The MA 10200 is an additional sensor for the Mobile Alerts system. It allows you to monitor temperature and humidity from your smartphone. In conjunction with the gateway and the "Mobile Alerts" app, you have the option to set individual alarm thresholds. If these thresholds are exceeded or not reached, you will receive an immediate alert via push notification on your smartphone. With the existing gateway and the installed "Mobile Alerts" app, temperature and humidity data is transmitted directly to your smartphone, allowing you to check the temperature and humidity of, for example, your terrarium at any time. Within the app, you can set alarm thresholds, and if these are exceeded or not reached, an alert will be sent to your phone. If the temperature or humidity rises or falls too drastically, you will be notified immediately, helping you to prevent significant damage. Additionally, the MA 10200 transmitter is compatible with Amazon's Alexa, so you can easily check the temperature and humidity levels at any time through an Echo device.
