I had to rebuild my entire SmartThings smart home settings…everything due to an update wiping out all my devices. I’ve managed to re-install all but my Samsung Family Hub refrigerator but that is a different thread.
My problem is now my weather and thermostat are in Celsius and I want Fahrenheit. Yes my Honeywell T6 Pro is set to Fahrenheit and that is what it displays. How do you change this? I’ve looked everywhere and there is no place to change it in the app…
I replied to your other post in a different thread
Sign in at my.smartthings.com
Find the “manage locations“ option. On an iPad, it’s on the three vertical dot menu at the top right, but it may be somewhere else on a different device.
You will then be able to change the temperature scale.
Found it…Thank You!..the system thinks I live in Canada and not the US.
This sounds like it should work, but it currently doesn’t. Looking at the developer console, it says
GeneralError: Rejected HTTP Response
I found an older thread. The instructions there worked! Note that the URL there now redirects to my.smartthings.com/advanced/locations, which is much nicer. 
Switch the remote control to “Engineering mode” (remove 1 battery, hold both Temp buttons while putting the battery back) so you can put the codes in.
In the menu set "on d1 auto ", and “on 05 cool”.
All the rest menus leave as they are “** 00 **”.
Put the code in with 5 clicks on the Power button, and activate the code with another set of 5 clicks on the Power button.
Remove the batteries, and put them back to restart the remote.
Enjoy Celcius instead of F on your Samsung indoor unit.
Cheers.
Thank you…
