What does materialNumber refer to in https://developer.viessmann.com/en/doc/service-documents/v3 ?

In my quest to get more information about E0 error I was trying to use this service-documents/v3 call. But I am missing an important parameter it looks like, what is materialNumber refering to?

Could some examples be shared please.

Thanks in advance

Jørgen

Hi @jborup ,

the key "materialNumber" identifies the product you are looking for. The materialNumber is equal to the first 7 digits of your boiler serial number.

You can identify your boiler serial number with the endpoint https://api.viessmann.com/iot/v1/equipment/installations?includeGateways=true and searching for "boilerSerial".

Best,

Michael
