Add a link between command (params) & states?

Add a link between params & states?
A state could be used to keep track of setted parameters/values.

E.g. Temperature.
You set the tempretature via Command parameter in the range of 16-32°C.
The command is send to the device, and this "should" temperature is then setted as state.

Then there needs a link between the command "set temperature" & the state temperature.

A quick guess how it could be done: command & state alias.
If they are both the same, the (can) are linked.
Either automatically or with labels:

oh.link[0].state=POWER
oh.link[0].cmd=POWER

-- or --

oh.links[].enabled=POWER

But what then?
When commands & states are linked, what now?
