Hello esteemed group 
.
I have a problem with the range of this device, when I put it in a box in the wall to control the roller shutter, the range drops/disappears terribly, even though the router is not far away. Can anyone suggest if it's possible to attach an antenna/rod to this device, point pin/place to increase reception? Because I'm not going to put an Access Point in every room ;/.
Thank you for your help.
Below are the pictures.
