Refresh don't work from some 'things' on dashboard

I have made a dashboard for our phones to get fast overview over temperatures.

Some of the devices (things) are not updating/refreshing the temperatures.

Like this one has very old temperature reading:

How do I get the values to update?

If the device was just recently added to a dashboard, there may not have been a temperature event reported yet.

You can go through the authorization flow to force a device sync to get fresh values for all the devices (User Page ‚Üí Manage Connections). Or you could manually warm up the device to force a temperature change to make sure the event updates are coming through.
