localTuya Integration Blind Motor not respondfing

I have two Tuya Blind Motors added to my HA localTuya Integration; one works one does not.
The working motor is identified as CW2GT V2 by Tuya, the non working one as RD Intelligent BlindMotor by Tuya.
Tuya cloud IoT developer site lists them as CW2GT V2 (working motor) and CW2GT (non working motor).
Both motors work under the HA Tuya Cloud integration but only the …V2 one works under the localTuya integration.
I can’t see any obvious reason for one not work. Can anyone help?
