QUESTION: What happens if you connect the green wire from the switch to the white neutral electrical wires. The white eventually finds a path to ground. Is it AC that intereferes with the radio. I remember some deviceses using power wires as antennae.<br />Back to my question. What happens if you tie the green wire to the white ones? by Gary A 11/30/2014
ANSWER: Beyond the safety implications and the violations of the electrical code, I'm honestly not sure. It may work, but it's still a really bad idea.<br /><br />If your electrical box isn't properly grounded and/or there's no ground wire in the cable leading to your switch, it's really better to resolve that than to short the safety ground to the neutral. One of the points of the safety ground is to provide a low-resistance path to ground in the unlikely event that neutral becomes electrified so that you'll trip a breaker instead of killing someone. by Owen D a
ANSWER: My experience is the GREEN wire must be connected directly to ground wire only for the switch will not operate. <br /><br />After the correct connection is achieved there is a one to two minute delay before the switch becomes operational.<br /><br />The switch has absolutely met my expectations. The MyQ App meets the advertised capabilities. I can turn the lights ON and OFF from anywhere and verify that I closed the garage door after leaving the house. These features are great. by Charles F a
ANSWER: You are correct that in a normal installation, the white wire and the grounds wire in the Romeo find their way back to the same bus bar in the fuse box. However by doing so, you are defeating a safety feature of your home wiring. I would not do what you are suggesting and I would look for a proper ground. by Thomas M a
ANSWER: That is a question for the manufacturer, other than that I would follow the directions it has an antenna. by Rick E a
ANSWER: If you connect the green and white together you possibly live the unit/switch therefore creating a serious shock when touched, and if the unit/switch internal parts fail the ground or green wire connected is the only thing that may save you or your home. The green wire connected to ground is probably the most important wire why chance it!!!! The switch already has a great antenna with great reception, it is the yellow wire which goes right into the wall. by Joe C a

ANSWER: AssureLink is a product of The Chamberlain Group, the world's largest manufacturer of garage door openers. Chamberlain makes Craftsman openers as well as Chamberlain and Liftmaster MyQ, its own branded internet-connected technology. The 823LM will work with either system as long as you have one of their Internet gateways installed. Chamberlain, Sears and Liftmaster are all made by Chamberlain and are all compadiable. Their apps are all the same, just a diff name on them. by Jim M a
ANSWER: All MyQ products are interoperable. No problems here. Liftmaster is just Chamberlain that is distributed by garage door installers.<br /><br />Just be mindful, that the switch cannot be wired for 3-way or 4-way switching. If your light or whatever the switch controls can be controlled by 2 or more switches, this will not work. If just one switch controls the light, you are good to go. by Eric E a
