ISTR the control.basic and sensor.basic schemas were developed about 12
months ago when the HV connector was being written.
The idea was to provide a standard means of controlling basic devices, such
as inputs, outputs, lights etc. without each device having it's own
specific schema.

An xpl-cmnd message using control.basic is used to control a device.
An xpl-trig message is used with sensor.basic when a device wishes to
report an event (e.g. button press etc.)
An xpl-stat message is used with sensor.basic for status reporting.

It's really up to the device developer to decide whether to use the
control/sensor schemas, or whether their device needs it's own schema.
For devices like the probe and FirM, I don't think control/sensor schemas
are appropriate, as these are specialist devices that I think are probably
best suited to their own device-specific schemas.

HTH,
