Sonoff zbmini discovered as light in Phoscon App

I’ve been using deCONZ 2.13.04 on raspberry pi 3 with a raspbee2 firmware version 26720700. The switch pairs correctly and is usable via cluster info on/off command. At the webui, the switch is displayed as on/off light and is not usable:

Any ideas how to fix this?
