Locate the Hi-Smart Air home appliance as close to the wireless
router as possible. If the WiFi signal strength is weak, the Hi-Smart
App and WiFi module may be disconnected depending on the WiFi
signal strength. Check that no metal objects are attached to the
Hi-Smart appliance, or otherwise interfering with the WiFi signal.
D. Other Requirements and Precautions

when it is paired to the Hi-Smart Air home appliances for the first
time;
* When using the Hi-Smart Air Application, cellular data use may
generate expenses if the mobile phone is connected with 3G/4G data
