A simple and open source solution to get an alarm when your horse foals.
The small device can be simply mounted on any horse holster.
Using a recharchable battery, WLAN and instant App notification for Android and iOS.
Device: 3D printed case, rechargable battery, WLAN, customizable
Server: Go (Gotify with Docker)
This device is sending an instant alarm if the horse lies down to foal.
I looked for a proper device that is affordable without GSM as transmission method. We have no cell phone network in our stable, but WLAN. I did not found any products using WLAN with simple App notification - so I build it myself.
The device is mounted on the chin strap of the horse's holster. A gyro sensor is tracking the devices position and triggers an alarm if the horse lies down. The push notification is sent to a server, where the registered Apps are notified.
