+The automation example below shows how to send a command via the harmony remote using the `send_command` service to send the 'Pause' command to the hub, which is already defined as an IR code for each device to be used via the Harmony app. It is checking for the activity name as exposed through the sensor in the harmony remote component using Jinga if statements to set the device_id, sending the correct Pause command for the given activity. This requires checking your activity list and device_id from the `harmony_REMOTENAME.conf` file created when you start the component. In this example, the harmony hub is named bedroom.
