ZHA Network Freezing Up - MAX_MESSAGE_LIMIT_REACHED

Configuration Zigbee

Could you give us more details about your system? Coordinator, number of routers, number of end devices etc? Presumably you follow all the standard advice about having the stick on the end of a USB cable, powered hub and so on.

You might also look at your channel usage (from download diagnostics on the ZHA integration page). It ought to look something like this:

    "energy_scan": {
      "11": 52.75969252664325,
      "12": 84.164247274957,
      "13": 85.82097888710312,
      "14": 55.9836862725909,

Do you make much use of Zigbee groups? They can sometimes flood the network if they are overused - though probably not at 5am…

If the max message error is coming from Zigbee I’m not sure switching to Z2M will make much difference - the network will be the same whichever integration you use.

Lots of good advice here:
