HW group: STE2 LITE

Remote monitoring of up to 4 sensor values with e-mail notification

The stand-alone STE2 LITE  unit has an RJ11 socket for external 1-Wire sensors for monitoring temperature, humidity, voltage, etc. The 1-Wire sensors, which can be connected in series, can record up to four sensor values.
Sensor data is displayed via the web interface of the STE2 LITE or on the screen of the  mobile phone / tablet. They can be retrieved from an online portal via an API. For the HW group products, the fee-based professional service SensDesk and the free HWg-Cloud with a limited service are available.
Via the external gateways SMS-GW / SMS-GW LTE with LAN interface or the SensDesk portal, STE2 LITE also alerts via SMS or voice call. The HWg- Cloud only supports e-mails.
Network connection via Ethernet and WLAN, power is supplied via a plug-in power supply.
