OK so, I need to see what is going on in the morning, but I seem to have answered my own question : physicalgraph.device.HubAction(commandpayload)
Seeing that .format() returns a string value of the command sent, I was able to test this method using :
log.debug zwave.configurationV1.configurationGet(parameterNumber: 10).format()
which returned 70050A
I then ran HubAction(“70050A”) and received the following :
Parsed ConfigurationReport(configurationValue: [2], parameterNumber: 10, reserved11: 0, size: 1)
debug Parsing 'zw device: 26, command: 7006, payload: 0A 01 02 '
debug 70050A
Now running new physicalgraph.device.HubAction(“91010F2601016363”), I heard the motors whirring, but as it was late, I cancelled this. I will investigate further in the morning.
