An offline Hydrawise controller has lost cloud communication; that does not automatically mean the valve hardware failed. Confirm the controller has power, check whether local touchscreen watering works, restart the router, then use the controller's wireless status and reconnection flow. Save factory reset for last because it removes configuration.
Match the pattern before opening anything
| Possible cause | Best clue | First check |
|---|---|---|
| Router or internet outage | Other devices also lost internet | Restart modem and router |
| Weak or blocked signal | Controller reconnects near an access point | Check signal at the enclosure |
| Changed Wi-Fi credentials | Problem began after router replacement | Run wireless setup again |
| Account or serial-number link | Local control works but app control does not | Verify the controller is linked to the account |
What this guide adds beyond the standard checklist
- First dividing test
- Check power and local control: Confirm the controller screen is stable and run one short zone test from the controller. If local watering works, irrigation hardware is separate from the connection problem.
- If the clue matches
- If you observe “Other devices also lost internet,” move router or internet outage higher on the list and start with: Restart modem and router.
- If it does not
- If that clue is absent, do not force the first diagnosis. Compare the system against “Controller reconnects near an access point” and check: Check signal at the enclosure.
Worked exampleYou restarted the Hydrawise controller, but it went offline again within a day. The result changes the next move: Check signal at the enclosure, restart the router, and reconnect using the current network credentials.
Original conclusionA temporary restart does not correct weak signal, router steering, interference, or stale Wi-Fi credentials. Check signal at the enclosure, restart the router, and reconnect using the current network credentials.

Check these in order
- 01
Check power and local control
Confirm the controller screen is stable and run one short zone test from the controller. If local watering works, irrigation hardware is separate from the connection problem.
- 02
Test the network with another device
Stand near the controller with a phone and confirm the intended Wi-Fi network has internet access. Metal enclosures, masonry, basements, and long distances can weaken the signal.
- 03
Restart the network before erasing settings
Power-cycle the router and any extender, allow them to finish reconnecting, then recheck Hydrawise. This preserves controller programming and often fixes a temporary lease or access-point problem.
- 04
Reconnect with current credentials
If the network name or password changed, use Hydrawise's supported wireless setup. Verify you are linking the correct controller serial number to the correct account.
- 05
Use factory reset only as the final branch
A factory default removes configuration. Photograph zone assignments and confirm account details first. If the controller cannot see a usable network after signal and credential checks, contact Hunter support before erasing it.
- The controller also loses power or local zone control.
- The installation is inside a metal enclosure with no practical network path.
- Reconnection fails after confirmed signal and credentials.
What homeowners ask about this symptom
Will Hydrawise watering stop when Wi-Fi goes offline?
Offline behavior depends on controller configuration and stored schedules. Treat local controller status as authoritative and restore connectivity so weather data, remote control, and history can update.
Should I factory-reset an offline Hydrawise first?
No. Start with power, local control, router, signal, credentials, and account linking. Reset can erase configuration without solving weak Wi-Fi.
