After revert fw back to original stock fw at https://devbis.github.io/telink-zigbee/ I got an empty HW Revision string. I tried atc1441 and pvvx online flashers and usb-uart with restore original fw 130 -they all restoring fw but HW Revision still empty. MI Home not accepting such device with verification -29 error.

Fixed by erase flash via usb-uart then load 130 fw. Mihome successfully paired. Please note MAC has been changed now and HW Rev = 0000. Then at https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html load ATC 4.7 fw and HW changed now to B1.7. The real HW is 2.0 on PCB
