In the pending repository (the place where the data models can be developed if you wish) there is an interesting working going on about sensoring related to water management.
In development is :
– A data model for the actuator
– A data model for the service which is related to the actuator
– Modifications of the device data model
– A data model for a gateway gathering the data of a group of sensors
They are in the very early stages (so not that much is being contributed).
