Practical automation example

Or have the bedroom automatically heated or cooled before bedtime based on the measured temperature.

Frequently Asked Questions (FAQ)

• Does this sensor work with Home Assistant, Homey and Fibaro?
  Yes, provided your Z-Wave controller supports the sensor.
• Is the ZSE44 a repeater?
  No, only non-battery powered Z-Wave devices can pass the signal.
• Can I change the reporting settings?
  Yes, you can adjust the threshold and interval via the advanced settings.
• Is outdoor mounting possible?
  Yes, as long as the sensor remains dry and out of direct sunlight, for example, under a canopy. A bracket is included with the 800-series sensor.
• What is the recommended operating temperature?
  The operating temperature is approximately 5–40 °C (40–90/104 °F), which is suitable for indoor and sheltered outdoor use.
  
• Up to what temperature can the sensor report?
  The sensor can detect and transmit temperatures up to approximately 49–57 °C (120–135 °F), but this is well outside the recommended operating range and is intended for short-term exposure.
  
• What is the difference between 'operating temperature' and 'reporting range'?
  Operating temperature: the safe range for long-term and reliable use of the device.
  Reporting range: The range within which the sensor can still measure and transmit values; this may temporarily exceed the operating temperature, but is not recommended for permanent installation.
