I’m releasing a new version of this which uses the new Custom Tiles: Access to Things and Variables feature.
This means you no longer need to setup the Hubitat Maker API. Just pick from the list of devices you already have in SharpTools! Best yet, the updates all happen in real-time rather than relying on polling like the API approach does.
I don’t have any devices with HTML attributes that are still updating in realtime, so my testing of this was fairly limited, but if everything’s working well with it, I’ll update the main post with a link to this as an option. The original API driven version will remain as well if you prefer that.
