Cannot get JSON Response - [ERROR] Operation canceled

[Prokopis Bor 7]

Hello!

I am trying to communicate with a sonoff mini DYI mode from my HC3. I was able to turn on the switch on the sonoff but I cannot get a response to know if the command was completed successfully. Instead I get the following: [ERROR] Operation canceled

The code that I used in my QA is:

 

function QuickApp:buttonOn()

    local http = net.HTTPClient()

    http:request("http://192.168.0.216:8081/zeroconf/switch", {

        options = { method = 'POST', headers = {Accept = "application/json"}, data = '{"deviceid": "", "data": {"switch": "on"}}', timeout = 3000 },

           success = function(status)

        if status.status ~= 200 and status.status ~= 201 then print("failed"); end

           print(status.data);

            end,

         error = function(err)

           print('[ERROR] ' .. err)

         end

      })

end

 

Could anyone help me with this issue to understand what I am doing wrong? 

Thank you

99% IP address with such port is not accessible for HC3 

[Prokopis Bor 7]

10der Thank you for your answer. The IP is SonOff's IP address in my LAN and the port is the sonoff's default communicate port. The SonOff reacts on my POST command and "turns on" but the response I get is: [ERROR] Operation canceled. 

I believe  that the timeout expires without  the HC3 can read the comfirm respond of the sonoff that the switch is at "On State".

I want to get this switch status confirmation of the SonOff .

@Prokopis Bor

Try increasing the timeout to a larger value (for example 6000ms)

I have already done that. Unfortunately this is not the issue.

Thank you for your QA's ! As I understand you have flashed the sonoff with Tasmota firmware. My sonoff is not flashed with tasmota. I use it in DIY mode with sonoff RESTAPI (it is sonoff Mini). 

[10der 832]

Hmm sonoff now can work without clouds? wow.

[Prokopis Bor 7]

Yes some specific models only!

If I use postman I get the answer:  {"seq":23,"error":0}

How can I read this with HC3?

@Prokopis Bor

If it works for you at least from a PC, give a return message here. See picture.

Yes it works from a PC and also from my Fibaro Quick App. The SonOff change state to On but I want to read the comfirmation answer.

If I use postman I get the answer:  {"seq":23,"error":0}

How can I read this with HC3 QA? 

I want to read the  {"error":0} value so HC3 will know that the command has been executed successfully.

Hello,

I have exactely the same trouble with a Dingz module.

If i make a api request from a scene it works perfectly but from a QA i alwas get the message "Operation canceled".

Post request works from my QA. ist it the same for you?

did you find a solution to your problem?

[Prokopis Bor 7]

I will try to make the request from a scene and I will let you know. From the QA I have the same issue as you. I did not find any solution yet. Thanks!

 yes we have got exactly the same issue. After I saw your answer I created a similar scene and when I ran it I got the "200" status answer and {error:0} too. You have helped me a lot with your answer. I haven't found any solution yet. If you have found a solution please let me know! Thanks a lot!

Hi, no sorry i didn't found anything. I think it is a bug on the HC3.

I will tell you if i find anything.

I don't have a sonoff device but I stumbled upon another service where the POST would give "operation cancelled" in a QA on the HC3 (and I had similar code worked on the HC2). My solution was to add the header

['Connection']='keep-alive'

...and it suddenly started to work. Seemed like the HC3 QA closed the connection too fast for the server to read the payload...(?)

You can give it a try and see if it solves your problem...

Thanks @jgab.

Do you have an example of your request?

i will try that
