MeatPi WiCAN Pro (OBD2 reader)

Support tier: C (custom/manual)

What this is

MeatPi WiCAN Pro is an OBD2 + CAN adapter (ESP32-based) that can bring vehicle telemetry into Home Assistant: voltage, coolant temp, fault codes, trip metrics, and more (depending on vehicle support).

Why it’s useful in a van

  • Catch issues early (overheating, low voltage)
  • See driving/engine data alongside house systems
  • Build alerts before you end up stranded

Extra hardware required

  • An OBD2 reader (WiCAN Pro)
  • A compatible vehicle (OBD2)

Install / best next step

Two common HA approaches: - HACS integration (HTTP) (recommended by the WiCAN docs): add the device by hostname/IP and pull telemetry over HTTP. - MQTT: publish telemetry to your broker and optionally enable Home Assistant MQTT discovery.
