I have been using the Lutron LZL-4B-WH-L01 Connected Bulb Remote with the Lutron PICO-WBX-ADAPT Pico Wallplate Bracket and really like them. They fit the standard size square switch plates so they can go in place of your existing light switch if you choose, or you can use them with your existing light switch. The problem with using hue products on a standard light switch is that when someone flips the switch off you can no longer turn the light on via the app or any other hue compatible switches. But with these you can remove the existing switch and just hardwire the lights on with a wire nut (hire an electrician to do it), put the bracket in place where the old switch was, pair the remote with your hub and any lights you want it to control (I also have mine controlling some table lamps), and you’re good to go. You can now turn your lights on and off at the switch, on your phone, with a Logitech Harmony remote, with a timer set thru the app, etc. The only downside I’ve seen to replacing the switch is that you have to use Philips hue bulbs for every light controlled by that switch (a normal bulb would now be on 100% of the time as you have hardwired the light on).
Pairing them is a little odd, you have to first pair the switch to the bridge and then to each individual bulb, if you pair the switch to the bulb before pairing it to the bridge then the bridge will no longer see the lights unless you re-add them by entering their serial numbers (I did this wrong a few times and it drove me nuts until I figured it out). There is a great youtube out there if you google “Philips hue with lutron connected switch”.
