TinyWatch needs a local path between the room iPhone and the device showing the live view. Connecting both to the same home Wi-Fi is the simplest starting point. A matching network name isn't a guarantee, though, because a router can keep connected devices isolated from one another.
Check the network on both devices
Open Wi-Fi settings on the room iPhone and the viewing device. Both should show the same active network name. If you want to rule out a cellular fallback on the viewing phone, temporarily turn off cellular data while you test.
On a Mac, select the Wi-Fi icon in the menu bar. On Windows, open the network controls from the taskbar. A computer connected by Ethernet to the same router may also work, as long as the router doesn't separate wired and wireless devices into isolated networks.
Why matching Wi-Fi names may not be enough
Guest networks often prevent connected devices from talking to each other. Hotel, school, workplace, and public Wi-Fi may use the same kind of isolation. In that case, the QR code can be valid while the network blocks the actual local connection.
A VPN, firewall, security filter, or router option named client isolation, AP isolation, or wireless isolation can have a similar effect. Don't disable security settings at random. First move both devices to a private network you control and see whether the live view opens there.
Troubleshoot in a useful order
- Confirm that TinyWatch is still running in the camera role on the room iPhone.
- Check the active network name on both devices.
- Confirm camera, microphone, and local-network permissions on the iPhone.
- Pause the VPN for the test if your device policy permits it.
- Create a fresh viewing link or QR code and open it again.
- On a computer, try a current Chrome version if Safari doesn't open the view.
- Restart TinyWatch and the browser, then the router if the earlier checks didn't help.
Change one thing at a time. That tells you whether the cause was network access, a permission, the browser, or an expired session.
Can a personal hotspot help?
A personal hotspot creates a temporary Wi-Fi network and can be useful away from home. The exact result depends on which device provides the hotspot, which iPhone acts as the camera, the carrier, and operating-system behavior. A hotspot can also disconnect when devices sleep.
Don't rely on a generic recipe without testing your exact arrangement. Rehearse it before a trip and test reconnection after the screens sleep. Apple lists current behavior and limitations in its Personal Hotspot guidance.
Local video doesn't mean every step is offline
The room media travels locally between the devices. Opening the handoff page and sharing the viewing link can still involve tinywatch.app, so we don't describe the whole product as guaranteed to work without internet access.
Treat the link as access to the current session. Don't post it or send it to anyone who shouldn't view the room. Create a new session if a link was shared in the wrong place.
Test the behavior you will actually use
Once connected, check video, audio, and what happens when the viewing window is minimized or the screen locks. Browser motion and sound alerts require the page to stay open and visible. Use the Mac app versus browser guide if you plan to keep the view beside your work.
TinyWatch is for nearby room check-ins and doesn't replace direct adult supervision. A network, power, permission, or device-state change can end the session. Keep the room iPhone, mount, charger, and cords outside the child's reach.
