These light switches are great. Simple and easy to set up and use. However, at times when I press the on or off button, there is no response. Not sure if what part of the system is glitchy...my ADLS1 internet, the switch or the app. They do work 9 times out of ten and still happy with my purchase.
These can be mounted anywhere you want, multiple different ways supplied. Or you can lift the switch out & use it like a remote. Like most things Philips it can be programed etc to do different things not just on /off.
