Changing the spotify player in a rule file

I am trying to change the device spotify plays from in a rule file and can’t seem to make it work. (it works fine using the paper UI) … Any ideas what i am doing wrong

“spotify:player:Dave:deviceName” is the channel shown in the paper UI

My rule …

sendCommand("spotify:player:Dave:deviceName","Kitchen Bose");

Thanks in advance

Did you try sending the command to the item?

Thanks for your help, I now understand my mistake … I needed (as you actually suggested) to send it to the bridge item, not the bridge channel.
