[solved]Set value of DummyDimmer by script

---

I have a DummyDimmer class to control the volume of an mpd stream.

{
  "class": "DummyDimmer",
  "id": "radio-volume",
  "name": "Radio Volume"
}

And the according rule is:
"if $radio-volume.dimlevel changes then execute \"/usr/bin/mpc volume $radio-volume.dimlevel\"

Now I would like to change the dimlevel by a script/rule or via the api. Only valid syntax I have found is
toggle radio-volume
which changes the dimlevel from 100% to 0% or vice versa.

So any idea of how to set the dimlevel to e.g. 75% ?

Many thanks in advance!

with the api you can use:
http://IP_OF_PIMATIC/api/device/radio-volume/changeDimlevelTo?dimlevel=75
and then your rule should change to volume.

But I don’t have a dimmer device, so it is untested!

@techbarney: He man,

thank you very much. Works like a charm!

Just for the records:
To change the dimlevel to a value (here 75%) by using curl (from command line or as script) you have to call:

curl \
-X GET \
--header "Content-Type:application/json" \
--data ' {"dimlevel": "75" }' \
--user "USERNAME:PASSWORD" \
http://YOUR_PIMATIC_URL/api/device/radio-volume/changeDimlevelTo

If you are working with the socket.io.js library the call is:

socket.emit('call', { id: 'radio-volume', action: 'callDeviceAction', params: { deviceId: 'radio-volume', actionName: 'changeDimlevelTo', dimlevel: '' + value } });

Cheers,
