I read here recently that a native Shelly driver is close upon us. Anyone have any idea how close?
Nope...
Oh... hmm... ok.... 
Move to HE stymied by all these shelly devices scattered throughout the house. 
Not quite yet...
There is a community driver for Shelly devices... HERE
Yes, but his repo is not responding. I also understand that his code was abused and sgrayban doesn't allow access anymore. I think I properly requested it but no response.
I do allow access but I restrict how long access is given now.
