carconnectivity-plugin-campermode

A CarConnectivity plugin providing a mobile-friendly web UI for overnight car climatisation cycling - periodic heating/cooling with battery safety and timer scheduling (camper mode).

Features

• Periodic climatisation cycles (configurable duration and pause between cycles)
• Battery safety: auto-stop below configurable threshold
• Timer scheduling for automatic activation
• Mobile-first web UI at a dedicated port
• VW seat/zone heating disabled during cycles to minimise battery consumption (window heating, front/rear seat zones, steering wheel, mirror, rear window, windscreen)

Prerequisites

• CarConnectivity installed and configured with a connector (only tested with VW so far)
• Python 3.10 or later

Installation

pip install carconnectivity-plugin-campermode

Accessing the web UI

Once CarConnectivity is running, open your browser at:

http://<host>:<port>

where host and port match the values in your configuration (default: http://localhost:4001). If authentication is configured, you will be prompted to log in.

Configuration

Add to your carconnectivity.json (comments shown for documentation — remove them from the actual file as JSON does not support comments).

Note: carconnectivity.json contains credentials and should be readable only by the user running the service:

chmod 600 carconnectivity.json
