I finally got Chrome on Safari on a Mac to connect.
I downloaded the firmware from here:
https://github.com/pvvx/ATC_MiThermometer
I download a ZIP file from there which contained dozens and dozens of .bin files. I had no idea which to select so I chose the first one:
ATC_v54.bin
I flashed that to the firmware. The log now shows:
So, the custom firmware was flashed. But, now, neither the new sensor or the old sensor work at all:
Old One That Used To Work
No error message. Just no data.
New One
So, both old and new sensors are now bricked and useless.
And once again, a Raspberry Pi project goes horribly wrong.
