Question about Philips Hue dimmer switch

Unfortunately no. The switch can only communicate with a Hue lamp directly or with the hub.

For quasi maximum flexibility in terms of home automation, I can recommend the WiFi Buttons from MyStrom.

E.g. myStrom WiFi Button Plus (wireless switch)

With this you can, for example, store a URL that is to be called up. In this way, you can control all kinds of things via IFTTT, for example.

Hope that helps.
