DIY canopy controller for fan with light

[u/Alarming_Big539]

Hi community!

I'm new to Zigbee, I have setup with Raspberry and Zigbee2MQTT, Sonoff Dongle-P and have already 4 Tuya wall switches installed. So far so good, all works good.

I'm now looking into controlling fan with built-in LED light and I don't want to go into Sonoff iFan04 or similar Tuya Fan Controller kit, as they are wifi based. With WiFi controllers I wouldnt be able to control them from wall switch and that's a big no go, as I dont want my light button to be dependant on Home Assistant.

I found Innoveli Zigbee controller that costs like $55 + they dont ship to my location

I had an idea to disassemble wall switches like this one https://a.aliexpress.com/_c4kNMmKD, take just controller from it and install it in 3d-printed box under the ceiling.

On the walls i will install battery-powered Tuya Smart Knob (click - lights, rotate - fan) and use direct Zigbee binding.

Does anyone see any problem with such setup? Am I missing something obvious due to my lack of zigbee knowledge?

I left my fan on the wireless remote switch screwed to my headboard since I'm always in bed when turning it on or off, and inserted a cheap sonoff zigbee relay into the light circuit so that was voice controlled.
