WebCoRE works in the new app but there are a couple of areas to be aware of.
- webCoRE can not manage and/or use the STHM state directly in the new app as it did with SHM in the Classic. You will need to use virtual devices as a workaround or use automations/scenes to manage STHM.
- there is a known display bug when you go to select available devices to webCoRE. Basically you are presented with the cancel button are selecting devices but it still saves them.
