I was recently directed to the Zigbee Child and Routing Info table at the link below. Seems like this would help me troubleshoot some weird intermittent problems I have been having with my Zigbee network but I am not entirely sure what I am looking at.
This is a spill of what I am getting from the http://HUB_IP_ADDRESS/hub/zigbee/getChildAndRouteInfo link.

I am looking for some help filling in the gaps. Here is what I already know from searching existing forums.
-
LQI (Link Quality Indicator?) is really the most important metric and the 255 is perfect. Anything above 200 is considered good.
-
Age is the number of 16 second cycles that have passed since the device has checked in. After 64, the record is eligible to be purged from the routing table.
It seems that there is a lot of additional useful info here but is a bit of a mystery to me. Here are some of my questions.
-
What are incost & outcost. I am assuming these are path costs but I am looking for info on how they are determined and applied.
-
Why does this page show such a small subset of my devices? I have around 110 Zigbee devices on my network.
-
The device with the poor LQI is actually working just fine. If it is working fine, do I still need to take steps to increase the LQI?
-
Null records everywhere. I have a bunch of "null" records. These seem to pop up randomly in both the route table and occasionally in the neighbor table. I read in another thread that these are nodes that think they are supposed to be on the network because they were never properly removed/reset. That would make sense except my network is only a few months old and I don't have any devices floating around that would fit this description. Also, they seem to be constantly changing ID's. In my mind, these things are what is messing up my network but I have no idea what they are, where they are from, or how to get rid of them.
-
Loop Route? I see routes from time to time where a device is routing through itself. How is this possible? Is this causing problems?
-
Why are the numbers on this table different from the numbers on the Zigbee Logging page under the Zigbee settings? I have one node that has a relatively poor LQI on this table but shows a last hop LQI of 255 on the logging page.
-
Anything else that would help me understand what I seeing would be great!
