Level Sense (by Sump Alarm Inc) is a great way to monitor your sump pump remotely r with voice and text notifications. The purpose of this article to help users troubleshoot wifi enabled sump pump alarms that occasionally go "offline" (i.e. lose internet connection).
The article (and blog) was inspired by a customer that has two wifi enabled pump alarms in their home, and had them go "offline" at different times. So this article is general troubleshooting information about items that are "in the home" and on the same network.
The difference between monitoring a sump pump and any other item in home automation is the location. Why would it work most of the time but occasionally go off line? It's important to find the root cause of the problem:
- Signal Strength: This can be tested and determined if it the root cause the sump pump alarms offline state. A separate article has been dedicated to testing the signal strength at your device.
- Use of a VPN (Virtual Private Network) in the home. A VPN network may be provided by an employer to make a secure connection with the employers network and can cause other items on the same network to lose connectivity to the internet. If offline notifications arrive when a VPN network is in use, this may be the culprit. Here awareness is the key, and your notice of a pump related incident will be the siren on the unit.
- Router Device Limits: Many wireless routers have a setting or manufacturers limitation on the number of wifi connected devices that can be online. This is router dependant. Your router will have an IP address such as 192.168.1.1 where all router settings can be seen and reviewed. In these scenarios the router has a limited number of IP addresses it can issue, and putting a new device online may bump another device off. Check the router settings. The solution is to increase the number of allowed devices in the router, or a new router. If the router is maxed out, its maxed out, and the problem will need to be dealt with anyway as wireless devices in the home are only increasing.
- Router Prioritization: Newer routers can prioritize what data flows through them. The kids get on XBOX and Netflix, and the router sees that those connections are using the most data, and makes them the priority. This can also be modified in the router settings to give priority to the WiFi connected sump pump alarm in the router settings.
- Router Self Healing: Some routers may be set to restart itself periodically. Often this will be at midnight of a set day of the week. This is correctable in the settings, but the easiest fix to this is either to ignore the notifications on that particular evening, or increase the device offline threshold (the time duration before the notifications are sent out) on the website to 10 or 15 minutes. This gives the device time to fully reset and put all the wireless devices (including the sump pump alarm) back online before the notification goes out.
- Wi-Fi extenders: Wi-Fi extenders are a great tool. Most Level Sense customers are sending data on a two minute interval. If the wifi extender periodically loses connection with the main router, or falls victim to any of the self healing, or prioritization causes above, or resets itself periodically, the solutions will be the same as 5.
- We're doing maintenance. If this is the cause the cloud light on the device will blink purple - not blue or red. In that case - it's not the local network - it's us!
