Carl, thanks for the tip. I do have the tpPLC utility loaded. I see the base unit. The extender is visible and linked for the duration of the time the units remain paired. Once the 3-5 minute...

This is my second unit as I thought 1st was defective. Same issue with replacement. Pairs great to 2nd unit then disconnects after 3-5 minutes. In same room, same circuit and randomly disconnects...
