Just wanted to add, new honey app have been published few days ago, namely 7.2.0. This is quite big improvement as again it included copy function and old devices inclusion.
I can confirm that I reincluded all the remotes and it works like before. Status updates are again “heared” by the homey and all is working again.
I had quite big problems with this as if homey doesn’t know updated status of kaku device then toggle flows do not work like expected.
So from my perspective give it a go.
