Range issue with 433mhz.
After having some initial problems with adding nexa units I narowed the issue down to a range problem.
If I have the Nexa plugs (pbr-2300 and the supported Nexa EYCR-2300 plugg) within 3m of the zipato box it works just fine, I can add the pluggs, turn on and off. But if the pluggs are more than 4 m away from the box it does not work.
This is in clear line of sight, with walls between the pluggs and the zipato box the range is even less.
Much appreciated if you could help me understand what the issue is and how to rectify it.
