APC UPS Daemon
apcupsd
The APC UPS Daemon integration is used to integrate with UPS devices from APC when the Network Information Server (apcupsd) is configured on the APC devices. Use case: When the Notify integration is set up in Home Assistant, you can send notifications. For example, when the UPS switches to battery power, or when the battery level drops low. You can also use it to track the UPS load.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |
|---|---|---|
binary_sensor | Sensor (motion, contact, leak, smoke…) | |
sensor | Sensor (humidity, temperature) |
What people report
APC UPS units work read-only via the apcupsd daemon. UPSes that report a blank serial number can't be added twice.

| APC UPS via apcupsd | Partly works | Read-only; no self-test control; blank serial blocks adding multiple unitsSaved copyHello, Thanks for your reply. Sorry I didn’t make it clear. They are totally connected to different devices. Different raspberry pi, different UPS and different apcupsd services for sure. However, both of them are configured by apcupsd on the Linux so I wondered if there will be some UUID set to the same for this. As I mentioned earlier, I tried to set UPS name in difference, but this didn’t get resolved. Excerpt saved from GitHub on 2026-10-23. | Issue #136219 · 2025-01 |

Limitations from the docs
- This integration does not allow you to control the UPS. For example, you cannot run a self-test. To run a self-test, use the apctest command provided by apcupsd.
In ReReHome
Whatever HomeKit Bridge shares reaches Apple Home as normal HomeKit accessories behind your Home Assistant bridge, so ReReHome shows and controls them like any other.
Bridges get their own settings page listing the accessories behind them.
