# Battery Monitor

> Battery Monitor is a Marketplace integration for Home Assistant. It has 529 installs sharing analytics, works locally and was last updated October 20, 2026.

Battery Monitor is a custom integration that gathers every battery entity in Home Assistant into one overview. It finds battery entities automatically by device class, with an optional name-based check for sensors that report a percentage. Summary sensors report the monitored total, how many are low or at zero, the lowest battery, percentages, a traffic-light status and a list of devices below the threshold. Low and critical thresholds are adjustable, and filters can include or exclude entities by domain, selection or name pattern. Unavailable batteries keep their last known value, which can be limited to a set number of hours, and a notification can be created when a battery reads 0%. It works locally and is set up in the UI.

## Supports

- **Works locally**: Talks to your devices on your own network. No vendor cloud in between.
- **From the Marketplace**: Installed through the Marketplace, formerly HACS.
- **Actively maintained**: Its author released or pushed a change in the last six months.

## Setting it up

Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services.

### Battery Monitor

- **Low battery threshold (%)**
- **Critical battery threshold (%)**
- **Use heuristic (battery in name/entity\_id) in addition to device\_class**
- **Domains to scan (comma-separated, e.g. sensor, binary\_sensor)**
- **Include only these entities (multi-select)**
- **Exclude these entities (multi-select)**
- **Include only entity\_id matching (fnmatch, comma-separated)**
- **Exclude entity\_id matching (fnmatch, comma-separated)**
- **Ignore 0% when calculating the lowest battery**
- **Treat unavailable batteries as 0% (when no last known value exists)**
- **Keep last known value of unavailable batteries for (hours, 0 = until the entity is removed from Home Assistant)**
- **Notify when a 0% value appears**

### After setup

- **Low battery threshold (%)**
- **Critical battery threshold (%)**
- **Use heuristic (battery in name/entity\_id) in addition to device\_class**
- **Domains to scan (comma-separated, e.g. sensor, binary\_sensor)**
- **Include only these entities (multi-select)**
- **Exclude these entities (multi-select)**
- **Include only entity\_id matching (fnmatch, comma-separated)**
- **Exclude entity\_id matching (fnmatch, comma-separated)**
- **Ignore 0% when calculating the lowest battery**
- **Treat unavailable batteries as 0% (when no last known value exists)**
- **Keep last known value of unavailable batteries for (hours, 0 = until the entity is removed from Home Assistant)**
- **Notify when a 0% value appears**
