Hello everyone. I'm new here and my name is Philip.
I have a script to scrape the data from my solar inverters website but how can i send the scraped data to different dummy devices?
Please help. I'm stuck. Thank you

If you have the various values already in your python program, then you could use JSON calls to get data into the domoticz database for chosen devices.

If your website shows the data as in your second screen print, you could also use http poller setup in the hardware section to get the data in.

Hoe geraak ik aan de json url? Is dit via een script in python?

How do I get the json url? Is this via a script in python?

Here you have a python script that does something like this for an Omnik Inverter.

Thanks but that's not what I'm looking for. I just want an addition to my script to send the result to domoticz and I also have no idea how to get a json url.

Thake a look at this example script https://www.domoticz.com/wiki/Python_-_ ... o_PVOutput

Here is an extract from one of my python programs. It shows you how to assign a json url string to a variable and then how to call that url.

The string created from the combination of two substrings called "baseJSON" and "apiCall" is called with requests.get.

Code: Select all

import requests, json

## Domoticz server
domoticzIP="127.0.0.1"   # internal IP address of the Domoticz server. 
domoticzPort="8080"      # Domoticz port
baseJSON="http://"+domoticzIP+":"+domoticzPort+"/json.htm?"   # the base string for any JSON call.

def getPercentageDevice(varIDX):
    # function to get the value of a percentage device indicated by the varIDX number
    try:
        apiCall="type=devices&rid="+str(varIDX)
        response = requests.get(baseJSON+apiCall)
        responseResult=str(response.json()["status"])
        if responseResult=="ERR":
            raise Exception
        else:
            varString=response.json()["result"][0]["Data"]
            varValue=float(varString.split("%")[0])
            responseResult=True
    except:
        print("ERROR: unable to retrieve the value of device with IDX ",varIDX)
        print("Response was : ",response.json())
        responseResult=False
        varValue=None
    return responseResult,varValue

and a similar construct you can then use to update a device. Here is an example for a text device:

Code: Select all

def setTextDevice(textIDX,displayText):
    # update the value of a text device and adds an entry to the device log file
    try:
        if len(displayText)<=200:
            urlText=urllib.parse.quote(displayText)
            apiCall="type=command&param=udevice&idx="+str(textIDX)+"&nvalue=0&svalue="+urlText
            response=requests.get(baseJSON+apiCall)
            responseResult=str(response.json()["status"])
            if responseResult=="ERR":
                raise Exception
            else:
                responseResult=True
        else:
            print("ERROR: displayText too long (max 200 characters).")
            raise Exception
    except:
        print("ERROR: failed to update text device with IDX ",textIDX)
        print("Response was : ",response.json())
        responseResult=False
    return responseResult
