When adding a Plugwise device to the app, a security key is created so that the app on your phone can access it outside the home. Sometimes things can go wrong. Then reset the Plugwise Home app:
- Make sure you are connected to the same (home) network as the Plugwise device (Anna, Adam, Smile P1 etc.)
- Open the Plugwise Home app
- Open the menu and choose 'Gateways'
- Swipe the line with the ID of your Plugwise product to the left
- Press the garbage can icon / delete
- Close the app
- Restart the app
- Add the ID of your Plugwise product again (If you have multiple Plugwise products in the app, select 'Gateways' in the menu and press the '+')
