Hi Homey community!
I’m excited to share my first Homey app: Hail Protection Switzerland – an integration for the Swiss hail warning system hagelschutz-einfach-automatisch.ch, operated by the VKF (Vereinigung Kantonaler Feuerversicherungen) together with SRF Meteo.
The app polls the METEO REST API every 120 seconds (as required by the API spec) and triggers Homey Flows the moment a hail warning becomes active for your location – giving your smart home time to react before the hail hits.
Features
-
Automatic hail warning – trigger any Flow when currentStatechanges (e.g. raise all blinds instantly) -
All-clear detection – trigger a Flow when the warning is lifted -
API connection monitoring – alarm + Flow trigger if the API becomes unreachable -
Poll watchdog – triggers a Flow if no successful API call has occurred for more than 10 minutes -
Last poll timestamp – always visible on the device tile -
Configurable poll interval (minimum 120 s per API spec) -
Fully translated in German, English and French
Example Flows
Raise blinds on hail warning:
WHEN: Hail warning is active THEN: Start flow → Raise all blinds
Lower blinds when all-clear:
WHEN: Hail warning cleared THEN: Start flow → Lower all blinds
Alert if API is unreachable:
WHEN: API connection failed THEN: Send push notification
