FAQs

General

The Lexi Hub is the heart of the Lexi Ecosystem. The Hub is what controls all the devices you configure in the Mobile App and it even has the ability to control third party devices like the Philips Hue or LiFX. Uniquely, the Lexi Hub is portable so you can take it, and most of the ART Lights, with you! Lexi does offer a No Hub option in which you can run the lights from the Mobile App with reduced functionality. In No Hub mode you cannot use the Art functions, marketplace, social sharing, reporting & analytics or sensors. You can begin in No Hub mode and then later upgrade to a Lexi Hub.

Smart home products use radios to send and receive information, which is what enables them to connect wirelessly to each other and to your Lexi Mobile App. They send and receive that information using protocols - which are a set of standards and rules that allow devices to understand each other.
Every smart product uses one or more different types of protocol, the more common and popular of which include WiFi, Bluetooth Low Energy (Le), Bluetooth Low Energy Mesh (BLe Mesh), ZigBee and Z-Wave. Each one has its own unique benefit.

We at Lexi realize that in order to make the system smart and usable for a variety of use cases, we cannot restrict ourselves to a single protocol. Hence, we use multiple protocols in our system. Currently, our devices use WiFi, Bluetooth Le, BLe Mesh and 900MHz radio.

The Lexi Hub should be located within WiFi range of your Router.
Stone, tile, mirrors, and large metal surfaces tend to interfere with wireless communication. Try to avoid placing your Hub in locations that put surfaces like these between the Hub and your connected devices.
If possible, locate your Hub in an open space at least 3 feet above the floor. Avoid cabinets when possible.
All the Lexi Devices utilize BLe Mesh as their core communications protocol. A mesh network is unlike a typical WiFi network, which is based upon a Star topology in which each device has to be within a specific range of the Hub. In a mesh network, each device acts as a transmitter as well as receiver for all the other devices so you can extend the range out almost indefinitely as long as each device is within 40 ft. of another device.

Yes. You can give access to your Lexi system to other users. Lexi utilizes a concept of a Super User, who acts as an admin for all other users on the system. As the Super User, you determine who has access to your Lexi system. As the master account user, you can add, edit, or remove their access at any time. You can simple share the Lexi hub with another user and they can get full access to your system.

Yes. You can configure Multiple Lexi Hubs in different locations. However, you can only control one hub at a time. If you want to control another Lexi Hub, simply click on Switch Hub in the Lexi Mobile App and select the Hub you wish to control.

The Lexi Hub utilizes WiFi to connect with your home’s WiFi Router. Your first step is to download the Lexi Mobile App on your mobile device and then configure the Hub. Power up the hub and start the Lexi Mobile App on your mobile device. Click on Add Hub, the Lexi Mobile App will start scanning for Lexi Hubs around you. Once it discovers one or more Lexi Hubs, it will display a list. You select the Hub you are interested in configuring. It will then ask for WiFi credentials of your local network and send the configuration to the Hub.

No, the Hub requires at least 1.2A to operate properly and Laptop USB ports max out at 900mA and often provide even less current than that.

Yes. However, please confirm that your Power Bank provides 5V@ 1A to 3A of power. Fortunately, this is standard for most Power Banks.

Yes. You can access, control, and automate your Lexi products from the Lexi Mobile App wherever you are, as long as you are connected to the Internet or mobile data.

While there is no limit to the number of devices you can connect, we recommend not more than 500 devices per hub.

We take our users’ privacy and data security very seriously, and we regularly examine our practices to ensure that they exceed industry standards.
The most important subsystem within Lexi is the Hub & Lights. Each Lexi customer is protected using a network key unique to every hub. When the Hub is installed, a unique network key is created and every device added subsequently uses this network key. This makes the system secure as no one can get access to this key.
Our cloud servers are secured using industry standard security measures like firewalls, private networks, key based authentication, code encryption, error handling, Public key infrastructure and SSL/TLS encryption. We also monitoring our infrastructure and conduct security audits using the industry leading security tools. For API access we use OAuth 2.0.

Battery Life will vary but should be between 6-12 months. The single largest variable in the determining the life of the battery in the MicroSensor is how often the Motion Detector is triggered. The less it’s triggered, the longer the battery life.
The MicroSensor uses the highest capacity Coin Cell battery available-the CR2477, which has 4X the capacity of the more commonly used CR2032. Don’t worry, your Lexi Mobile App and Cloud App will both alert you when the battery is low and ready for replacement. And you can set up automatic battery replacement through Lexi so you never have to worry!
