Hi.
I have BSMCEO4U and BSMCI14E .
BSMCEO4U  is on USB , I use USB isolator , but still noise (for example from my desctop lamp) reset communication - big trouble ..
BSMCI14E is on LAN , use UDP communication , port 1234 , 1235 , if click with mouse to Rest button then randomly switch On or Off
Output's .

What controller you use and you don't have this problem?

regards.
