As above…ive tried rebuilding from scratch on a few occassions… and then randomly Zigbee2MQTT disconnects with this error…

The coordinator is a poe SLB device. Which is in its current status alive and online.
Ill set up the HA from scratch…configure ZHA on a Sonoff, add in the SLB connection - everything will work fine for a few weeks, then itll go offline.

HA is a VM running on ProxMox with a fixed IP.

What device do you exactly have ?

3

Its an SLZB-06P7 - i got the highest specced one i could…i will also add ive got a second one running as a router…ive got a 4 storey house so i wanted better coverage.

4

And what firmware versions ?

5

All up to date…in that ive been carrying out the firmware updates according to the HA letting me know theres a new version out…

6

That points to a network disconnection, but if everything is up to date. Have you enabled the watchdog in the add-on ?

7

Yes - watchdog is running, i can also log into the SLB and see that its live and connected to the internet. Im at work at the moment but i can login to home and reboot the poe network switch which will force a reboot of the SLB’s…

This one too ?

10

Edit - error is still there, but now the setting is in its rolling round each time…but thats still a handy setting though! :slight_smile:
