Zigbee TX and RX stats

Questions & Help

Homey firmware v12.13.0/v13.0.0 added some communication statistics for Zigbee devices as part of the Homey Developer Tools. For each Zigbee device it includes the number of commands/messages sent by:

  • Homey to the device (TX);
  • Homey to the device that errored out/were not delivered (TX Error);
  • The device to Homey (RX).

What is not clear to me: do the TX counts only include commands meant for that specific device? Or does the count also include the messages meant for other devices but routed via that device?

My guess would be that these statistics are not based on what devices report (I don’t think there’s such a thing in Zigbee), but that Homey maintains counters on where it sent messages to, and how many it received. Which would mean that TX will only count the messages meant for a specific device, because AFAIK Homey doesn’t know through which other devices messages will be routed.
