NUT UPS Monitor

NUT UPS Monitor is a companion app for Network UPS Tools (NUT), bringing your UPS information to your iPhone. It requires an existing NUT server reachable over your local network or VPN. Check power status, battery charge, load, runtime and available voltages at a glance. The app discovers the variables published by each UPS and shows only the metrics available for that device. FEATURES • Save multiple NUT server connections and select the UPS you want to view. • Compact dashboard that updates every 15 seconds while the app is active. • Battery, load, voltage, runtime and power charts with 1, 6, 12 and 24-hour ranges. • Local history of observed readings retained for 7 days. • Events for switching to battery, power restoration, low battery and significant input voltage drops. • Adjustable battery and voltage thresholds. • Optional local notifications for events detected while the app is active and connected. • Export recorded readings and events as CSV. • Explore Demo with sample data to try the app. • Light and dark appearances. YOUR DATA STAYS WITH YOU The app connects directly to the NUT server you configure. Passwords are stored in the iOS Keychain, and history stays on your device. Free to use, with no accounts, advertising or subscriptions. REQUIREMENTS AND SCOPE Requires an iPhone running iOS 18 or later and a configured NUT server. The UPS can connect to the server through USB or another method supported by NUT. Use a trusted network or your own VPN: NUT TCP connections in this version are unencrypted. Monitoring pauses when the app goes into the background or closes. Charts and events show readings observed while the app is active; an event that occurs entirely during a pause may not be recorded. Estimated power is marked with ≈ and is not a measured wattage reading. NUT UPS Monitor is an independent app that complements NUT.
