Bosch EasyControl displays error C13 and reports that geofencing or presence detection is unavailable.

Safety first: No electrical risk; this is an app/service configuration issue.

• 1. Enable location services: On your smartphone, ensure that location services are turned on and that the Bosch EasyControl app has permission to access location "Always" or "While Using" as required.
• 2. Update the app: Install the latest version of the Bosch EasyControl app from the official app store.
• 3. Check account and device link: Ensure that the phone is logged into the same Bosch ID account that owns the EasyControl and that presence detection is enabled in the app settings.
• 4. Test with another phone: Add a second user/phone to the household in the app and see if presence detection works for that device.

Professional help: If C13 persists across multiple phones and networks, contact Bosch support to check for backend service issues.
