I’m asking out of curiosity as this has no effect on ZHA operation and doesn’t interfere with anything. I’ve noticed that when I look at the Zigbee device list, my SkyConnect is listed as Silicon Labs EZSP one time and another time differently; for example, it’s displayed under the name Zigbee Coordinator or SkyConnect v.1.0. Why is this happening?
I have asked myself too.
Probably a bug so suggest report to → Issues · home-assistant/core · GitHub
Believe I read someone reporting seeing something similar before after they had migrated from one adapter to another adapter and the old adapter still being listed as well → https://www.home-assistant.io/integrations/zha#to-migrate-to-a-new-zigbee-coordinator-radio-inside-zha
Did you maybe migrate from a other/older EZSP based adapter to the SkyConnect?
If so then some might also get the same issue if migrate between other radio type adapters as well.
I did. I guess you’re right.
Again, probably a bug in the ZHA integration, suggest report to → Issues · home-assistant/core · GitHub
That way it the root cause can be found so that it can then hopefully fixed for everyone 
Not sure diagnostic logs from ZHA is enough, it probably is, but might be asked to enable debug logging to provide debug logs, see → https://www.home-assistant.io/integrations/zha#reporting-issues
- Both the Zigbee Device Signature and the Diagnostics information can be found under Settings > Devices & Services. Select the Zigbee Home Automation integration. Then, select Configure > Devices (pick your device). Select Zigbee Device Signature and Download Diagnostics, respectively.
When reporting issues also refer to → Reporting issues - Home Assistant
Thanks. I will report.
