Control Plug S through Cloud API

I have exactly the same problem with Shelly 1

https://shelly....eu.shelly.cloud/device/relay/control/?auth_key=XXXXXXXXXXXX&id=YYYYYYYYY&channel=0&turn=on

The answer is

{"isok":false,"errors":{"wrong_channel":"Could not control this relay channel!"}}

Hello,

i had the same problem some time ago too. The shelly_cloud_api_access.pdf is not really helpful at that point. I don't know if there is a better documentation out there but i was able to solve the problem:

The key point is that you have to make a https POST request and not a GET request to switch the plug. You can easily try it out using wget:

wget -q -O - --post-data "id=xyz&auth_key=abcxyz&channel=0&turn=on" https://shelly-11-eu.shelly.cloud/device/relay/control

If you specify your device id and auth_key, it should work.

I am controlling my Shelly Plug S using the python requests library. If you like to have some examples on that just write me.

Nevetheless a GET request is working also, if you only want to get the status information. So this is what makes it really confusing, that it works for one thing but does not work for the other things.

Hello,

I was having exactly the same problem with a Shelly Plug S:

I was sending a POST to the endpoint:

https://shelly-xx-eu.shelly.cloud/device/relay/control/?auth_key=xxx&id=yyy&channel=0&turn=on

and I was getting back the error "wrong_channel": "Could not control this relay channel!"

The problem is that the webservice method allows the get parameters in the URL (auth_key and id), but the command parameters must go on the POST body.

So to solve the problem, you just need to:

send a POST to the endpoint using the auth_key and id parameters: "https://shelly-xx-eu.shelly.cloud/device/relay/c…_key=xxx&id=yyy"

and send in the body, a TEXT with the parameters: "&channel=0&turn=on".

Or, in alternative, simply send a POST to the endpoint without any parameter and all parameters in the POST BODY - i.e.:

Endpoint: "https://shelly-xx-eu.shelly.cloud/device/relay/control/"

Body: "auth_key=xxx&id=yyy&channel=0&turn=on"

Hope this is useful for others .

Thank you!

Can you send an example or sending https with all the commands in the same url ??
