LifeQuality Lite: temperature and humidity always in view
The wireless climate meter from Ajax for rooms with strict requirements for temperature and humidity. Measures accurately, warns of deviations and automatically starts your climate equipment.
LifeQuality Lite continuously monitors temperature and humidity. If a value exceeds the set threshold, you receive a push notification and the device can start automation scenarios that, for example, switch on a humidifier, ventilation or HVAC system. This restores the desired climate without you having to attend to it. An Ajax Hub 2 or higher is required for use.
