Hunter Hydrawise Controller Offline or No Internet Connection
- 2.4GHz band-steering on the router
- Router, ISP, or WiFi password changed
- Reached WiFi but not the Hydrawise server
Problem Description
Your Hydrawise controller shows offline or a No Internet Connection message in the app, or will not rejoin WiFi after a router change. It keeps running its stored schedule, but you lose app control and weather-based Predictive Watering until it reconnects to the Hydrawise servers.
Why This Happens in Real Homes
When Hydrawise is offline it keeps watering the stored schedule but loses app control and Predictive Watering, so it is not a dead controller. In real homes the usual causes are 2.4GHz band-steering on the router blocking the connection, and a router or password change leaving stale credentials behind.
Confirm a real 2.4GHz network, re-run the WiFi wizard, and reserve a static IP for daily dropouts. A solid WiFi icon on the controller does not always mean it actually reached the server.
Symptoms
- Controller shows offline in the app
- No Internet Connection message
- Will not rejoin WiFi after a router change
- Shows connected in WiFi settings but not to the server
- Drops offline about once a day
- App changes never reach the controller
- Cannot control zones remotely
- Weak signal at an outdoor controller
Recognize these? Here's what usually causes it.
Common Causes
- 2.4GHz band-steering on the router
- Router, ISP, or WiFi password changed
- Reached WiFi but not the Hydrawise server
- IP address reassigned daily by the router
- Weak WiFi at a garage or outdoor mount
- Stale saved credentials
- Router needs a reboot
- Controller needs a restart
Most fixes happen in the first 3 steps.
Step-by-Step Solution
Know what offline actually stops
When Hydrawise is offline it keeps watering the default schedule saved in the controller's own memory, but no Predictive Watering or weather adjustments apply, and any changes you make in the app only push to the controller once it reconnects. So an offline controller is not a broken one; the lawn still waters on the last synced program while you sort out the connection.
Confirm a 2.4GHz connection
Hydrawise controllers join 2.4GHz WiFi, and routers that merge 2.4 and 5GHz under one name with band steering often stop the controller connecting, which is a known problem on some ISP gateways. Split the bands or set up a separate 2.4GHz network name, then reconnect the controller to that band in its WiFi wizard so it has a clean 2.4GHz network to hold onto.
Restart the controller and the router
Unplug the Hydrawise controller for about 15 seconds and plug it back in, then reboot the router by unplugging it for 10 seconds. This clears a controller that shows connected in its own WiFi settings but never actually reaches the Hydrawise server, which is the usual gap behind a No Internet Connection message even when the WiFi icon looks fine.
Re-run the WiFi wizard after a router change
If you changed router, ISP, or WiFi password, the saved credentials no longer work and the controller drops offline. On the controller, open the WiFi settings and run the connection wizard again to select your network and enter the new password. A router or password change always requires re-entering the credentials; the controller cannot pick up the new ones on its own.
Reserve a static IP for daily dropouts
A controller that connects and then drops off every day often has its IP address reassigned by the router. In your router settings, reserve a fixed IP for the Hydrawise controller, or set a static IP on the controller, so it keeps the same address and stays reachable. Several owners have cured a controller that goes offline once a day this way.
Check signal and let it settle
An outdoor or garage-mounted controller may sit at the edge of WiFi range, so move the router or add a mesh node closer if the signal is weak. After a successful wizard run, give it time, since a freshly linked Hydrawise sometimes takes a while, even overnight, to fully register as online. If it still will not connect, Hunter has Hydrawise connection articles at support.hydrawise.com.
Quick Solutions
Still having issues? This is usually the deeper cause below.
This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.
A solid WiFi icon in the controller's own settings does not always mean it reached the Hydrawise server, so trust the app's online status over the local WiFi indicator. Because the controller keeps watering its stored program offline, there is no rush that risks your lawn while you work through the connection.
Most WiFi drop-offs happen right after a router reboot or ISP swap — the device reconnects to the network but silently loses its cloud registration.
