Frequently Asked Questions
Are the products hard-wired or wireless?
Your system is almost entirely wireless, communicating through encrypted wireless signals at home (Wi-Fi, Z-Wave, S-Line, among others) and to our secure servers over Wi-Fi and 4G LTE. No wires or holes in your home, no wires to cut or disable, and no landline necessary.
Certain products (Smart Touchscreen Panel, Wi-Fi Cameras) require a dedicated 110v Standard Outlet for power, but all data is transmitted wirelessly.
Can I move around any smart plugs I've purchased or am using?
You absolutely can. After moving it, we recommend you call our Customer Care team to ensure everything is still working as it should with the wireless mesh network.
How do I turn on and off my lights using the mobile app?
Turning on and off your lights is easy using the mobile app. Once smart lighting is installed in your home, navigate to the “Lights” section. Once there, you can tap the lightbulb next to the light you want to be turned on or off. A scroll bar will let you set your exact dimming level if the light has dimming capabilities.
Does the Smart Thermostat need batteries?
It all depends on the model of the smart thermostat that you have set up in your home. If your home has a C-wire (common wire) connected to the thermostat, batteries would only be used in the event of a power outage at home.
What kind of batteries do I need for all the smart products around my home?
Please visit the product page for the piece of equipment. The type and number of batteries required for each individual product will be shown in the Details section.
