Homekit pairing failed

[yuhengqiu]

Hi guys, when I tried to pair to HomeKit, I got "Coundn't add Accessory" error and failed. Actually it was stucked at:

POST /pair-add Not implemented!
10.0.0.71 -- [01/Aug/2020 17:27:31] code 404, message Not Found

If I implements pair-add in hap.py, then it added pair, but got stucked at:

Exception happened during processing of request from ('10.0.0.71', 51700)
Traceback (most recent call last):

Anyone has succeed in pairing to HomeKit? Did I miss something? Cheers
