Back in 2015, the forum tags “smartapp” and “device type” were used for code submissions. Same with “communitydevices.” They are no longer necessary because since then the forum has been re-organized and now has separate sections for code.

Questions about smartapps or device types should not use these tags. The tags will be removed if applied by mistake since they make it harder to find things in the archives.
