Bosch Smart Home Door/Window Contact II, Smart Sensor for Energy Efficient Heating, Compatible with Amazon Alexa and Google Assistant, Anthracite

Smart sensor: Reliably detects opened doors and windows, shows their status in the app and serves as a trigger for actions or scenarios in the smart home thanks to the integrated button.
Subtle design: The door/window sensor with an extra thin magnet (3 mm) fits discreetly into the overall picture of the living environment and can also be mounted on the window casement with multiple glazing
Save on heating costs: The window sensor detects open windows so that smart radiator thermostats are automatically throttled via the ‘sustainable ventilation’ service to save on energy costs.
Burglary protection: If the door/window contact is integrated into the Bosch Smart Home alarm system, it immediately triggers an alarm when doors and windows are opened without authorisation.
Maximum added value in the system: A Bosch Smart Home controller or Bosch Smart Home controller II is required to integrate into the Bosch Smart Home system.
Box contents: 1 x door/window senor, 1 x magnet, 1 x CR123A battery, tape, instruction manual (English language not guaranteed).
