+
+<p>Sending a heartbeat from the MySensors device to Home Assistant activates the SmartSleep functionality in Home Assistant. This means that messages are buffered and only sent to the device upon receiving a heartbeat from the device. State changes are stored so that only the last requested state change is sent to the device. Other types of messages are queued in a FIFO queue. SmartSleep is useful for battery powered actuators that are waiting for commands.  See the MySensors library API for information on how to send heartbeats and sleep device.</p>
