Zigbee: Multiple endpoints crash due to static endpoint var

[FaBjE]

When adding a second Zigbee endpoint the CPU crashes.
I noticed that the same endpoint ID was displayed while I added both endpoints with separate ID's

After some digging I found that the ZigbeeEP class has the endpoint variable as static.
This is not possible as each instance (aka endpoint) must have a unique endpoint ID.
I removed the static and it started working: FaBjE@f0566d8

Unfortunately this breaks several classes as they rely on the endpoint and others being static. For testing I removed those classes so I could compile: FaBjE@2c98584

I think there is some awareness about this issue, but maybe not the severity when trying to use a second endpoint.

Hi @FaBjE, what version of the esp-arduino core are you using?
I have no issues running multiple endpoints on last Zigbee library commits.
Can you try to use the v3.1.x branch?

Hi @P-R-O-C-H-Y
Thanks for your swift response!

I use the latest release V3.0.7

When using master / V3.1.x branch the issues are gone indeed :)

[P-R-O-C-H-Y]

Its fixed in the 3.1.x, but we did not back port zigbee updates to 3.0.x branch.
We will release the 3.1.0 stable release soon. I am closing this issue as it's solved.
Fix was done in this PR: #10551
