+## Capabilities
+
+* **Motion Sensor** - can detect motion
+* **Temperature Measurement** - defines device measures current temperature
+* **Relative Humidity Measurement** - allow reading the relative humidity from devices that support it
+* **Illuminance Measurement** - gives the illuminance reading from devices that support it
+* **Configuration** - _configure()_ command called when device is installed or device preferences updated
+* **Sensor** - detects sensor events
+* **Battery** - defines device uses a battery
+* **Health Check** - indicates ability to get device health notifications
+
+
+## Device Health
+
+Aeon Labs MultiSensor is polled by the hub.
+As of hubCore version 0.14.38 the hub sends up reports every 15 minutes regardless of whether the state changed.
+Device-Watch allows 2 check-in misses from device plus some lag time. So Check-in interval = (2*15 + 2)mins = 32 mins.
+Not to mention after going OFFLINE when the device is plugged back in, it might take a considerable amount of time for
+the device to appear as ONLINE again. This is because if this listening device does not respond to two poll requests in a row,
+it is not polled for 5 minutes by the hub. This can delay up the process of being marked ONLINE by quite some time.
+
+* __32min__ checkInterval
+
+## Battery Specification
+
+Four AAA batteries are required.
+
+## Troubleshooting
+
+If the device doesn't pair when trying from the SmartThings mobile app, it is possible that the device is out of range.
+Pairing needs to be tried again by placing the device closer to the hub.
+Instructions related to pairing, resetting and removing the device from SmartThings can be found in the following link:
