    Brilliant bit of kit
  

*by C***E on Reviewed in the United Kingdom on 3 August 2019*

Excellent kit! We needed an additional sensor to go in the babies room. This arrived promptly and was very easy to connect to the Velux Active app. We paired it to our daughters room and now that switch controls both her velux windows allowing us to shut both with just one click.Ideal being able to see the temperature of her room through out the night/day.Pricey for what it is but to be expected as the windows aren’t cheap let’s be honest.Highly recommend if like us you’ve got multiple rooms with multiple Velux Integra windows.

    Great once it is setup!
  

*by L***E on Reviewed in the United Kingdom on 21 October 2023*

I loved this system once it is actually setup and running. If gives you temperature, humidity and co2 ratings fof the area in which the sensor is located. It also allows you to control roller shutters, windows and blinds when local to the unit. It only allows you to control roller shutters and the window vent remotely. My only gripe with the system is that it is a nightmare to setup and don't even talk to me about adding another sensor at a later stage. I have spent hours on the setup process and a couple of hours on the phone to Velux to sort the system out. So, a great recommendation if you are technical and have staying power. Not such a great recommendation otherwise. The usual only supports 2.4wifi just add to the challenges.
