I use a LaCross wireless set. I have one remote in my greenhouse and one at the rear of my property under a tree. It was a bit tricky to set up but once up, it performs well. The rear one is about 150 ft from the main unit. Mine is the older 430 Mhz unit. No troubles. Slightly less than a year battery life and I use premium rechargeables.

I'm looking for one that reliably transmits 100 ft or more, despite what descriptions might say. The first one I purchased said it would transmit 100 ft, and after checking, it reaches no more than 45 ft. Kathleen
