What is battery-sentinel?

Battery Sentinel is a Python-based Home Assistant add-on that auto-discovers and monitors all your battery-powered devices—like Z-Wave sensors, Zigbee remotes, or even phones—right from the HA sidebar on the home assistant dashboard. It tracks levels with color-coded bars, sets per-device alert thresholds, and sends non-spammy notifications via UI persistent alerts, email, or mobile push, plus daily HTML reports and script triggers with context variables. No YAML editing needed; install via the github home assistant repo for home assistant os or supervised setups.

Why is it gaining traction?

Unlike basic HA automations, it offers a full management dashboard with sortable tables, bulk edits for battery types and thresholds, inline renaming synced to HA's entity registry, and smart deduplication of multi-sensor devices. Developers dig the zero-config discovery of battery device_class entities, live filters, and integration with any notify service or mobile_app service—no more scattered low-battery pings or forgotten CR2032 swaps in cultist base sentinel battery spots (sorry, Doom Eternal fans, this ain't taras nabad unlocks). With github actions for releases, it's plug-and-scan for home assistant matter hub or cloud users.

Who should use this?

Home Assistant tinkerers with 10+ battery devices, like Zigbee weather stations or door sensors that die silently after firmware updates. Z-Wave JS or Zigbee2MQTT users chasing unavailable alerts, or anyone on home assistant supervised wanting bulk tagging for smoke detectors without scripting. Skip if you're on github home assistant core/container—no Supervisor, no add-on.

Verdict

Solid for HA battery management if you run Supervisor; docs are thorough, UI responsive even on mobile. At 49 stars and 1.0% credibility score, it's early but battle-tested—star it on github home assistant if it saves your setup.
