More info

Secure SES303 is the latest addition to the stylish range of digital environmental sensors. The smart sensor from Secure provides reliable and continuous monitoring of temperature and humidity inside your home, and lets you improve the efficiency of your heating system. The Z-Wave sensor can be integrated easily into your home automation network and configured to be a part of intelligent scenes and scenarios.

It can be expanded to work with external wired NTC temperature sensor (SES 001) or pipe/tank temperature sensors (SES 002 / SES 003). The sensors supports configurable data reporting, and can be configured to transmit the information to an associated device in the Z-Wave network.

SES 303 comes with fixing compatible to British standard single gang wall box. As the sensor is battery powered, there's no need for external wiring and it can be installed within a matter of minutes.
