Help with Firebase IOT Offline Detection -- 2

Job ID: 31595368

Budget: $250 – $750 USD

I 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.
