I have it on multiple devices, My cell phone {Samsung}, Samsung tablet, & my work PC & my son has it on his Apple phone & iPad. So yes it can be seen on many devices. We love our station it was so easy to set up & hook up to our network. Looking to put one at our vacation home also. 

1.If the camera's current Wi-Fi and Wi-Fi you want to switch can be connected at the same time, you can switch Wi-Fi directly by selecting Wi-Fi network in the settings interface. 2.When the camera is disconnected from the current WiFi, the app will display "Device disconnected". Click Troubleshoot to connect directly to another wireless network. Or remove the camera from the Tuya Smart and then connect the camera to the Wi-Fi you want to switch to.
