When I saw that Flic HomeKit-compatible smart buttons were available, I had to take them for a spin.

Second-generation Flic smart home buttons now have HomeKit compatibility, along with multi-color LEDs to indicate the status of the device they control.
The original Flic buttons from Shortcut Labs could control a reasonably wide range of devices — including Ikea, Nanoleaf, Lifx, Lightify, Philips Hue, Sonos, Spotify, and WeMo — but HomeKit support now makes them suitable for a much wider range of smart home products
