So, I’ve tested all for me know variants of the firmware and all have the same problem:
zigbee2mqtt 1.17.0
zigbee-herdsman 0.13.46
| Revision | cold reboot | reboot | reboot + wait | z2m restart | comment | |||
|---|---|---|---|---|---|---|---|---|
| revierline | 20200327 | no | no | no | yes | without SBL | ||
| jethome | 20201010 | no | no | no | yes | with SBL | ||
| modkam | 20200211 | no | no | no | yes | with SBL |
“yes” means you did not have to re-pair respectively to “anounce” the device again. Often a complete re-pair is not needed.
I find it rather confusing that obviously nobody ever made that observation. Is it confirmed that this also happens with the USB variants of the CC2538?
