Cannot get installationId, gatewaySerial and deviceId

MrAnderson — Thu, 04 Nov 2021 09:07:18 GMT

Hi,

at https://developer.viessmann.com/en/doc/iot/overview it is said that a simple GET request to https://api.viessmann.com/iot/v1/equipment/installations should return the installationId.

Everything I get is

{"data":[],"cursor":{"next":""}}

To query the API endpoint I'm using the small PHP script from https://www.viessmann-community.com/t5/Getting-started-programming-with/To-help-get-started/td-p/181347 which shows me my user details.

I simply added the following at the end of the PHP script:

$url = "https://api.viessmann.com/iot/v1/equipment/installations/"; $curloptions = array( CURLOPT_URL => $url, CURLOPT_HTTPHEADER => $header, CURLOPT_SSL_VERIFYPEER => false, CURLOPT_RETURNTRANSFER => true, //CURLOPT_HTTPAUTH => CURLAUTH_BASIC, ); // Data Curl Call // $curl = curl_init(); curl_setopt_array($curl, $curloptions); $response = curl_exec($curl); curl_close($curl); echo($response);

Am I missing something?

Cheers

Andreas

Hi @MrAnderson ,

This topic is related to the issue you stated in this thread right? https://www.viessmann-community.com/t5/Getting-started-programming-with/Some-code-to-receive-info-from-the-Viessmann-boiler-v0-2/m-p/195577/emcs_t/S2h8ZW1haWx8Ym9hcmRfc3Vic2NyaXB0aW9ufEtWUVNJUjZBRkJIMEdFfDE5NTU3N3xTVUJTQ1JJUFRJT05TfGhL#M117

Solution was that the account you are using has no installation registered.

Best,

Michael

Hi, I get the same error message. But I do not use ViCare (Vitovalor 300p), only Vitodata300 and Vitotrol. Is there anyting else required to register my installation for data retrieval via the API?!

Thanks in advance.

@snigge for using the API for your device, your system must be connected through a Vitoconnect or using the connectivity inside the device (if available) and be registered using the ViCare app. Vitodata is unfortunately not compatible with the API.

Regards,

Michael

Hello,

I used this address to get installationId, gatewaySerial and deviceId:

https://api.viessmann.com/iot/v1/equipment/installations?includeGateways=true

What I get is JSON type data, such as installationId and gatewaySerial but there is no deviceId. 😞

Any advice?

Thank you.

I'm also having problems with the deviceId.

This is working:

https://api.viessmann.com/iot/v1/equipment/installations/{{installationID}}/gateways/{{gatewaySerial}}/devices

The deviceID result is like

id "gateway" or ""RoomControl-1" or "HeatDemandControl"

but these deviceIDs don'T work with https://api.viessmann.com/iot/v2/features/installations/{{installationId}}/gateways/{{gatewaySerial}}/devices/{{deviceId}}/features

viErrorId "req-e76ed613ba894480bca7cf2fe47a1a4d"
statusCode 502
errorType "EVEREST_ERROR"

Please help, thanks.

I think you are making the same error as me.

You can't just put this addrss in your browser. It won't work.

You need to use something like POSTMAN.

I have to learn it myself too.
