Power cut off detector vs Sinlú

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

Your home. Your parents' home. Your business. Sinlú keeps an eye on the power at the places you care about, so you know when it goes out and when it's back, even when you're away. A SENSOR FOR EACH PLACE Create a sensor in the app and give it a home: a spare phone or a Raspberry Pi Pico 2 W, plugged in where you want to watch the power. It sends Sinlú pulses all day and all night. If they stop, you'll hear about it. • See every sensor's status at a glance, or on a widget • Get alerts when the power goes out and when it's back • Look back at past outages • Share a sensor with family so they can follow it too SEE WHAT'S HAPPENING AROUND YOU Follow the areas you care about, see where people are reporting outages on the map, and report an outage in one tap when it happens to you. Follow it live on your Lock Screen. Reports show what's happening in an area, not at a specific home. FREE, PLUS AND PRO Free includes one sensor. Plus supports five and Pro ten, and both add the Calendar, Insights, PDF exports and more map detail. Your sensor reports stay readable on every plan. You bring the phone or Pico. Memberships are optional and renew automatically unless you cancel through Apple. You'll see the price, billing period and any free trial before you buy. Available in English and Spanish. GOOD TO KNOW A sensor needs power and internet where it's installed, so stopped pulses can mean a power or an internet problem. Sinlú isn't part of any utility or emergency service, and its information can be late, incomplete or wrong.
