The Hobby group is one of the largest caravan companies in europe with a marketshare of 36% based on their brands Hobby and Fendt.
Hobby caravans can be controlled via Hobby Connect App since 2008. The app connects via bluetooth to the cravan to control temperature, lights, water level and stuff.
Hobby Connect+ (plus) was an addon for that, based on a Raspberry Pi 3(+?) and connected via mobile (2G?) you were able to control all that online from anywhere. Hobby Connect+ is discontinued end of 2025.
As I have a home assistant and ESP32 based bluetooth proxy in our caravan, I would like to ask if someone has the skill and fun to create a home assistant integration for Hobby caravans based on the local bluetooth connection. Reverse engineering the Hobby Connect app from AppStore/Playstore would be a great start to get an idea of what is going on.
I am no programmer, so could only assist with delivering data from our caravan. Don’t know if tools like Bluestack or something help to capture what is going on over bluetooth between the app and the caravan or something.
Hope someone finds this integration interesting and is willing to help.
