Getting Started with Wear OS and Android
1. Install (on both devices)
Ensure the app is installed on both your phone and your watch to get started. 
2. Check for ongoing notification
An ongoing notification should appear in your notification panel with the label 'Energy monitor is active'.
3. Remove device from the charger
Monitoring will begin once your device begins discharging. If the charge monitor is enabled, your phone will start receiving updates from your watch.
4. Wait for the first prediction
The periodic monitor will need to wait at least two intervals before it can make a prediction. With an interval of 20-30 minutes, this should take less than one hour.
Upgrading from Version 3: Version 4 is not compatible with previous versions of the apps. Make sure that SW Energy Monitor is up to date on both devices.
