APC UPS Daemon

apcupsd status information can be integrated into Home Assistant when the Network Information Server (NIS) is configured on the APC device.

There is currently support for the following device types within Home Assistant:

Home Assistant add-on installation

Install this unofficial add-on to use this integration with Home Assistant. Keep in mind that we can’t give you support for this add-on.

After installation, follow the instructions on the GitHub page to configure the plugin. Then continue to follow the integration configurations below.


To add the APC UPS Daemon integration to your Home Assistant instance, use this My button:

If you get ConnectionRefusedError: Connection refused errors in the Home Assistant logs, ensure the apcupsd configuration directives used by its Network Information Server is set to permit connections from all addresses NISIP, else non-local addresses will not connect.

Binary sensor

This integration provides a binary sensor for the following information from apcupsd:

  • UPS status


This integration provides sensors for the following information from apcupsd based on their availability. Each sensor is listed here along with their corresponding resource name obtained from apcaccess.

Some sensors are disabled by default, since they provide information that is only useful for advanced users. You can manually enable them in Settings -> Devices & Services -> Entities -> the sensor entity you want to enable -> Advanced settings -> Enabled.
