Howto

I followed this youtube howto from a year or so back. It is mostly correct.

Summary - configuring the devices

--Turn the units on (do this one at a time if you have multiple)
--Go to the TELink Flasher page https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html. I suggest doing this on your phone as it needs to be a device with bluetooth.
--Use the tool to connect to the device, and grab the Mi Keys. Note them down. You won't need them if flashing the custom ATC firmware, but keep for future if needed.
--Flash the latest custom firmware (it is already loaded in the web page)
--Check the website here: if you want to know what the settings do (eg you can change to Fahrenheit, remove the little comfort smiley face, and extend the battery life with less reporting)
--For Advertising type, choose "MIJIA (Mi Home)". Previous notes (including the howto youtube video) said "Mi" or "Mi Like", but this works for me.
--Take note of the new name of the device, it will be something like ATC_91E1BB (which is the end of the MAC address)
