I have been using the iPhone Geofency app for some time now as a replacement for the Homey Build-In Geofencing feature. For example because…
- it’s possible to adjust the geofencing radius between 50 and 550 meters
- it’s possible to monitor multiple locations
- there is no need for additional Homey apps like the OwnTracks app, because entering and leaving is triggered via WebHooks
…and a lot more features.
Until now, I used only the normal “coming” and “going” features. But the Geofency app can also detect if you enter the geofencing area on foot, by bike or by car. This could be used, for example, to automatically open the garage door only when you come home by car.
The problem now is that the WebHook doesn’t send just an Event and a Tag, but a lot more information. These are the WebHook parameters:
{"id": "{Location identifier)",
"name": "{Name of the location}",
"entry": "{»1« Entry, »O« Exit}",
"date": "{Time stamp (RFC 3339)}",
"latitude": "{Latitude}",
"longitude": "{Longitude}",
"address": "{Address string of the location)",
"radius": "{Monitoring radius)",
"category": "{Frequent, Monitored, iBeacon}"
"device": "{Device identifier}",
"beaconUUID": "{iBeacon UUID}",
"major": "{iBeacon Major No.}",
"minor": "{iBeacon Minor No.}",
"currentLatitude": "{Proximity Latitude}",
"currentLongitude": "{Proximity Longitude}",
"wifiSSID": "{WLAN SSID}",
"wifiBSSID": "{WLAN BSSID}",
"motion": "{Motion type}"}
In addition, the app developer of the iOS Geofency App also provides the following sample codes for download:

However, I have absolutely no idea what to do with it… 
After I had already tried a few things with the Build-In Webhook flow cards with no success, I found a tutorial where the Homey App Webhooks was used. So I installed the app and did again some tests.
After replacing the webhooks in the iOS Geofency app with the Webhook URL from the Homey Webhooks app and creating just a simple flow with a timeline notification card, I received the following infos:
{"latitude":"52.51608","longitude":"13.37993","device":"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX","entry":"1","radius":"100","id":"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX","address":"Unter den Linden 77\n10117 Berlin\nDeutschland","name":"Webhook-Test","category":"Monitored","date":"2024-11-17T12:07:35Z","motion":"automotive"}
(Personal information has been made unreadable or has been replaced)
So I created a simple AF that gives me, just for testing purposes, a timeline notification as to whether I came home on foot or by car, and it works!
But I would like to realize it without the Webhooks app and just use internal Flow cards. Is that even possible? If so, can someone show me how?
