Should I buy "SafeWander Sensor" or "SafeWander Sensor + Gateway"?
The SafeWander sensor can be used with or without the Gateway.
If your smartphone or tablet is in the same room as the Sensor, they will communicate via their built-in Bluetooth. Therefore, you do not need to buy a Gateway. WiFi is not required either.
If you monitor from a different room (or anywhere), you will need to buy a Gateway and place it close to the Sensor to relay the Sensor signal to your phone/tablet via WiFi and Internet. WiFi is required to use the Gateway. Click HERE for our SafeWander Sensor + Gateway system.
