You may have two slightly related problems. If your leak detector has missed a check in there are usually 3 possible causes and solutions:
Changed Wi-Fi network information
You've changed your Wi-Fi network name or password. If this is the case you will need to set up your device again.
Intermittent internet connection
Your internet was not functioning correctly when the leak detector tried to check in. Resetting your Wi-Fi router by powering it off, waiting 30 seconds, and then powering it back on usually helps resolve this type of issue.
Low Wi-Fi signal strength
The Wi-Fi signal strength in the location where you have your leak detector may not be adequate. Low Wi-Fi signal strength is the most common reason that a leak detector misses a check in.
Using your smartphone that is connected to the same Wi-Fi network as your leak detector, place the smartphone right where your leak detector is located. Observe the Wi-Fi signal strength. Make sure that this signal strength is average or above. If not, you may not have adequate Wi-Fi signal strength for your leak detector where it is located.
You can often extend the range of your Wi-Fi network by installing a Wi-Fi extender or moving your Wi-Fi router to a location closer to where you want to place your leak detector.
Low battery level
Your leak detector will continue to check in with a low battery level, unless something happened to drain the battery level quickly. You will need to replace its AAA batteries at your earliest convenience. Please see our Help Center article: My leak detector shows low battery level
