I'd like to propose that, immediately following the 2.2.5 release, Hubitat have a "Day of Documentation" (or, even better, Documentation Week) to fix and supplement the online documentation. The idea is to have a short period of concerted effort by Hubitat and interested developers to fix, complete, and supplement the Developer documentation. For a product that depends on a developer community, complete documentation is a huge step in supporting developer efforts (and reducing the time that staff spends answering question!).
There are many pages that have gone missing (State object, Command Object, Mode Object, others?), and huge "to be done later" sections that just haven't gotten done. These could all be fixed.
I realize the documentation concept is supposed to be one where developers can contribute to the documentation via the wiki. But users / developers are often not in a position to do that (I can't properly contribute to what I don't fully understand). In any case, the moderation process for user contributions appears to be stalled -- months ago, I spent time editing the Capabilities page (adding "unit" information, adding a section on "Implementation notes", etc.), but it never got incorporated and the edits now seem to have disappeared from my pending edits without any response from a moderator. I'd be willing to give another try at this as part of a concerted effort to fix the full set of documents.
If Hubitat shows interest, I'd volunteer to contribute to at least the Capabilities page by adding information on the proper "Units" to include in SendEvent messages and to the "State Object" page -- I recently learned a lot from the staff about how this object works and particular race conditions that need to be considered when writing to the state. It would be helpful to have a set of "Implementation Notes and Cautions" on these pages to centralize relevant knowledge that is now sprawled about the forums.
