Understand your home’s climate
Keep track of indoor comfort with the Aeotec aërQ 8 Temperature & Humidity Sensor (model family ZWA057). It measures temperature and relative humidity, calculates dew point and can report conditions associated with increased condensation and mould risk to a compatible Z-Wave controller.
What it can help you do
- Monitor room conditions: view temperature and humidity in your compatible smart home system.
- Spot moisture risks: use dew-point and mould-risk notifications to decide when a room needs ventilation.
- Create practical automations: trigger compatible ventilation, heating or cooling equipment based on sensor readings and hub rules.
- Cover larger spaces: Z-Wave Long Range is supported when paired with a compatible regional controller.
- Choose your power source: use a CR14250 battery or a suitable USB-C power supply.
