A have issues with disconnecting radio when 5 and more meters away, but I need more. Is it possible?
Is this a 1st or 2nd Gen controller and Brain? If 1st Gen, you can use the 2.4GHz radios instead of the Smart Radios - in my experience the range of the 2.4GHz radios is very good.
Also, if it’s gen 1 you could use an Ethernet cord.
