Asked 5 years ago by Millz2Paythebillz.

QuestionI have a switch in my garage that turns power on to an exterior outlet where my gutter heat tape is plugged into. I want to use this switch so I can turn the heat tape on when I am not there
Asked 5 years ago by Snowcountry.
- Answer Replace the switch with a Wemo light switch and you can turn it on with your phone from anywhere you have cell or internet service and you can set a schedule to turn it on or off based on your selected times. Or, use it like a normal light switch too.

QuestionI assume the switch can be turned on/off manually as well. But when you’re away from the switch and want to turn on remotely, does the switch have to be in the on position? Or does the remote signal (WiFi) connect to power when it calls for it?
Asked 5 years ago by Rene.
- Answer The switch can be in any state to control remotely. As long as your home WiFi connection is good & wherever you are has a good data connection, your WeMo app should show you the state of your switch presently & allow you to turn on, off or even schedule an action.

QuestionHow many bulbs can it control at once? I want to use this for a bathroom vanity light (5 bulbs but I use Low wattage LED bulbs)?
Asked 5 years ago by Cartermw.
- Answer You can use as many lights that is tied to the circuit. I have my switchs tied to led light and they work fine. As long as your vanity needs 120V to turn on you are fine.

QuestionWould it work if I just have a ground wire in the switch box?
Asked 3 years ago by Nelson.
- Answer To power up your switch you need the line (black), the load (red/black) for the light bulb and and the neutral (white). Ground either copper or (green) is to prevent you from getting shock. You can use a switch without the ground but you run the risk of getting shock or electrocuted. You add more ground wire to cover each light switch you add.

QuestionUpdated to a Eero 6 mesh. My existing Wemos, about 5 yrs old, will now not connect. Do I need new switches (6) to make this work? 2 of the switches are Wemo dimmers.
Asked 4 years ago by Switched.
- Answer First thing to check, does your Eero 6 support the 2.4ghz frequency? Do you have the same wifi password on Eero as you did on old router? My wemo's are new, but I just put in 17 and have Orbi Mesh. I had a few issues where I had to reset some of my wemo's to factory default. You can do that manually from switch or from the Wemo app and then go through setup again.
