Cheap dual channel wall switches that fit EU\RU standard in-wall mountbox

Hi! I’m sure it’s been asked a lot, but here I am anyway o.o

TL;DR - What options are out there for cheap-ish dual channel wall switches that fit EU\RU standard in-wall mount box? ZWave, ZigBee or WiFi, anything works. I already have ZWave usb stick, Hue Hub for ZigBee devices and Wifi… well, it’s wifi. I can’t fit Xiaomi Aquara switches, and I don’t want to bother with flashing Tasmota on Sonoff switches.

Thanks for your time and attention!


Some Details

Right now I only need to replace one failed Philio switch with something else, but I’m also planning for a new house. I’m hoping to find a prebuilt solution, not a plug that you place behind a regular switch, if possible.

I really loved Xiaomi Aquara switches, cheap and ZigBee, but they are too large to fit standard boxes and I don’t feel like I have time to make it larger. It’s in the concrete wall.

Sonoff has nice touch switches but I don’t really feel like I want to bother with flashing Tasmota on it. Also it’s WiFi, ideally I’d like to stick to ZWave or ZigBee.

ZWave’s downside is it’s frequency fragmentation, for some reason there are different frequencies in US, EU and RU regions, so that makes it even harder to find something =\

ZigBee seems to be more universal in this regard.
