Cheapest compatible dimmers?

Hi,
I am looking to replace my current dimmers and the prices seem to vary a lot.
Therefore I am asking which complete dimmer set (EU) is the most priceworthy?

Waiting for your advice!

This?

Thanks for your reply.
Yes, that’s a duwi but I think it needs another set to be complete.

Am I right if I need around 100 euro to get a working dimmer?

I use the dimmer plug modules from TKBhome. They are excellent and relatively cheap (up to $48 with free shipping), but are not wall mountable.

if you need a Wall mounted solution, you can control these dimmers with a TZ66D wall switch using group association, although this can double your overall cost.

TKB is planning to release the TZ66DD which is a wall mounted dimmer, you can try to contact them regarding ETA.

Actually I have exactly these sockets and switches. And have very good communication with the company.
The socket was working perfect but I’ve had some issues with the wall switch. I have the wall mounted switch already but they say it’s not dimmable and it does not register as a dimming module in vera.
