No Zigbee reset after upgrading to v5.
If I understood correctly, this means that I must (re-)add all my Zigbee devices and repair all the (Zigbee) Flows. To do this, I must plan a holiday.
So, this is only realistic for me, if more than 30% does not work anymore.
“Have you run the Zigbee health check script 4?” Not yet, planning to do in the near future.
