Troubleshooting

Sensors show "Unavailable"
The integration could not reach motorist.co.th. Check your internet connection and HA logs (Settings → System → Logs).

A specific station sensor is always unavailable
That station does not carry that fuel grade (shown as "–" on the website). This is expected.

Prices seem outdated
Reduce the update interval in the integration options. Fuel prices in Thailand typically change once per week (usually Thursday evening).

Downloading diagnostics
Go to Settings → Devices & Services → Thailand Petrol Prices → three-dot menu → Download diagnostics and attach the file to any bug report.
