Support for shelly plug 2?

[dominch]

hello, I could not run this app with shelly plug 2, it seems to be bigger, maybe more advanced option.

App seems to connect with some messages, others give 500 :(

BTW: readme link to shelly site is not valid now

Hi,

since I don't have this device I cannot reproduce the problem. Could you be more specific which calls fail?

Maybe I can figure out the issue looking at the API docs.

device is configured as 192.168.201.45 from logs:

seems that /rpc/ returns 404 but, there is some response on /status link:

I did some initial investigation, and it looks like the Shelly Plug 2 is a Gen 1 device, while the Shelly Plug S is a Gen 2 device. It looks like Gen 1 devices dont support RPC calls, but only simple HTTP requests.

The backend currently proxies the RPC calls, which isnt very elegant. Do support other devices such as Gen 1 devices, a larger refactor will be required sadly, to support both RPC and HTTP calls.

As stated in the other issue, im currently studying for exams, but i hope to get back to this afterwards.

Edit: i have added a note to the readme stating currently supported devices to prevent confusion in the future.
