Temperature reverting to C

Same issue here with Samsung water sensors. Change to F and reverts back to C.

And now I’ve joined your ranks. All of my sensors that report temperature separately from humidity are showing C. Note to self: don’t play around with settings.

I’ve submitted a support request - #1016861

Mine show F on the tiles and C when I open them.
Simple Device Viewer shows them in F.

Same with mine. I also have some custom dth temperature things and I know its passing F with the temperature updates but still see C when I open the sensor to the details page

Same here!

Me too. Ecobee sensor, so impacts the cloud integrations, too.

I think it’s a problem in the UI, not tied to any single DTH. Behavior is consistent across all of my devices, just different depending on whether the slider is temperature only or a combo temp/humidity slider.

If support tells you to uninstall/reinstall the app, don’t bother. I went ahead and bit the bullet on that one. It shows F the first time you look at a device after reinstalling, but then starts showing C every time after.

I just noticed that many sensors and a couple other devices I have that report temperature have started using the C scale instead of F, which is what my Location’s scale is set to be. Anyone else experiencing this?

This just started happening, but I don’t know exactly when. I know I should email support, but as it always happens with emailing support, I don’t want to wait a few days only to be told to reinstall the app, remove and rejoin a device, and/or eventually reset my hub…

What’s odd is that the DTH the device is using doesn’t matter, and on the main tile in the new app’s dashboard the scale is correct. It’s only when looking at the detail view of the device that you see the wrong scale. The Classic app uses the correct scale, of course.

Here’s an example of a sensor using ST’s stock SmartSense Open/Closed Sensor DTH:

Wonderful new app:

Experiencing the same issue.

Experiencing the same issue as well on the iOS app.

Same issue here as well…

Same issue for me. Nothing I do changes it permanently.

Take a video / screenshot and report it to support@smartthings.com

Just found in my inbox that Support had responded to my ticket on Friday. Advice so far is just to set Temperature Scale to F in the IDE.

So… I’ll second @RBoy in saying that everyone should submit a ticket to draw attention to this.

This is an issue with the device plugin that was released last week. As noted, the plugin is not honoring the location setting of Fahrenheit and changing the device to Fahrenheit via the gear icon does not persist.

The issue was escalated to the appropriate development team.


@Brad_ST, happening on Android too!


Happening on my android.
