How to diagnose and resolve issues causing Weak Signal alarms.
This alarm is raised when more than 75% of readings from the device have a weak signal over a three-hour period. If you see this alarm on one of your devices there are a few things you should check.
It is possible that the device is still sending data normally, even with a weak cellular signal. First, check whether the device is sending consistent readings over time. To do this, check the Activity section under Devices > Nodes > Status Details. If you see the expected number of readings, no action is needed.
Example activity plot. Based on the Sleep Time, we expect this device to send between 3 and 4 readings per hour.
If there are fewer readings than expected, there are a few other troubleshooting steps it may be helpful to take:
- Power cycle the Node-S. To do that:
- Unplug the solar panel or power adapter from the Node-S power connector
- Wait 30 seconds, and plug it back in - screwing the connector's ring firmly in place
- Listen for the Node-S Power On sound and Connection Successful sound
- If after power cycling the node you hear a Low Battery sound instead, please charge the device for at least 24 hours
- If after power cycling the node you hear the Power On sound but not the Connection Successful sound:
- Check that the antenna is securely attached
- If possible, relocate the device to an area with stronger cell reception
- It is often helpful to test whether the Node-S connects successfully inside your office or in a place where you know there is good cell reception
