Integration NEXA-lcmr100 in Homeassistent: Bäst gadget

Hello,
i have many switches from NEXA of this type https://www.dustin.se/product/5010762828/lcmr-1000-power-switch?ssel=false&gclid=CjwKCAjwuqiiBhBtEiwATgvixIKmYsm6oyVOE5KD3aVsuvcwdPrEWVt2cmZIB2O2Iv6kF9olih3qSBoCM7UQAvD_BwE.

I am looking for a way to controll them and interact with homeassistant.

I have Homeasistant on a Intel-NUC with unoccupied USB Ports.

Now i am looking for a futur-save device that will work with 433 MHZ signals “out of the box” and without any cloud service (with a possiblity to use external antennas).

Whats best to buy?

i found for example this device: https://shop.domo-supply.com/de/smarthome-zentrale/1010-rfxcom-rfxtrx433xl-usb-ha-controlle.html
Has somebody experience with it? I mean it seams to be a lot better than Tellstick Znet-Net lite - or?
