UK dimmer wall smart switch options

IM_WITH_STUPID_

Has anyone found a nice example of a Z-Wave, Zigbee or WiFi smart switch that will fit a standard UK wall box that can be used in HA?

​

I've got a couple of UK1 Sonoff Wall switches (i think that's the name of them) which once flashed are working as expected in HA without using EWeLink but i want something that can be dimmed.

​

I found these;

Which look the same, but i'm unsure if they use the ESP chip, but i'm considering buying one for testing. Before i do, i just wanted to know what other options might exist.

Thought i would provide an update. So i bought a couple of these tuya dimmer EU / UK style wall switches. They are ok, i'm not a massive fan of the glass panel or capacitive touch buttons, ideally some sort of physical slider would be idea for quick response would be much better, but limited availability in the EU / UK at the moment so they will do for now. You do need a neutral wire, but that's been ok for my installs at the moment but not ideal for some especially if you're in an older UK house where internal walls are solid brick.

​

Here's some photos of the module https://imgur.com/a/bV7r51k and you can buy it on either Amazon or Ebay and i'm sure other Chinese sites. I bought off ebay for £12 each direct from China, so factor in a bit of a wait. Packaging is simple brown cardboard no frills.

Integrates into HA just as any other switch and works well. Dimming isn't that smooth, so perhaps the PWM frequency is pretty low, but it's ok for the price. Flashing isn't as easy as SonOffs with pinouts but take your time and it's perfectly do-able.
