Hello, Is it possible to retrieve messages "as in Vicare" informing us of updates on Viessmann servers from the API? Thanks for your help.

nerixs · ‎28.11.2023

Ich habe das gleiche Problem! Die Stabilisierung der Viessmann Server ist immer noch sehr gut!

Hi @MichaelHanna , Back to the news. The easiest way for maintenance information would be to provide access to: "heating.service.timeBased: activeMonthSinceLastService, serviceIntervalMonths, lastService, serviceDue". Have you been able to discuss this with your team? Cordially

nerixs · ‎27.12.2022

Your users must register a new OAuth 2.0 client Then via: https://documentation.viessmann.com/users/v1 User management must be possible. I don't know how to tell you more.

Hello @Boeb, Machine-to-machine communication with the API? I don't understand what you want to do?

nerixs · ‎09.12.2022

Hi @MichaelHanna, Thank you for this procedure. Better, Eric

Hello, In the example below the responses "equipmentType, errorEventType, errorDescription" are in English. { "eventType": "device-error", "gatewaySerial": "XXXXXXXXXXXXXXXX", "body": { "errorCode": "0f", "deviceId": "0", "modelId": "VScotHO1_200_11", "active": false, "equipmentType": "Boiler", "errorEventType": "Error", "errorDescription": "Service required" }, "createdAt": "2022-09-24T10:04:04.208Z", "eventTimestamp": "2022-09-24T10:03:36.000Z", "editedBy": "system", "origin": "system" }, Vicare gives these answers in the language of the boiler (for me in French). Are these translations accessible from the API?

Hello, The subject is almost six months old, we are very patient.

nerixs · ‎17.10.2022

Hello, I raise the subject with hope!

nerixs · ‎31.05.2022

Hello, No news about this error problem that does not appear?

nerixs · ‎31.05.2022

Hi @MichaelHanna , Back to the news. The easiest way for maintenance information would be to provide access to: "heating.service.timeBased: activeMonthSinceLastService, serviceIntervalMonths, lastService, serviceDue". Have you been able to discuss this with your team? Cordially

Thank you @MichaelHanna , We hope you can bring us a solution! Cordially

Hi @HubertMaier , concerning the error messages, you can check the "Events" endpoint, which is documented here: https://developer.viessmann.com/en/doc/events-mw-iot/v1

nerixs · ‎09.02.2022

Hi @MichaelHanna , The point of termination of events, in my opinion, should be questioned as often as possible, in order to highlight the errors or alerts punctual and temporary. Some event repeats and are automatically resolved. With the old Vicare backup, events had allowed me to identify a problem on the water volume of the heating circuit, when there were large heating demands. Regarding maintenance information, the French regulations, as in many European countries, require annual maintenance. This information is really useful and is not even available under Vicar. Could you work with your teams to see what can be done to make this maintenance information available? Best regards,

Hallo, Mein Gaskessel Vitodens 222-W B2LB 19 kW Bodenheizung, 11% Modul bei 0° Aussentemperatur. Bei Wind ist die Modulation mit viel kürzeren Zyklen schnell auf 35 % gestiegen. Welche Art von Rauchrohr kann ich benutzen, um den Gegenwind zu reduzieren? Ehrlich

nerixs · ‎03.02.2022

Hello @MichaelHanna, In previous exchanges, we asked you how to retrieve maintenance information. You told us that errors and other events could be consulted with the "Events" endpoint, which is documented here: https://developer.viessmann.com/en/doc/events-mw-iot/v1. The problem is that this request consumes an additional call to the API. Regarding maintenance information, could you allow access to the "heating.service.timeBased" feature and more precisely to the values of the "activeMonthSinceLastService, serviceIntervalMonths, lastService, serviceDue" points? Sincerely

nerixs · ‎09.11.2021

@JueBag, Thanks for your help. It helps a lot. Best regards

Hello, The thermal baths not using the API are not simple to translate. So that we can all take advantage of them and include them in our developments, could you help me translate them?

@MichaelHanna, did you test the code? @SorinB, your code is not functional as it is. Where is the "$ autorizationTOKEN" variable? Can you provide "sistem_termic.png"? Best regards

Hello @MichaelHanna, Can you give us an answer regarding the maintenance data? Does the eventType: device_message_service work in this direction? Best regards

nerixs · ‎07.09.2021

https://developer.viessmann.com/en/introduction

nerixs · ‎23.08.2021

Hello @MichaelHanna, Thanks for the example with the events-history endpoint, it works. The downside with Event is that it generates an extra call to APIs. Can we retrieve the maintenance information? "heating.service.timeBased: activeMonthSinceLastService, serviceIntervalMonths, lastService, serviceDue" In France, the legislation requires that the boilers be checked every year (12 months). This information is very useful and allows you to anticipate an appointment, and to find the date of the last interview quickly. If Event does not allow it, adding features is hoped for.

nerixs · ‎19.08.2021

Hi, @MichaelHanna I don't see where I didn't understand how with the "Events" endpoint I could retrieve the information related to : "heating.errors.active: ErrorListChanges" "heating.errors.history: ErrorListChanges" Can you please elaborate or give an example? Sincerely

nerixs · ‎19.08.2021

Hi, @MichaelHanna The feature for power consumption (heating.power.consumption) has changed. To find the correct functionality use (heating.power.consumption.total). Sincerely

nerixs · ‎15.08.2021

Hello, The "heating.power.consumption" feature added on July 15, no longer works since August 10. Can you look at the problem? Sincerely

nerixs · ‎22.07.2021

Hi @joeH68 , Your order is good, I get this: { "data": { "properties": {}, "commands": {}, "components": [ "boiler", "burner", "burners", "circuits", "configuration", "device", "dhw", "operating", "sensors", "solar" ], "apiVersion": 1, "uri": "https://api.viessmann-platform.io/iot/v1/equipment/installations/xxxxxx/gateways/xxxxxxxxxxxxxxx/devices/0/features/heating", "gatewayId": "xxxxxxxxxxxxxxx", "feature": "heating", "timestamp": "2021-07-10T17:30:45.346Z", "isEnabled": true, "isReady": true, "deviceId": "0" } } I can’t tell you any more!
