So, Ive found an old NorthQ Z-wave sensor that is supposed to report energy usage.
Ive successfully paired it with the hub, using a generic z-wave device.
(Obviously) no sensor data being returned yet. EDIT: actually, using a predefined type of Metering Dimmer is giving some values…
Please can someone link me to a guide on writing a device-type!! ?
The following doc list some of the config variables and command classes.
