What Zigbee switches are you using?

Made for UK wall switches.
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.
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.
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.
