Square (EU) switches and dimmers

There are some. The most important question is do you have a neutral at the switch box. If you do, you have a lot more choices because the neutral is used to power the radio inside the switch. There are a few options if you don’t have a neutral, mostly micros from various different brands including Aeotec, Qubino, and others.

What country are you in? That does sometimes make a difference.

For example, if you have any trouble at the switchbox, the TKB line is quite popular and costs less than most of the micros:

There are some inexpensive Chinese Off brand switches that don’t have safety certifications, but I don’t recommend those personally. For fire safety reasons, I look for devices that have good certifications.
