They may be doing that, but it appears they were simply doing more and better editing on some data fields for createEvent, sendEvent, and possibly other commands. The main downside is they did not tell this to anyone, nor did they bother to throw an error when bad data was found, it’s much easier to simply ignore the command. Idiots!
My system is now functioning as it was before this all began. However, that’s only until I complete porting a few more devices, mainly keypads, to Hubitat.
