  • It’s probably not undersized. You might have a duct leak, insulation gap, air gaps, etc.

    You might have rebates in your area that pay for some of these things. One inexpensive thing you can do is run reflectrex across your roof rafters. While you’re up there air seal any gaps into the living space like can lights and hvac vents.

    You can also seal your windows with plastic.

    You can get a flir camera for your phone to see where the heat is coming in the most.














  • I don’t consider snmp to be a big issue, unless someone set up “public” with write access.

    The ups software running on the windows machine would be running as system and would be able to execute whatever it wanted. Usually it’s connecting to the ups through some method (IP, usb serial) to figure out what state it’s in, how much runtime is remaining, and if it needs to execute any stored scripts.

    How do you get a compromised UPS to upload scripts to the windows machine? That I’m not too sure about. I don’t think I’ve seen an ups management system that has that capability.
