Philips HueSmart Wall Switch Module Twin Pack. Works with Alexa, Google Assistant and Apple Homekit, Black

Ultimately they are really expensive for what they are but do allow you to use your light switch as you did before you installed smart bulbs. Really helpful for when you have visitors so you don't have to spend ages explaining to them how the lights work.To connect it up you essentially remove the switch from the lighting circuit so the lights are always powered. The switch is then connected up to this box which is just a battery powered Zigbee switch so sends a notification when someone flicks the switch.I use them in Home Assistant to trigger an automation to toggle Ikea bulbs in the appropriate room but I am guessing this is simpler if you are bought into the Hue ecosystem.

For anyone confused this product is a solution to the problem of not being able to use your normal light switches after installing smart bulbs. It installs behind the light switch and requires a basic knowledge of home electrics to be able to install.It comes with a connector block that takes the normal switch out of the circuit, leaving the lights permanently on, and the device itself which then connects to the switch. Once installed you connect it wirelessly to the hue hub and then you can use your switch again, just like the olden days.Typical Hue astronomical pricing but does the job well.

They're incredibly expensive for what they are, and they absolutely lock you in to the Hue ecosystem. But if you're already in that world, they do make a useful addition by allowing you to keep traditional light switches as another control for your Hue lights.

Have bought 9 of these modules in total. One failed and Phillips tech support replaced itThey are small but found that they could be a squeeze fitting them into the light switch wall box

You need to be confident at wiring a light switch or get an electrician. They are expensive but if you have hue lights and hub and normal wall switch, they are helpful. Each module can support 2 separate lights (as in a 2-gang switch), so I have one module controlling my outside door light and entrance hall light, as they use a 2 gang switch.

Really simple solution to bring smart to old British light switches.

If you have a hue light, install one of these behind the switch that controls it. This plugs in to the switch and disconnects the lighting ring from it. The light will be permanently on, and, then you can control it with your hue app or by using the switch. The switch module receives the toggle from the switch and then sends the command wirelessly to your dedicated light.This doesn't help you if you don't have a hue light, it won't convert a non-hue light to a smart light.

A good little device that removes the problem of people switching off a light and removing the ability to remove control a hue bulb. Set up was not straight forward as all of the guidance and videos are based around US or EU set ups. Essentially you need to use the Wymo connector supplied in the box to complete the switched circuit so that it becomes permanently live. The small wires connections supplied in the box then connect to either end of the switch. The hue module has no connection to the houses power supply and works solely off of a battery. The switch is then mounted back on the wall and used as normal.
