You can specify which apps you want to receive update notifications about, and if you want to receive new apps notifications. It’s still WIP so it might not work 100% correctly yet.
The script running on my VPS polls the Homey App Store every 15 minutes to get the latest & updated apps. If it’s a new app, it will send a notification to all users who subscribed for the new apps. If it’s an updated app, it will send a push notification to all users who subscribed to update notifications for that app.
If you have any feedback or encounter any issues, please let me know!
