I have a few suggestions. If you’re committed to viewing it on ST dashboard in the app perhaps you could create a virtual temperature device that mirrors the temperature of the door sensor and favorite that.
Or solutions like action tiles, webcore, sharp tools, and others offer custom ‘dashboards’ that are much faster than the ST app itself. Here is an android widget of sharp tools that shows the temp of a contact sensor.
If you don’t care about knowing the open/close status at all, you can switch the device type in the IDE to “SmartSense Temp/Humidity Sensor”. If you still want to use it as a contact sensor, you can create a modified device handler using the instructions given here (ignore that this is for an Iris sensor; both sensors use the same SmartSense device handler):
