This custom driver connects your Aqara Climate Sensor W100 (Amazon link) directly to your Hubitat Elevation hub via Zigbee protocol. No additional hubs, bridges, or cloud dependencies required - just pure local control.
The driver can be installed manually from GitHub or using the community Hubitat Package Manager app. (TODO)

• powerSource: Power source type ['battery']
Advanced Configuration Attributes
These additional attributes provide specialized functionality and can be configured through the device preferences:
External Sensor Support:
• externalTemperature: External temperature sensor reading (when in external mode)
• externalHumidity: External humidity sensor reading (when in external mode)
Battery and Power Management:
• Battery monitoring attributes are currently work-in-progress (W.I.P.)

Device Health and Diagnostics:
• healthStatus: Real-time device connectivity status
• rtt: Network latency measurement for troubleshooting
• Status: Overall device operational status
Note: All temperature and humidity configuration attributes (thresholds, reporting modes, periods) are now exposed as main attributes and can be directly monitored and configured through the device interface.
Commands
Device Management:
• configure() - Configure device settings and initialize Zigbee attributes
• refresh() - Refresh all device attributes and current readings
• ping() - Test network connectivity and measure round-trip time
Button Commands:
• push() - Momentary push (simulates center button press)
• push(buttonNumber) - Simulate a button push event (button number 1-3)
• hold(buttonNumber) - Simulate a button hold event (button number 1-3)
• doubleTap(buttonNumber) - Simulate a button double-tap event (button number 1-3)
• release(buttonNumber) - Simulate a button release event (button number 1-3)

Advanced Features
Zigbee Attribute Control:
The driver provides direct access to all Aqara proprietary cluster (0xFCC0) attributes, allowing fine-grained control over device behavior including reporting modes, thresholds, and sampling rates.
Button Capabilities:
Full support for all three physical buttons with push, hold, double-tap, and release actions using the integrated buttonLib library. The driver provides comprehensive button capabilities including PushableButton, HoldableButton, DoubleTapableButton, ReleasableButton, and Momentary capabilities. Perfect for scene control and automation triggers with both physical button presses and programmatic button simulation.
External Sensor Support: (NOT working yet!)
The W100 can work with external temperature and humidity sensors, with the driver automatically detecting and reporting readings from both internal and external sources.
Health Monitoring:
Comprehensive device health tracking including power outage detection, parent network tracking, uptime monitoring, and battery health reporting.
Local Control:
All functionality operates locally without cloud dependencies. The device communicates directly with your Hubitat hub via Zigbee protocol.
