Present child sensor capabilities

[pj-r]

There is now new switch type(SELECTOR) presented in Domoticz. With that its now possible to handle with V_HVAC enum switches.

Functionality for presenting sensors capabilities would help the contoller software to build automatically hvac switches for example.

For example:

• gw.presentcaps(childId, listOfValues) (user could define names for these in the controller)
• or even better: gw.presentcaps(childId, listOfKeys) (in this case values would be from 0 to count of list but names are provided automatically)
• or the best: gw.presentcaps(childId, listOfValues, listOfKeys). The contoller could buid up the switch from this info.
  One design question: Would this be called after or would it be alternative for gw.present(...)?

Keys would be used in UI of contoller and values(list of 8 bit int?) are what is transferred in messages.

For example my air source heat pump has only V_HVAC_MODE modes "Off", "HeatOn", "CoolOn". Values for these could be 0, 1 and 2.

Another thread from Domoticz forums
There is also example how this functionality could be used.

Another idea: present these values in loop:
presentcap(uint8_t childSensorId, uint8_t sensorType, char *valueName, uint8_t value)
Would it be easier to implement in library side?

I think we also have to have this sensorType defined in call since there can be multiple sensors/actuator within the same child: V_HVAC_FLOW_STATE, V_HVAC_FLOW_MODE, V_HVAC_FLOW_SPEED..
