I realize that the problem is somewhat widespread via this thread: Zigbee2mqtt : Error SYS - Ping after 6000ms au démarrage - #161 par guim31
I have the same issue and I don’t see any solution…
I’m using the memory card and a Sonoff. No power issues.
So I don’t know what to do… If you have any ideas?
I tried this: Zigbee2mqtt : Error SYS - Ping after 6000ms au démarrage - #127 par Tlse-vins
But it doesn’t change anything at all
