Select the command relay you want to use on the drop-down list, and then choose the device(s) and/or device group(s) you want to send the command to from the drop-down menu respectively. Key-in the command you want to send in the Command field, and then click Send Adhoc Command.
You should be able to see a notification saying that your ad-hoc command has been sent.
