Hello everyone, I wanted to share my recent experience installing GE smart switches in my home. As someone relatively new to smart home automation, this project was both exciting and challenging. I recently retired from the military, and now I have the time to explore this fascinating world. I’ve managed to set up several SmartThings devices and lighting automations, but installing these 3-way GE smart switches was a bit of a hurdle at first.I started by watching tutorials and reading through posts on this forum, which provided a wealth of information. The first set of switches I installed in my garage went smoothly, but when I moved on to the outdoor flood lights, I hit a snag. Determining which switch was the line switch and which was the load switch was confusing, especially since both seemed to be fed from the service panel. With power on and both switches off, I used a multimeter to check for voltage on the common terminal. To my surprise, both switches showed 120 volts, which didn’t make sense based on what I’d learned. I even shut off the power and did continuity checks, confirming both switches were working properly. After some research, I found a helpful post outlining nine different 3-way wiring scenarios. While none seemed to match my setup exactly, it gave me a better understanding of how to approach the problem. I realized my power source might be wired differently than the examples, and the neutrals weren’t tied together as I initially thought. I decided to tackle the downstairs location first, where I had a double gang box with a 3-way switch and a single pole switch for the porch light. The common terminal on the 3-way switch was jumpered and fed the single pole switch. I carefully rewired everything, ensuring the neutrals were correctly tied together and the travelers were properly connected. The upstairs master bedroom location was a bit simpler, with a single box and three runs entering through the top. I followed the same methodical approach, double-checking each connection before restoring power. After a lot of trial and error, I finally got both sets of switches working perfectly. It was a great feeling to see the flood lights respond to my voice commands through SmartThings. This experience taught me the importance of thorough research and patience when dealing with smart home installations. I’d like to thank everyone on this forum for their helpful posts and troubleshooting advice. It’s communities like this that make learning and implementing smart home technology so rewarding.
