Hi,
I started to develop a binding for Shelly products. I have a Shelly1 and a Shelly2. These will be implemented and tested for the time being, the rest of the product family I will implement as well as possible, but can not test. Is there any interest in having the binding published in due course?
I’m only doing it because I wanted to work on programming bindings and I’m not really a fan of MQTT 
You can just contact me and let me know if someone is interested or not.
