A MQTT connector for devices, sensors and programms mostly used in camper vans. With support for Home Assistant.
-
Run the install script:
curl -o- https://raw.githubusercontent.com/schroeder-robert/vantelligence_connector/develop/install.sh | sudo bash -
Choose on of the config files in the
connector/configfolder and rename it toconfig.yaml.Alternatively you can build your own config from the blocks from
Supported devices/sensors/programsif you use a custom setup. -
Restart & you're ready
After successfull start you will see some new topics in yout MQTT broker.
Your configuration will be published in this topic:
connector/config
All entities and their states will be published here:
connector/devices
You can add this config blocks to your config.yaml to activate MQTT publishing to your broker.
Every device has at least an id and a name which you can define. That way ist is possible to read two oder more sensors of the same type.

⚠ Important System Requirements
Disable GPIO interrupts (source)
If running a newer Raspbian release, you will need to add the following line to
/boot/config.txt and reboot:
dtoverlay=gpio-no-irq
Without this you may see crashes with newer kernels when trying to poll for pin changes.
Use GPIO pins of a Raspberry Pi as input, output or pwm as swi.
