+# Zen Thermostat
+
+Cloud Execution
+
+Works with: 
+
+* [Zen Thermostat](https://www.smartthings.com/works-with-smartthings/zen/zen-thermostat)
+
+## Table of contents
+
+* [Capabilities](#capabilities)
+* [Health](#device-health)
+
+## Capabilities
+
+* **Actuator** - represents that a Device has commands
+* **Thermostat** - allows for the control of a thermostat device
+* **Temperature Measurement** - get the temperature from a Device that reports current temperature
+* **Configuration** - _configure()_ command called when device is installed or device preferences updated
+* **Refresh** - _refresh()_ command for status updates
+* **Sensor** - it represents that a Device has attributes
+* **Health Check** - indicates ability to get device health notifications
+
+## Device Health
+
+Zen Thermostat with reporting interval of 5 mins.
+SmartThings platform will ping the device after `checkInterval` seconds of inactivity in last attempt to reach the device before marking it `OFFLINE` 
+
+* __12min__ checkInterval
+
+
+## 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.
+Other troubleshooting tips are listed as follows:
