Xiaomi mi led desk lamp 1s error integration

ESPHome
1

I flashed the lamp for work and automation in HA. But after rebooting the firmware, an error began to appear in the log for this lamp:
[D][esp-idf:000]: E (1322577) system_api: Base MAC address from BLK3 of EFUSE version error, version = 87
I didn’t find a solution to this problem, or I didn’t quite understand what to do.
Maybe there is someone who has encountered this error and successfully solved it? Or does someone know how to fix it?

The extra line was the solution for the same kind of error for the Xiaomi bedside lamp.

Wow, I just noticed that it’s now possible to control the lamp.
Thank you!

But for general information, what could cause this error?

There are some recent changes in ESPHome that turn out to be breaking changes for the type of ESP32 that is used in these devices.
