usbhid-ups driver. However, you may want to check the issue list if you are planning to depend on another threshold for shutdown: https://github.com/networkupstools/nut/issues?q=is%3Aissue+is%3Aopen+label%3A%22CyberPower+%28CPS%29%22

Also, you mentioned serial monitoring. I am not as familiar with serial CyberPower models, but take note of the support description here:


Most of the serial-connected CPS models have lower compatibility ratings due to this lack of public information:
