With my current workload and the fact that ST will be killing off groovy apps. I’ve decided to focus completely on the Hubitat version.
Seeing as your posting on a Hubitat forum I will assume you have a Hubitat hub. So if there are certain devices keeping you tethered to ST then I recommend running ES on Hubitat and using the third party hub connect between ST and HE.
I’ve asked my former Nest Manager collaborator to give ES a once over and he’s helped me optimize the code for v4. The few simple tweaks have drastically improved performance on HE eliminating the need for a lite mode.
Unfortunately it won’t run on ST due to restrictions in the JVM.
The initial release of v4 won’t be packed with a bunch of new features, those will likely come with v4.1.
I have some big ideas that will open up ES to be the ultimate Alexa integration.
