I noticed in the latest update you added support for AC devices to be imported via HA. It would be great if you could also do this for SmartThings so we can make use of the AC control UI on the NSPanel Pro.
Samsung AC units do not expose themselves over Matter or Zigbee and thus cannot be seen by the NSPanel in any other way. To my knowledge the only AC units on the market use Matter over Thread are Worcester Bosch units with an upgraded wifi add on for each unit. Where as most AC manufacturers have a cloud link into SmartThings for AC control.
Given SmartThings normalises these devices, it would be great if you could allow the import of AC devices from SmartThings into eWeLink in the same way you can import them from HA. A side benefit would be that most popular AC brands could then be Matter bridged from NSPanel into other ecosystems.
Otherwise the AC control tile is pretty useless if you are not running HA and even if you were trying to create a virtual AC device in HA → NSPanel → Matter bridge back to SmartThings. It would be a nightmare setting up SmartThings routines to ensure they stay in sync.
