How to create HTTP request string from irrigation system

[Guest Veggie-Joe]

Hello Forum members,

 

I am a Newbie on Fibaro HC2 / LUA and struggling with my next project:

I have a Hydrawise Irrigation Controller (sister company of Hunter).

This controller is already smart and adjusting the irrigation schedule based on weather data via WUnderground.

My plan is to track the status of each zone in HC2 and switch the pump (wall plug) on and off.

API key is available and the connection is working on browser and in LUA code. 

I can run and stop specific irrigation zones via code but I do not know how to get the datastring into HC2 variables.

 

start relay 485761 / zone 3 for 600 seconds: 

local http = net.HTTPClient()

http:request('https://api.hydrawise.com/api/v1/setzone.php?action=run&api_key=XXXXXX&period_id=999&relay_id=485761&custom=600')

 

stop same relay:

http:request('https://api.hydrawise.com/api/v1/setzone.php?action=stop&api_key=XXXXXXX&relay_id=485761')

 

Both is working and I can see the effect on the Hydrawise controller.

 

code for the statusschedule:

I receive following string in the browser:

The last days I read tons of threads in this forum and finally I could manage the http request and reading the json string.

Also set / get of Global Variables is working.

Hi,

 

I am also a newbie and struggling to get the HC2 to communicate with a device sending HTTP messages to my HC2.

 

All I need is for the HC2 to accept the message and then display it in a virtual device. Any suggestions for references or code? 

 

Thanks

Hi Innervations,

 

I made it in a lua scene as a virtual device supports no https only http.

The string is stored in a global variable and I use the global variable (string) in separate scenes for calculations and as trigger for actions.

Hopefully this will help you.

 

My code: 

--[[
%% properties
%% events
%% globals
--]]

function hydrastatus(result)
    local url = "https://your api"
    local http = net.HTTPClient()
    http:request(
        url,
        {
            options = {
                headers = headers,
                method = "GET",
            },
            success = function(response)
                if (response.status < 200 or response.status >= 300) then
                    print(json.encode(response))
                    print("Wrong status '" .. response.status .. "' in response!")
                else
                    --local data = json.decode(response.data)
                    local data = json.decode(response.data)
                      if result then
                    fibaro:setGlobal("Hydrawise_status", response.data)
                    --result(data.master)
                    --result(data.time)
                    --result(data.relays)
                    --result(data)
                      for k,v in pairs(data) do print(k, v) end
                    --for i,v in pairs(data.relays) do print(i, v) end
                    --for i,v in pairs(data.relays[1]) do print(i, v) end
                    for k,v in pairs(data.relays[1]) do print(k, v) end
                    for k,v in pairs(data.relays[2]) do print(k, v) end
                    for k,v in pairs(data.relays[3]) do print(k, v) end
                    for k,v in pairs(data.relays[4]) do print(k, v) end
                    else
                        print('Warning! No calback function. Your IP is ', data.id)
                    end
                end
            end,
            error = function(response)
                print("Connection error: " .. response)
            end
        }
    )
end -- function

hydrastatus(
    function(relays) 
        print("YESSS!!!", "MY RELAYS ARE: ", relays)
        
    end
    )
