Hello,
I'm not quite sure to understand what you want. Since version 1.0.1 all feature exposed by viessmann are exposed(in read and write). You'll find every method implemented on the api documentation here:
https://htmlpreview.github.io/?https://raw.githubusercontent.com/thetrueavatar/Viessmann-Api/develop/docs/class-Viessmann.API.ViessmannAPI.html

Is it possible to implement it in your API?

from viessmann-api.

Hello,

i have found a way to start the OneTimeCharge.
You only need to enable it with the "setRawJsonData" function as follows:

<?php
include __DIR__ . '/bootstrap.php';
$mode = "{\"mode\": \"activate\"}";

$viessmannApi->setRawJsonData("heating.dhw.oneTimeCharge", "activate", $mode);

And this code to deactivate:

<?php
include __DIR__ . '/bootstrap.php';
$mode = "{\"mode\": \"deactivate\"}";

$viessmannApi->setRawJsonData("heating.dhw.oneTimeCharge", "deactivate", $mode);

Best regards

Now i have it tested. The OneTimeCharge is starting on my heatingsystem, but i get this message in the browser:

Message: Return value of Viessmann\API\ViessmannAPI::startOneTimeDhwCharge() must be of the type string, null returned Code: 0

Here my code:

<?php
include __DIR__.'/bootstrap.php';
$viessmannApi->startOneTimeDhwCharge();

echo "OneTimeCharge is: ".$viessmannApi->isOneTimeDhwCharge();

The same message, when I'm stopping the OneTimeCharge:

Message: Return value of Viessmann\API\ViessmannAPI::stopOneTimeDhwCharge() must be of the type string, null returned Code: 0

Here are details from my heating:
Viessmann Vitodens 300-W B3HB
Viessmann Vitocell 100-W

from viessmann-api.

I think the code in ViessmannAPI should be:

public function isOneTimeDhwCharge(): bool
    {
        return $this->getEntity(ViessmannFeature::HEATING_DHW_ONETIMECHARGE)->getProperty("active")["value"];
    }

    public function startOneTimeDhwCharge()
    {
        $data = "{\"mode\": \"activate\"}";
        return $this->setRawJsonData(ViessmannFeature::HEATING_DHW_ONETIMECHARGE, "activate", $data);
    }

    public function stopOneTimeDhwCharge()
    {

        $data = "{\"mode\": \"deactivate\"}";
        return $this->setRawJsonData(ViessmannFeature::HEATING_DHW_ONETIMECHARGE, "deactivate", $data);
    }

But its not tested

Thank you for your great work. Now it works fine.
I took some changes in the example/StartOneTimeCharge.php

Here is my file to start:

<?php
include __DIR__.'/bootstrap.php';
$viessmannApi->startOneTimeDhwCharge();
sleep(1);
echo (int)$viessmannApi->isOneTimeDhwCharge();

I have add the sleep(1); for waiting a short time, so that the OneTimeCharge at my heating can start. After that waiting I get a response from API that the OneTimeCharge runs or not.

Is the startOneTimeDhwCharge() working reliable? I'm not sure what the correct call is. In StartOneTimeCharge.php you call the startOneTimeDhwCharge() twice, whereas @rogrun calls it once, but has a delay of 1s before getting the status? Thanks.

from viessmann-api.

Hello, it is not nessesary to call it twice. In my use case, I call startOneTimeDhwCharge () once and wait a second to query whether it ran successfully.

I start OneTimeCharge in one PHP and query the status in another. This means that the methods are not executed via the cache.

Best regards

from viessmann-api.

Hello. I could also make startOneTimeDhwCharge() working now, but the script always returns 0. Even if I have a delay of 5s, it returns 0.

StartOneTimeCharge.php:

<?php
include __DIR__.'/bootstrap.php';
$viessmannApi->startOneTimeDhwCharge();
sleep(5);
echo (int)$viessmannApi->isOneTimeDhwCharge();

Once I call another script right after startOneTimeDhwCharge() to only get the status of isOneTimeDhwCharge() it is working.
Is there some kind of caching?

StatusOneTimeCharge.php

<?php
include __DIR__.'/bootstrap.php';
echo (int)$viessmannApi->isOneTimeDhwCharge();

from viessmann-api.

Hello, you have to call the request in each single php, because since the API is limited from Viessmann-Server last year, all requests in this API are cached. So this Code will failed:

include DIR.'/bootstrap.php';
$viessmannApi->startOneTimeDhwCharge();
sleep(5);
echo (int)$viessmannApi->isOneTimeDhwCharge();
