Help with Firebase IOT Offline Detection

Job ID: 31649067

Budget: $30 – $250 USD

need help implementing offline detection for my IOT device + app. The app changes values/settings in the firebase realtime database, then the IOT device checks and updates itself based on any changes. I need to be able to notify the app/smartphone when the IOT device is unexpectedly disconnected.

Right now it is a simple android app + hardware is based on ESP32, I can work with you on those areas, mostly looking for a firebase expert.

How would you go about sending notifications when the device gets disconnected? How would you go about implementing it in the firebase database? FYI, the app was created in FlutterFlow
