@ArnoDe it was definitely the deco unit making the noise. Turning them off and on stopped the noise momentarily. What fixed it was turning it off for over an hour then tuning it back on.

I have had X55's for a couple of years now. In the past few months my main unit has started making annoying electronic noise. I have 4 Units total all connected by CAT6. Only the "Main Deco" is...

Have two lots of x55 (different houses) and one set upgraded to v1.1.0 via the app and not the other? Is this a slow release? the functions of choosing how the satellites connect is great. only issue...
