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.
i am in the same situation like you. There are some german telegram chats about smart home in caravans and some people have reverse engineered the bluetooth protocol or intercepted the cables. but there is no ready made solution…
I was able to communicate with the Fendt Caravan via Bluetooth using an ESP32 C3. I started developing an ESPHome component. I have completed the implementation of the Main Control Unit and Alde devices of the Caravan. I believe Hobby Caravan is also using the same interface. After finishing the Fendt implementation. I can start the Hobby Caravan. But I need your help for testing.
Hi there… i whould really wanna test this on hobby caravan and see how it will be. I´ve been testing few things with hobby caravan, just started to reverse engineer bluetooth
If you could send me what you got and the way you got it to work, i might be able to get it to work
Hi,i would also appreciate an integration for the Hobby Connect bluetooth connection to my caravan
Reverse engineering Bluetooth is way above my capabilities so any help would be greatly appreciate
