@bravenel, @SBDOBRESCU changing device type does nothing to influence what tiles are set to display as default. The ONLY WAY is to create your own device type and modify the TILES section,specifically:
main "humidity" details(["humidity", "temperature", "battery", "refresh"])
In the example above, ST’s device type had temperature as “main” and I changed it to humidity. I stopped using my own device types once I found out the old version of the app still had the capability to change the default tile to be displayed.
