Aspire 9542 and 9540 has this been solved

Hello am newbie and have read several different project questions and havent really seen a fix or maybe my hours of searching were not as productive as I thought. Have 1 9540 and two 9542 auxiliary switches and used the smart lightings automation still the switches seem intermittent , master always works and most of the time so does one of the auxiillary switches but the other one will usually go off and then come back on.
