Terma Heating Element Accessory, White

Terma VOS open window sensor is an accessory part of the Terma SMART app, with fully integrated wifi functionality (note: this is not compatible with Amazon Alexa, Google Assistant and IFTTT). Once added to your network as a working device and fitted to your window, this accessory will track when the window has been openined and feed this information back to the main system. The small housing of the sensor is suspended on the mounting plate, which enables easy removal of the sensor from the window whenever necessary (it is also possible to mount the sensor directly on the window frame). We recommend attaching the sensor components to the frame with double-sided tape (without using screws). The set includes power batteries (2 x AAA).
