• Cypress temperature: The metal ring of the first-generation Cypress sensor is the heat sink of the
CPU. Therefore its temperature is a bit hot, but the tempratures of other parts of the sensor are
normal, and the sensor meets the safety standard.

• Verification Email: If you could not receive the verification email after registering a new
account, please check if your email is spelled correctly, and also check the junk folder of
your email account.
• Firmware and App Versions: Please always use the latest firmware and app versions. Some
new features in the firmware (or App) may not work with an old App (or firmware).
• App Permissions: The Sentinare App needs certain permissions to work properly. When you
first use the App and some of its features, it will ask for the following permissions. Please
allow these accesses when the App is running. These permissions can be changed in the
Setting page of your mobile device.
o Push notification
o Bluetooth
o Location (required to use Bluetooth)
o Local Network (required to use voice call)
o Microphone
o Camera
• WiFi Protocol: For security reason, only secure WiFi networks with WPA2-PSK (or WPA2-
Personal) protocol are supported. Open, WEP, WPA, and WPA2-Enterprise are not supported.
The WPS (Wi-Fi Protected Setup) setting should be disabled. See the Setup WiFi section in
Sec. 4 for details.
• Whitelist: When you try to add a sensor to your account, if you get an error message stating
that the sensor is not in the whitelist of the server, it means that the sensor is registered in
a different server from the server that your user account is registered. You need to register
your account in the correct server. Currently, three servers are available, in US, Canada, and
China. If you are in these countries, your sensor is default to your country’s server. If you
are in other countries, your devices are usually registered in the US server, unless we notify
you otherwise.
