Network UPS Tools (NUT)
nut
The Network UPS Tools (NUT) integration allows you to monitor and manage an Uninterruptible Power Supply (UPS) for battery backup, a Power Distribution Unit (PDU), or other similar power device using a NUT server. It lets you view the status, receive notifications about important events, and execute commands as device actions for one or more such devices.
In Apple Home through HomeKit Bridge

button | Button (as a switch) |
What people report

| Tripp Lite UPS | Partly works Local | Works; device info fields had trailing whitespace, since fixedSaved copyDescription The NUT (Network UPS Tools) integration passes through device info values (manufacturer, model, firmware, etc.) from UPS firmware without trimming whitespace. This results in trailing spaces appearing in the device registry. ## Example A Tripp Lite UPS reports the following values via `upsc`: - manufacturer: `"Tripp Lite "` (trailing space) - model: `"Tripp Lite UPS "` (trailing space) These values are stored as-is in the Home Assistant device registry: [code] ## Expected behavior Device info string fields should be stripped of leading/trailing whitespace before being stored in … Excerpt saved from GitHub on 2026-10-23. | Issue #166186 · 2026-03 | |
| Riello iDialog IDG 600 | Not working Local | Battery and other readings wrong via riello_usb driverSaved copyThe problem Hi I bought an UPS for my Home Assistant setup. Model is Riello IDG (iDialog) 600 and is referenced as compatible with NUT using the "riello_usb" driver. I followed the documentation to setup the NUT add-on and integration and connect to the UPS via USB cable. All is working well, status and sensors are well updated and within reasonable time. The issue I have is that some sensors that I find important are showing incorrect values and I miss them to fine-tune my automated notifications. I cannot say if these values are wrong because they are incorrectly reported by the UPS itself … Excerpt saved from GitHub on 2026-10-23. | Issue #79703 · 2022-10 |
