Aeotec ZW132 Dual nano switch UK


I’m using a Smartthings v3 Hub

I have installed the Aeotec ZW132 Dual nano switch and paired successfully. The two switches appear in my dashboard, but I can only control switch 1 from the app. The second switch shows as “checking status” (see screenshot). When I select switch 2 in the app, it says “unable to connect”

The wall switches work and I see events in live log for both switches when toggled manually, so I know the hub is connected.

Any ideas?

Replying to my own post… Both switches work ok in the old (classic?) smartthings App. I guess I’ll just use that.
