You may notice that your Lumo device is offline in several different ways;

An alert when attempting to schedule an irrigation when a device offline
If so, you'll want to troubleshoot why the device is offline. Follow the steps below:
Step 1: Verify that the base unit is online
First, confirm in the Ops Center that the base unit is online. If the base unit is offline, the Lumo system is not connected to the internet, and all valves and relays will show as offline regardless of their health.
Login to the Ops Center
Navigate to the Devices page
Filter your search by Farm and Type (Base)
Verify the Status
If the Base unit is offline:
Verify that the base unit is plugged into an electrical outlet
Verify that the electrical outlet is hot (providing voltage) by plugging in another device, or using a receptacle or non-contact voltage tester
Restore power to the outlet if no voltage is measured. Wait 5-10 minutes, then check the base unit’s Status in the Ops Center again (the base unit may take up to 10 minutes to reconnect to the cellular network)
If these steps do not resolve the issue and the base unit remains offline, contact Lumo Support
Step 2: Determine if any other devices are also offline
Next, check the Ops Center to see if any other Lumo devices in the farm network are offline. This step is important to confirm whether there is an issue with the particular valve or relay you’re addressing, or whether there is a confounding connectivity issue with another device.
Because Lumo valves rely on a daisy-chained telemetry network, one offline device may cause a linked device(s) to also be offline. The solution may actually be to troubleshoot the other affected device first, depending on its proximity to the base unit or other valves/relays.
Step 3: Check The connectivity status LED on the offline device
Examine the Connectivity Status LED next to the Control Button to determine the current status of the valve or relay.
Solid Green | Device is syncing with the network → Device should show as online in the Ops Center |
Flash Green (rapid) | Device is attempting to connect to the WiFi network → Device is offline, but functioning |
Slow Pulse Green | Device is sleeping between sync cycles → Device should be online, but is not currently sending data |
Not illuminated | Device is powered off or has 0% battery |
If the Connectivity Status LED illuminates blue, the device is in Installation Active mode, but the indicators (solid, flash, pulse) are the same as Standard Mode (green LEDs) listed above.
Step 4: Check the device for responsiveness
Press the Control Button once. The Valve Status LED should illuminate blue when the button is pressed. The dome may reboot after the button is pressed. In this case, both LEDs will blink white, then the Connectivity Status LED will flash to indicate that the valve is searching for the WiFi network. The LED will become solid once the valve has connected to the network.
If no LEDs illuminate when the Control Button is pressed, skip to step 6.
Step 5: visually inspect antenna and cable
Check the antenna and antenna cable for damage and corrosion. Ensure both the antenna is properly connected to the cable atop the pole, and that the cable is properly connected to the dome.
Ensure the antenna is vertically upright
Verify cable connectors are properly seated and tight
Confirm the antenna has line of sight to another Lumo device
Clear any plant material that may be interfering with the antenna
After tightening any loose connections and replacing any damaged parts, check connectivity again via the Connectivity Status LED and the Ops Center. If the device remains offline, proceed to step 6.
Step 6: Power cycle the Valve on and off
Follow these instructions to power cycle the dome.
After power cycling, watch the Connectivity Status LED to see if the device reconnects to the WiFi network, and verify its online status in the Ops Center. If connectivity has been restored, the device should display as online.
If the device remains offline, the dome may need to be replaced. Please contact Lumo Support.
