Hello...I'm new to the forum and need some direction from you experienced x10 users.
I have one X10 single pole wall transmitter mounted inside home and a x10 XPS3 receiver switch located in a water-tight box on side of my pool/spa control cabinet. Unit was installed new by electrician when home and pool was built in 2005. I could turn pool light on from switch at control cabinet or using the transmitter switch inside home. This worked as designed for about 4 yrs then inside transmitter would neither turn it on or off...receiver/switch at control cabinet outside will turn the light on or off. We've just been using the receiver as a switch since but would like to troubleshoot it and repair or replace as needed...getting tired of walking outside of screened enclosure at night to turn light on and off...wife likes to turn it on when entertaining. I pulled covers off and rocker switches to verify both were on same settings and they were. Should I assume it is bad and replace entire setup or could it only be one of the components that is bad?
