Device Shows Offline

Step-by-step instructions to get your PlumBuddy device back online when it stops connecting.

Why Your Device Shows Offline

When your PlumBuddy device shows “Offline” in the app, it means the device has lost communication with PlumBuddy’s servers. This does not necessarily mean something is wrong with the device itself. The most common causes are WiFi issues, power interruptions, or the device being too far from your router.

Work through these steps in order. Most offline issues are resolved in the first two steps.

Step 1: Check Your Home Internet

Before troubleshooting the device, make sure your home internet is actually working.

  1. On your phone, connect to the same WiFi network your PlumBuddy device uses.
  2. Open a web browser and try loading any website.
  3. If the website loads, your internet is fine — move to Step 2.
  4. If the website does not load, your internet is down. Contact your internet service provider. Your PlumBuddy device will reconnect automatically once internet service is restored.

After a Power Outage

If your home recently lost power, your router may take several minutes to fully restart and reconnect to the internet. Wait 5 minutes after power is restored, then check if the device comes back online on its own.

Step 2: Power Cycle the Device

A simple power cycle fixes most offline issues, especially after WiFi interruptions or brief power outages.

For PlumBuddy Valve:

  1. Unplug the USB-C power cable from the valve.
  2. Wait 30 seconds.
  3. Plug the cable back in.
  4. Wait up to 2 minutes for the device to reconnect.
  5. Check the app to see if the device shows as online.

For PlumAssist Puck:

  1. Remove the battery from the sensor.
  2. Wait 10 seconds.
  3. Reinsert the battery.
  4. Wait up to 1 minute for the sensor to reconnect.
  5. Check the app for the sensor’s status.

Step 3: Check WiFi Signal Strength

Your device needs a reliable 2.4GHz WiFi signal to stay connected. If the device is far from your router or separated by walls, floors, or metal obstacles, the signal may be too weak.

Signs of Weak WiFi Signal

  • Device goes offline and comes back repeatedly
  • App shows the device online intermittently
  • Commands (open/close valve) take a long time or time out
  • Device worked fine initially but started dropping off over time

How to Improve WiFi Signal

  • Move your router closer to the PlumBuddy device if possible.
  • Add a WiFi extender or mesh node near the device’s location. This is the most reliable fix for signal issues.
  • Remove sources of interference. Microwave ovens, baby monitors, cordless phones, and some LED dimmers can interfere with 2.4GHz WiFi signals.
  • Reduce obstructions. Metal ductwork, concrete walls, and large appliances between the router and device weaken the signal significantly.

Checking the Distance

PlumBuddy devices should be within about 100 feet of your WiFi router. However, walls, floors, and obstacles reduce effective range. In a multi-story home with the router upstairs and the device in the basement, 50 feet of actual distance might behave like 150 feet due to obstructions.

Step 4: Reset the Bluetooth Connection

If the device went offline after a failed pairing attempt or a firmware update, the Bluetooth connection state may be stale.

For PlumBuddy Valve:

  1. Press the On or Off button on the valve to exit pairing mode (the rapid blue and green flashing will stop).
  2. Wait 10 seconds.
  3. Press and hold both the On and Off buttons together until the indicator light flashes blue and green. This puts the valve back into pairing mode.
  4. Open the PlumBuddy app and attempt to reconnect the device.

For PlumAssist Puck:

  1. Remove the battery.
  2. Wait 5 seconds.
  3. Reinsert the battery.
  4. Press and hold the small black button until the light blinks red.
  5. Open the PlumBuddy app and attempt to reconnect.

Step 5: Verify Your WiFi Network Has Not Changed

Your device will go offline if anything about your WiFi network has changed since it was set up. Common changes include:

  • Changed WiFi password
  • Replaced your router or switched internet providers
  • Changed your network name (SSID)
  • Switched from a combined band to split 2.4GHz/5GHz networks (or vice versa)

If any of these have changed, you will need to reconnect your device to the new network:

  1. Open the PlumBuddy app.
  2. Go to the offline device’s settings.
  3. Select Reconnect WiFi.
  4. Follow the on-screen steps to connect the device to your current 2.4GHz network.

Step 6: Full Device Reset (Last Resort)

If none of the above steps work, a full device reset clears all connection state and lets you start fresh.

For PlumBuddy Valve:

  1. Unplug the USB-C power cable.
  2. Wait 60 seconds for the internal capacitor to fully discharge.
  3. Plug the cable back in.
  4. Wait for the device to power up completely.
  5. Press and hold both the On and Off buttons until the indicator light flashes blue and green.
  6. Open the PlumBuddy app and set up the device as if it were new.

For PlumAssist Puck:

  1. Remove the battery.
  2. Wait 60 seconds.
  3. Reinsert the battery.
  4. Press and hold the small black button until the light blinks red rapidly.
  5. Open the PlumBuddy app and set up the sensor again.
