me too, it worked very well two days ago, but I encounter this problem today.

Exactly same here, I'm on latest iOS 17.1.1

i have the same issue. have you already found the solution? could it be because it is not possible to enter the correct password format? 111-11-111 instead of 1111-1111?

I resolved the issue by thoroughly erasing the flash, then reprogramming the firmware to the ESP chip and pairing up again. The root cause of this problem lies in the ESP chip, when it pairing up with an iOS device, the chip saves the device’s ID, referred to as 'Client ID'. If you have successfully paired once without a complete flash erase, the ESP chip will detect the same Client ID during the second pairing attempt, then trigger the issue. In short, the solution is to perform a complete flash erase every time before you reprogram the firmware. And it is advisable to delete the device in the Home App before pairing up with your iOS devices.

I also resolved the issue, in my case the problem was in a defective DHT11 sensor, for some reason it was blocking the ESP from finishing setup. First I uploaded a clean example of a temperature sensor and it worked flawlessly. Then I replaced the DHT11 sensor and tested it with a simple sketch to make sure it was giving appropriate numbers. Then combined the code and successfully added esp8266 into the homekit. BUT this piece of sh*t didn't want to work properly anyways, each 1-4h it just loses connection and I had to restart it, which is not what I expected.

After fighting with it for a week I just ended up switching to ESP32 and ESP32-HomeSpan library, which has been working without any problem for a week now.

hey! thanks a lot for your support. i have disconnected all hardware from the pin and erased the flash using the terminal, but still have this issue. when i set following setting do i still need to erase the flash manually?

i am able to see the device in the home app but when i try to connect it it shows following message, which translated means: the device is not compatible
