The Kami app guides you through the installation process with some helpful video tutorials that show every step of the process. Each device comes with a QR code that makes it easy to add to your system using the Kami Home app. Thankfully, the process for installing is so simple that the videos are enough, because there isn't much information beyond these videos.
It takes around 10–15 minutes to set up the base station, connect the sensors, and place equipment. Each Kami sensor comes with an adhesive backing that makes them easy to place on a wall, door frame, or window frame. You can also use screws to mount the sensors for easier removal (sensor adhesive can be hard to remove). According to YI, the batteries in the detectors will last up to a year.
YI's customer service seems to be all over the place. When we looked at the company's support website, we found some decent information about Kami Smart Security, though it was incomplete.
For example, we couldn't find any information about smart home compatibility or the 24/7 Emergency Response service on the support website. After some digging, we found this information in the YI Community Hub, a forum for customers to ask questions.
The community forum is more helpful than the support page, but it's also incomplete. This disorganization makes for frustrating troubleshooting unless you have a razor-sharp focus to know what you're looking for. We can only imagine how that affects regular customers wanting help if seasoned security experts such as ourselves have trouble finding solutions.
YI's equipment comes with a one-year warranty, which is pretty standard among technology companies. If you need help with your devices, we suggest posting in the community forum or sending an email to customer support. The company's phone support is temporarily unavailable due to the COVID-19 pandemic.
