@twlawrenceko , your issue may be similar to #4 , and the solution can be found here: #4 (comment).

Basically, please search for the below config option in your sdkconfig file and change it from y to n.

CONFIG_NEWLIB_NANO_FORMAT=y

Let me know if it fixes the issue for you.

Once I click any button of the esp-light under the Home app, the esp8266 reboots itself, is this normal?

Here is the serial monitor:

@twlawrenceko , the lightbulb example was primarily built for ESP32-Wrover-Kit and the driver part may not work as is on ESP8266, because of difference in the timer/ledc modules. You may have to refer the ledc example under ESP8266-RTOS-SDK and change the lightbulb.c file accordingly.
