The MA 10450 is a thermometer with connectivity to the Mobile Alerts home monitoring system. In combination with a gateway, this device allows you to permanently monitor your local indoor and outdoor temperature from your smartphone and to be informed immediately via push notification as soon as one of the limit values entered by you has been exceeded or fallen below. The MA 10450 can also be used without a connection to the Mobile Alerts System, but in this case the data transmission and alarm functions are not available.
