I think most are made in China and just relabeled under some EU brand.

Looking at IKEA smart plug with "Made in China" on it..

As other said IKEA and Shelly devices are solid choices.

Either you'll stick to one brand and live in their ecosystem or you'll have 10 apps for controlling various parts of your home. This typically leads to HomeAssistant and Zigbee works great there.

If you want less DIY solution, then Loxone (Austrian or German) or perhaps Jablotron (Czechia). These will cost a lot lot more tho.

I switched to IKEA home automation for the most components.

It is Zigbee and with the newest stuff Matter. Quite affordable and mostly well thought out

IKEA, Shelly, Hue. I doubt there’s much that’s actually manufactured locally unfortunately.

Homeassistant is virtually a necessity.

Aren't the devices from FRITZ! European? Please correct me if I'm wrong. :)

Most companies that I see that are local to Europe are German, and I know a handful from here in Sweden

Shelly is as far as I know from EU, but I don't know where they produce the devices, might want to look into that
