What people report

Works with UPS units via NUT; available values depend on what each UPS reports, and newer APC units report little.

Device	Status	What they said	Source
APC SMT2200 UPS	Partly works	Works but reports no consumption; newer APC UPS expose few variables Saved copy Here's the dump of `ups info`: It doen't look like your UPS reports consumption, nor anything that can be used to compute this. My UPS reports `ups.realpower.nominal` (nominal power in W) and `ups.load` (percentage of nominal power provided), which Homebridge UPS uses to compute consumption. I've also seen UPSs that report `output.current` (in A) and `output.voltage` (in V), which Homebridge UPS can use alternatively. [9/7/2024, 5:16:01 PM] [Mech Room Rack UPS] Mech Room Rack UPS Battery: Voltage: set to 30V [max] Hm, you have a (nominal) 48V battery, which actually runs at 53.1V.

Eaton 3S 850 UPS	Partly works	Voltage and consumption showed null; fixed parsing in beta, battery voltage stays 0 Saved copy Eaton 3s 850: set Voltage to nullV Homebridge UPS reads the mains voltage from `input.voltage`, which your UPS doesn't report. I suppose I could use `output.voltage` instead, or simply not expose _Voltage_. Eaton 3S 850 Battery: set Voltage from nullV to nullV Homebridge UPS reads the battery voltage from `battery.voltage`, which your UPS doesn't report. I'm afraid the only solution here, is not to expose the battery _Voltage_. set Current Consumption to nullW Homebridge UPS computes the consumption from `ups.load` (which indicates the load as percentage) and `ups.realpower.nominal`, which … Excerpt saved from GitHub on 2026-10-22.
