I live in a very crowded area and after I hooked RFLINK to Domoticz I added my own 433 Eurodomest switches by manual learning using the remote control buttons.
After a few hours I see in devices of DMZ new units with the text Unknown that are not mine form other manufacturers like Elmes, Aster and EV1527.

About 25 units of which I think are from the nearby supermarket.
So RFLINK pics up more signals.
I googled the names and they all are linked to 433 products.
If I click one of these units can I control them on and off? No intention but just for my confirmation.
If I can, then I assume if someone else is running a same system like me in a nearby area he can control my units too?
Is my thinking correct?
