eufyCam S3 Pro Offline? Here’s How to Fix It
When your eufyCam S3 Pro shows as offline it has lost its connection, so you can’t see Live View, get alerts or record new clips in the eufy Security app.
What This Problem Means
If your eufyCam S3 Pro is showing this fault, working through the checks below in order resolves it in the large majority of cases. Each step is safe to try yourself and follows eufy’s official guidance.
Common Symptoms
- Camera shows offline in the eufy app
- Live View won’t load
- No motion notifications
- Greyed-out thumbnail
Safe Checks You Can Try
1. Restart everything
Reboot the camera and the HomeBase. To reboot the HomeBase, unplug its power adapter (and Ethernet cable) for about 30 seconds, then reconnect. Restart your router by unplugging it for 30 seconds too. This clears most temporary glitches.
2. Check your internet
Confirm other devices can reach the internet. eufy cameras and HomeBase use 2.4GHz Wi-Fi, so if your router merges bands under one name, separate them or connect to the 2.4GHz band.
3. Check the signal
A weak Wi-Fi signal where the device sits is the most common cause. Move it closer to the router or HomeBase, or add an extender.
4. Confirm the network hasn’t changed
If you changed your Wi-Fi name or password, the device will go offline. You will need to remove it from the app and run setup again.
5. Re-add the device
In the eufy Security app, remove the offline device and add it again. Back up any footage first.
6. Check the HomeBase
Make sure the HomeBase is online first — if it is offline, every paired camera shows offline. Check its LED and Ethernet connection.
