ctrl support

Before you connect

• The iOS app version 0.1.1 and later requires iOS or iPadOS 26.0 or newer. The Android app requires Android 8.0 or newer and a 64-bit ARM device with Bluetooth Low Energy.
• A compatible ctrl device is required for live status, routines and usage history.
• The current app supports the original ctrl Bluetooth protocol. Newer prototype firmware using a different protocol is not yet compatible. Contact us if you are unsure which firmware your device uses.

If your device does not appear

1. Check that the device is powered on, charged and ready for Bluetooth discovery.
2. Turn on Bluetooth in your phone’s settings.
3. On iOS, open Settings → Privacy & Security → Bluetooth and allow ctrl. On Android, open Settings → Apps → ctrl → Permissions and allow Nearby devices. On Android 11 and earlier, allow Location for Bluetooth scanning and turn on the phone’s Location setting.
4. Keep the device near your phone and retry connecting in the app. Disconnect it from other phones first if it is already in use.
5. If the app reports a missing service or characteristic, include that exact message when contacting support. It may indicate incompatible firmware.

When disconnected, the app may show the last saved snapshot. Connect and sync before relying on its displayed status.
