My Smart Power Plug Shows Offline

Overview

Seeing "Offline" next to your smart power plug in the Shipshape app can feel alarming, especially if it is monitoring something important like a sump pump or water heater. The good news is that offline does not always mean your appliance has lost power. It means the plug has stopped talking to your Shipshape gateway.

The plug sits between your appliance and the wall outlet, tracking energy usage and reporting data back to SAM. There are two reasons it goes offline: it lost its connection to the gateway, in which case power still flows to your appliance, or the plug itself has no power (it was unplugged, or the outlet or breaker tripped), in which case your appliance has no power either.

This guide will help you figure out why your plug lost its connection and how to get it back online.

What "Offline" Actually Means

When a smart power plug shows offline, it means one of the following happened:

• The plug lost its wireless connection to the gateway. Shipshape power plugs communicate with the gateway over Z-Wave, a short-range wireless protocol. If something disrupts that signal, the plug appears offline.
• The gateway itself is offline. If the gateway cannot reach the internet, every sensor and plug in your home will show offline.
• The plug lost power. If the outlet it is plugged into lost power (tripped breaker, tripped GFCI outlet, switched outlet turned off), the plug will go offline because it has no power source of its own.
• The plug was unplugged. We often see this when other contractors working in the area need the outlet for something else.
• The plug experienced a temporary glitch. Wireless devices occasionally lose their connection. Most reconnect on their own; some need a quick reset.

The important thing to remember: offline is a communication status. Check the outlet (Step 4) to know whether the appliance still has power.

Step-by-Step Troubleshooting

Follow these steps in order. Most issues resolve within the first three steps.

Step 1: Check Your Gateway Status

Open the Shipshape app and look at your gateway status. If the gateway itself shows offline, that is your problem. All of your sensors and plugs depend on the gateway to relay data.

• Look for the gateway status indicator in the app. A green indicator means online and healthy.
• If the gateway is offline, see our Gateway Is Showing Offline guide before troubleshooting individual plugs.
• If the gateway is online, move to Step 2.

Step 2: Check the Distance and Range

Aeotec rates the Smart Switch 7 plug at up to about 115 ft (35 m) indoors, but walls, floors, large metal appliances, and concrete can reduce that range significantly.

• Is the plug in a basement or utility room far from the gateway? Distance is the most common range issue.
• Are there thick walls, metal ductwork, or concrete between the plug and gateway? These materials absorb wireless signals.
• Did anything change recently? New furniture, a relocated gateway, or even a large metal shelf can block the signal path.

If range seems like the issue, a Z-Wave range extender placed between the plug and the gateway can solve it. Some Shipshape power plugs also act as range extenders for other devices, so adding another plug in between can help.

Step 3: Toggle the Plug Off and On

Give the plug a quick reset by pressing its physical button:

1. Locate the smart power plug where it is plugged into the wall outlet.
2. Press the button on the plug once to turn it off. You should see the LED indicator change.
3. Wait about 5 seconds.
4. Press the button again to turn it back on.
5. Wait 1 to 2 minutes for the plug to reconnect to the gateway.
6. Check the app to see if the plug now shows online.

Turning the plug off also turns off the appliance on it. If it powers a sump pump or a freezer, turn it back on right away.

Step 4: Check That the Plug Is Plugged In and the Outlet Has Power

It sounds basic, but it is worth confirming:

1. Make sure the smart plug is still plugged into the wall outlet, and your appliance into the smart plug.
2. Unplug the smart plug from the wall outlet.
3. Plug in something simple, like a phone charger or lamp, to verify the outlet has power.
4. If the outlet is dead, check your electrical panel for a tripped breaker. Flip the breaker fully off, then back on.
5. If the outlet has TEST and RESET buttons (a GFCI outlet), it may have tripped. Press RESET.
6. Some outlets are controlled by a wall switch. Make sure the switch is in the "on" position.
7. If the outlet has power, plug the smart plug back in and wait 1 to 2 minutes for it to reconnect.

Step 5: Move a Range Extender Closer

If the plug keeps dropping offline and distance seems to be the issue:

• Place a Z-Wave range extender roughly halfway between the gateway and the troublesome plug.
• Alternatively, if you have another Shipshape smart plug, plug it in at a midpoint location. Smart plugs act as repeaters in the Z-Wave mesh network.
• After adding a range extender, run Optimize Network in the app (Manager > Manage Network > tap the gateway > Details). It can take up to 15 minutes, and you can't add or remove devices while it runs. See Aeotec Range Extender 7.

If the Plug Monitors a Critical Appliance

Some appliances are too important to leave unmonitored. If your smart plug monitors a sump pump, freezer, or water heater, take these extra precautions:

• Manually verify the appliance is running. Go to the appliance and confirm it is operating. Listen for the hum of a motor, feel for warmth on a water heater, or check that a freezer is cold inside.
• Do not wait to troubleshoot. If the plug monitoring your sump pump goes offline during heavy rain, verify the pump manually right away.
• Consider a backup notification plan. Talk to your service professional about placing the gateway closer to critical appliances or adding a dedicated range extender for the sump pump area.

Getting these plugs back online quickly is important for your peace of mind and your home's protection.

Tips for Preventing Future Offline Issues

• Keep the gateway in a central location. The closer it is to the center of your home, the better coverage your Z-Wave network will have.
• Avoid placing the gateway inside metal cabinets or behind large electronics. These can shield the wireless signal.
• Use the mesh network to your advantage. Each powered Z-Wave device (like a smart plug) extends the network. More plugs in your home means better coverage for all of them.
• Check the app periodically. SAM will alert you when devices go offline, but a quick glance at your dashboard once a week helps you catch any lingering issues.

When to Contact Support

Contact Shipshape support if:

• The plug remains offline after completing all the steps above.
• The plug goes offline repeatedly (more than once a week) despite being within range.
• The LED on the plug is not lighting up at all, even when plugged into a working outlet.
• You suspect the plug itself may be defective.

When you contact support, have the following ready:

• Your home address or account name
• Which appliance the plug monitors
• The location of the plug in your home (e.g., "basement, next to sump pump")
• What troubleshooting steps you have already tried

If a plug keeps losing its connection to the gateway, contact Shipshape support and we'll send you a network repeater. It helps stabilize your Shipshape network. See Aeotec Range Extender 7.

Shipshape support can check when the plug last reported and its signal to help diagnose the problem faster.
