Power cut off detector vs Sinlú Sensor

The primary feature is to detect grid power-off events. There are no reliable devices on the market that can cope with this. A mobile phone with the app installed should be plugged into a power outlet. If grid power goes down, the application sends a message via a Telegram bot. Currently implemented features: send telegram bot message when power is off or on (supports multiple chat IDs) error logging for failed Telegram notifications with 3 retry attempts per chat ID visual logs tab for monitoring power events and errors

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.

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.
