Without more information, the only thought is did you put access_token= at the end of your request? This error is typically syntax related. If you want to PM me the url I can take a look at it.
Or you can wait for the next release and we will have cloud and local endpoints in the app for you to use.
Yeah that's where I copied the beginning's of the URL from to start with... kinda hokey-pokey of copying a part of a url from a forum post then adding to that a piece from the Maker API screen then having to go back and double check and clean up.
Could be simpler of having the "Example" URL in the Maker API page like it is for the Device Info and Command Send URL
well you're right... the one Patrick linked has the little "TM" in the name Hubitat™_Maker_API where as the one on the Index page does not.... see I told you Patrick was Smooth
FYI /on and /off do not work as documented. I can use setLevel/100 and setLevel/0 but they aren't exactly the same. Can also use examples of setting color values for Hue.
It would be helpful if /devices/all or a /devices/values would provide the current values for all devices.
Of course, I still want a WebSocket or other notification API.
