3. Update the Switch Firmware:
Once your smartphone application is updated, it may request a firmware update for the physical switch.
Inside the app, tap on your Retrotouch switch, tap the Edit / Pencil Icon in the top-right corner, scroll down, and tap Check for Firmware Update. If an update is available, tap Update Now. Do not turn off your home router or the lighting circuit breaker while this digital flash is processing.
3. Resolving Common Update Glitches
"Device Unbound" or Switch Disappeared Post-Update
On rare occasions, when an app undergoes a massive structural version update, security certificates can refresh, which may log you out of your secure user token profile.
The Fix: Do not reset your physical switches. Simply log completely out of your account profile menu inside the app, close the app, open it again, and log back in with your original email and password. Your switches and custom room configurations will pull right back down from the cloud server.
App Intermittently Freezes on the Control Dashboard
If your application lags when toggling switches on or off after a phone operating system update (such as migrating to a new iOS or Android version), background smartphone system settings are likely sandboxing the application.
The Fix: Go to your smartphone's system Settings menu, scroll down to the app list, select your smart home app, and verify that Local Network Access, Bluetooth, and Background App Refresh are all fully enabled. This gives the app permission to process instant data exchanges with your router.
