LinknLink App can provide remote control for supported Home Assistant devices after LinknLink Remote is installed and configured. The initial Home Assistant service setup requires your phone and Home Assistant to be on the same local network. After LinknLink Remote is configured, test the same device on local Wi-Fi and then over mobile data such as 4G or 5G.

Troubleshooting / Notes
Use these checks to review the setup in the same order as the guide:
- If the Running status does not appear, review the LinknLink Remote installation and Configuration steps in Home Assistant.
- If you cannot add the HA service, confirm that your phone and Home Assistant are on the same local network during the initial setup.
- If the token is not accepted, repeat the Create token and Copy steps, then paste it into the User Token field and save it.
- If an HA device does not respond, confirm that it was added in LinknLink App, reselect it from the device list, and test it on local Wi-Fi first.
- If no Remote HA host is selected, return to LinknLink Remote settings and select the intended host.
- If the green Remote indicator does not appear, check Enable LinknLink Remote, Remote HA host, the selected HA service, and Save.
- If local Wi-Fi control works but the 4G/5G test does not, review the Remote configuration and repeat the mobile-data test with the same selected device.


Test Remote Control on Local Wi-Fi and Mobile Data
Use the same selected device for both checks so you can distinguish local setup from remote configuration.
- Keep your phone connected to the same local Wi-Fi network as Home Assistant.
- Open the device list in LinknLink App and select the device you added.
- Test a simple control action, such as turning a lamp on or off.
- Turn off phone Wi-Fi while leaving the Home Assistant system connected to its network.
- Keep the same device selected and repeat the control action over 4G or 5G mobile data.
- Use the setup checks above if the local and mobile-data results differ.
The source tutorial uses a lamp as the example device. Device availability and control behavior depend on the device added to your Home Assistant service.
