[VitoConnect] Viessmann VitoConnect Binding

[STSC]

Hello,

are there any plans for a VitoConnect Binding using openHAB3?

At the moment I’m only aware of the external API of @thetrueavatar using PHP/CURL.

[VitoConnect] Getting readings from Viessmann Heating system via VitoConnect

Viessmann company has written to all(?) users of their API. **From the coming week on, a threshold will become active that prevents from unauthorized use of the API** **.** This will affect all third-party solutions, which can thereby no longer be used. We are aware that the demand for APIs to our technologies for integration into other solutions and third-party systems is increasing. To provide you with an opportunity for this, we will launch a portal in the next two months for all devel…

Is this still the way to go?

As of me, no plans, at least until Viessmann is moving towards an official API. However they only posted intentions and a rate limiter on the unofficial API until now.
The scripts as posted are working in OH3.

I have tested thetrueavatar’s API. Some are working, some not.

Working:

php GetHotWaterStorageTemperature.php
56.6
php GetBoilerTemperature.php
31

Not working:

php GetActiveProgram.php
Message: Call to a member function getProperty() on null
Code: 0
php GetActiveMode.php
Message: Call to a member function getProperty() on null
Code: 0

Can you confirm this or do I make something wrong?

Never worked with those “not” working routines. Have you tried the “getActiveModeErrorHandling” rountine instead of getActiveProgram"? Putting in a circuitID should be a possibility.

Thanks for the hint. Changed the circuitId in the bootstrap.php from 0 to 1. Now it is working.
