Re: Device discovery for control/sensor schemas

[Steve Cooper <scoop@xxxxxxxxxxxxxxxx>]

The way the HV connector handles this is to have a additional parameter
called name so it reports

{
DEVICE=1
TYPE=INPUT
CURRENT=HIGH
NAME=My switch
}

It allow for user to send device=1 or device=My Switch.  Not sure if
that the way we want to go but it's the way it currently works.

In terms of discovery you could use the proposed zoning method where by
you send a device=MASTER to Type=Temp for all temp type items or
type=all and it would report the current reading of all devices that it
is the master of.
