Pump status missing for unmixed circuit of IPM1 (Junkers)

Bug description Since V2.1 the pump status for circuit 1 of my Junkers IPM1 is missing (Device ID 0x20) in MQTT. This circuit is unmixed so the pump status was the only parameter that was being reported compared to the mixed circuit. It was present in V2.0.

Expected behavior Unmixed circuit 1 of IPM1 reporting the pump status.

Thanks for looking at this.

EDIT: It is also missing when I look at the console:

Mixer: Junkers IPM (DeviceID:0x20 ProductID:102, Version:20.08)
Mixer: Junkers IPM (DeviceID:0x21 ProductID:102, Version:20.08)
