not GP, but I use Xiaomi 2-gang switches, IKEA 5 button remotes, the old IKEA dimmers, and their on/off remote. At the moment I'm eyeing LIDLs remotes as well... In Denmark

Everything is controlled via Homeassistant+Deconz and a Phoscon Zigbee Dongle.

It's even possible to hack the IKEA switches into the danish wall switches.

Here friends of hue Gira and Ikea 5 button remotes mounted on a blindplate.

Still wondering what @t0mas88 is using...

The upcoming Lidl remote is very interesting indeed, because it has 4 buttons which could be wired to a regular 2 button up/down push switch (e.g. Gira 014700) as cheaper friends of hue alternative.

The Gira here as well, and left physical switches behind them. So in an emergency I can pull them off the wall push the switch that's behind to turn off power.

Also 3d printed a holder for a few places that slots into a Gira frame and holds the Philips Hue Tap button. Allows more control of scenes etc, but the color isn't exactly the same.
