Do these need re-pairing when the switch batteries go?Quinetic every time for me, bulletproof never had any trouble with them and fitted hundreds of them over the years!
Can also link them to amazon alexa if you get WiFi receiversNo battery required they will do something like 20000 switches before they pack up! I've fitted hundreds over the years, only had to change 1 switch as it had died after 6 years of use! If they do go they can be re-paired with the unit with a push of a button and clicking the switch. Each receiver will do up to 10 switches afaik! And they do a grid module as Gavin said and key fob buttons and so much more!
