I²C temperature sensor error

I have a problem with installing version 4.8.3 on a raspberry pi zero with a Seed WM1302 concentrator, which has no temperature sensor.

ChirpStack’s packet-forwarder/firmware probes the I²C temperature sensor at startup. On WM1302, this probe fails, and causes the concentrator to repeatedly reset.

There seems to be no where to disable the I²C temperature sensor.

What to do?
