I'm always looking to simplify my rules and reactions and having finally grasped the Array function with a loop of perform.Action, I decided to re-write one of my rules. The kids like to play music on the Echo devices at a high volume, and I also have TTS loud during the night if a door/window are to open. In order to not have her yell at me later, I wrote a rule that resets the volume on each Echo device to a level of 2. However having 7 Echo's, there are many steps in my Reaction. Set the volume on device 1, wait a few seconds, set the volume on the device 2, wait, and so on.

Sample snippet of the set reaction: (This works BTW.)

To make it better, I created an array of the devices and want to run a perform.Action command. Less steps with the same results. Or so I thought. The end result is now a volume level of 0 or 1. I think the Echo gets confused. Either way, not a level of 2 like I was expecting. BTW volume 1 across the room is too low, in case you were wondering.

New set reaction:

${{ each device in Echo_devices: performAction( device, 'volume.set', { level:0.20 } ); 0 }}

The av_transport.stop works as expected. The issue is with the volume.set, {level:0.20}. Do I have something wrong in my command?
