Keep an eye on the power at home with a spare phone. Sinlú Sensor turns a compatible phone into a dedicated power-monitoring sensor for your Sinlú account. Before you start Setup requires a Sinlú account and the main Sinlú app on another compatible phone. This phone does not sign into your account, and monitoring starts only after pairing and the safety acknowledgment. In Sinlú on your main phone, choose a sensor, scan or enter the code shown here, and approve pairing. Once paired, this phone sends sensor updates directly to Sinlú. The main app does not need to stay open. View remote status, alerts and history in the main Sinlú app. A focused job for a spare phone • Check this phone's external power and internet connection. • See its system thermal state, when available. • Follow the current session and the updates Sinlú has accepted. • Stop and restart monitoring. • Disconnect this phone while keeping the sensor and its history in your Sinlú account. Designed to stay at your place Leave the phone connected to the power source you want to monitor, with Sinlú Sensor open in the foreground and internet available. The app dims its monitoring screen during use. Normal sensor updates pause when external power, internet or required thermal information is unavailable, or when the phone becomes too hot. What the phone observes If the power source runs on a generator, inverter, backup battery or UPS, the phone may still receive power during a utility outage. Sinlú Sensor observes power supplied to this phone. It does not measure voltage or household energy use, and loss of contact alone does not confirm an outage. Compatibility and care Requires iOS 15.1 or later. Your main phone must support the main Sinlú app. Use only a phone and battery in good condition, a suitable charger, and a ventilated location. Follow the in-app safety instructions. Your Sinlú account A free Sinlú account supports one owned sensor. Additional capacity and some history tools depend on your Sinlú plan. Manage your account and sensors in the main Sinlú app.
