HTTP Get request with header authentication

[Pilaarbijter]

Hello everyone,

In short I have this WIFI-heater from Adax that I would like to command to change the temperature via theLocal API
(link)

Snippet of most important information on the above mentioned site:



I am trying to get a HTTP get request done via Loxone but I don't seem to get it working. I added printscreens of what I have in Loxone thus far. I probably need the Unix time
from Loxone but I can't wrap my head around how to import it into my request.


















I programmed the same request in a Python script and everything is going flawlessly. (code below)

This leads me to believe that there probably is a problem with the concept unix time that is required to run the command.

I'm planning on making a full HowTo about this adventure, so any help here would be great for the community aswel


Working Python-code
-------------------------

#! /usr/bin/bash python3

# controls heater

# install dependencies with: pip install bleak requests

import http.client

import urllib

import time

import requests

import urllib3


HEATER_IP = '192.xxxxxxx # replace with your heater IP from the prepare_demo

HEATER_TOKEN = 'xxxxxxx' # replace with your secure password from the prepare_demo

def get_status():

url = 'https://' + HEATER_IP + '/api'

payload = { 'command': 'stat', 'time': int(time.time()) }

headers = { 'Authorization': 'Basic ' + HEATER_TOKEN }

response = requests.get(url, params = payload, headers = headers, timeout = 15, verify = False)

response_json = response.json()

target_temperature = response_json["targTemp"]

current_temperature = response_json["currTemp"]

print('Current temperature %d, target temperature: %d \n' % (current_temperature, target_temperature))

urllib3.disable_warnings() # heater uses self signed certificate

get_status()


exec(open('PushoverDown.py').read())

Replace <v1> with <v>. Only <v> is accepted in a Virtual Output.

If <v> is used, the expectation is that the Unix Timestamp would be at the entry to the Virtual Output. Use as Digital Output should be unchecked. The Unix Timestamp is available in the Time functions -



But this would also mean a command is sent on every change (every second).

You really need a Status Block with a trigger to allow the Timestamp through only when desired. This also sends a 0 on Off. This may be an issue without testing.

Thanks for the reply!


Sadly the adaptations to this set-up don't seem to work.







I was able to verify the following command via Postman without any issues (it increase the desired temperature to 14 degrees celcius):


https://192.xxx.x.xxx/api?command=set_target&value=1400&time={{$timestam p}}


This leads me to believe that there is a problem in Loxone with the Unix Timestamp not being transported into the URL properly.

EDIT:

I also considered your remark regarding the zero/off value being a potential problem. Although it might be responsible for an overload of commands towards the heater, it does not explain the problem of the temperature not changing (since a request sent is a request sent (I think).

[Tico]

I'm more inclined to think it may be a problem with the 'HTTP header for On'. Just change your token to something false and send a screenshot of exactly how the line looks.

edit:
And what does the Postman header look like?

The other issue may be the 'https'. Are you on a Miniserver Gen1 or Gen2?

[Pilaarbijter]

Could you specify on 'how the line looks' that you would like to see? I'm not really sure what you mean by that. A diagnostic report of sorts?

Set-up in Postman:




Token is set up: Basic xxxTOKENxxxx

I reckon my server is Gen 2. It was installed in 2019 and is limegreen.

[Pilaarbijter]

Nevermind, I'm such an idiot. I forgot to add the "Authorization:" to my header for on in Loxone. Unbelievable.

Thanks for the help though, it's much appreciated

I thought this looked a bit short....

Did you get adax to work? If yes. How did you request the token? Did you use the program block?
