The GE Cync Smart Light Dimmer Switch adds smart bulb functionality to traditional bulbs and keeps LED smart light bulbs smart.

Q: Does this smart dimmer switch require a neutral wire for installation?
A: No, this smart dimmer switch does not require a neutral wire for installation and is compatible with homes built prior to the 1980s.
Q: Can I use this dimmer switch with other smart home systems like Alexa or Google Home?
A: Yes, this dimmer switch is compatible with both Alexa and Google Home devices without needing a separate hub.
A: PLEASE DO NOT DO THIS. The two ideas I could have of what you did are: A. You connected your neutral wire to ground and thus will be feeding current directly to ground, energizing the ground in your whole house which can short out other electronics at best, and cause multiple fires at worst. B. You do not have a ground or didn't realize that the copper wire in the box you installed this is what you'd connect the 'green' wire to. This means that any short the light socket has will just create a build-up in current and heat until something melts and/or causes a fire. While many old houses do not have ground wires, having a neutral wire but no ground is uncommon when I've done home electrical work. Please open it back up (after turning off power at the breaker) and check and see if you just missed the ground connection. If not, please talk to a licensed electrician about the wiring situation in your house as you may have a catastrophe on your hands in the near future. As someone who has installed these in multiple houses, they are fantastic and can drop in to any switch receptacle, but please get one that matches the wiring in your house.
