I have just sent an request to Athom to update the app to version 0.2.0.
There is a lot of changed.
Becouse there is still no update function for devices in Homey you need to remove all your devices (sensors) and then re-add them.
You insights will be lost so make a backup for it before you make the update.
This is becouse i have change in the back-end so we now have one device card for each node instead of one device card for each sensor.
If you got some problems with the update, tell me and i will look in to it.
Awesome work Erik!
