How to interpret Developer Z-Wave Node columns?

z-wave

#1

My goal is to make the Z-Wave mesh as responsive and stable as possible. To be able to do so, I need to see what is going on and how all nodes are connected. That is done through the page:
https://developer.athom.com/tools/zwave

However, can someone explain the column Tx Error and Rx and why my NodOn wall plugs have received (Rx) something 2.352.719 times and still counting upwards 2-3 times each second? What are they doing? It is both NodOn plugs that is behaving like that. Also sometimes they don’t respond when using the wall switch or the app so I guess something is wrong with Homey that is spamming these nodes?

What does it actually mean if I spot a node that for instance have 12% Tx Errors? What can I do to make the node run perfectly? All 4 nodes in the screenshot with Tx Errors are between 3 to 5 meters away from Homey in the same room.

Also, what can I actually do with the popup menu with the 4 choices as in the screenshot above? What does Heal do and when should I use it? If anyone can take the time to explain these for a new user, it would be great. Thanks!

Rx = receive signals.
So homey received that amount of signals from your device, looking at your other devices there is definitely something wrong with your plugs and this happend in a short amount of time, try enabling the log below to see what they send.
If it is COMMAND_CLASS_METER then it is a known issue of the (micro) plugs themselves and you should contact nodon about this, as it is a manufacturing error.
I’ve seen the same with 1 of my micro plugs I have (I have 7 in total).

Tx = transmit signals (send toward the device),
60 times something was send, with 7 (12%) where it was not received by the device (homey knows this by not receiving the “ok I received your command” back, also known as noAck (no acknowledgement))

Heal:
every mains powered device has a table inside with which devices are nearby (routing purposes).
With heal you let that device know to renew that table.

Send basic on/off, send the most basic on/off signal there is in zwave, every device that can turn off or on should react to this (unless secure, then it depends on what the manufacturer implemented)

Send test frame, sends homey’s NIF (node information frame) to the device, 99% of the time it does nothing, so not useful unless you dive deep into zwave to know what it does.

Thank you very much for your help, Caseda! Your information was most helpful. The log shows the same error as you mentioned so I’ve contacted NodOn to fix it.

I guess it shouldn’t be any Tx Errors at all in a healthy Z-Wave mesh network or is the errors like in my screenshot to be expected?

The TX errors probably are there because of the amount of traffic the 2 plugs generate.

A factory reset of the NodOn Plugs helped. So far.
