Understanding Zigbee warnings "TXStatus.NWK_ROUTE_DISCOVERY_FAILED"

[gilbert-grape]

Hello

I see in my logfile these warnings:

Can somebody explain me how to interprete these warnings? How do I find out, which sensors are not reachable? How do I make the link between “0x3F59:1:0x0006” and my sensor?

Thanks for helping
Gilbert

The “Route discovery failed” error means:

# An attempt to discover a route has failed due to a reason other than a
# lack of routing capacity

Which is not terribly helpful.

It does suggest, though, that your network is fine in terms of number of routers etc. You might start by looking for sources of interference. There’s a very thorough post about that here:

Zigbee networks: how to guide for avoiding interference and optimize for getting better range + coverage

Who is this guide for? I have tried to make this guide to be a comprehensive collection of the most basic yet essential tips with a set of actions and best practice steps that should be applicable to all types of Zigbee setups, regardless of what type of Zigbee adapter/gateway/hub/bridge/devices that you are using, however, it has been written with a point-of-view in mind of Zigbee solutions that use a Zigbee Coordinator adapter locally via USB dongle/stick or remotely using a serial server ove…

How do I find out, which sensors are not reachable?

Which sensors are not working? If everything is working, the problem may be intermittent and the network is managing it (which is what it’s designed to do). There’s a lot to be said for “If it ain’t broke, don’t fix it…”
