Shelly is a manufacturer of excelent devices like roller, switch, lamp, etc.
it has european recognition and growing fast.
a lot of persons are buying this for its great quality and acessible price
this week they have launched their open API for 3rd party apps
it would be great to launch oficial support to it !
I have more than 30 devices atm, and would really like to see that.
For operating shellies in local network (not cloud connected) you can used nice custom component: https://github.com/StyraHem/ShellyForHASS
What you refer is just a new cloud api access, so it should be another component for this I think 
Well here I have been using Shelly devices for a while and just flashed them with ESPHome (they are most mainly based on ESP) and so they show up as “native” devices in HA
