Hi! It took some time... Maybe you already have found some other solution. Now I have made my app available on GitHub. Feel free to test it. https://github.com/pelleros/se.forint.pelle.viessmann As it is has not yet passed the Homey review process you will have to download the source code and install it with the Homey SDK "homey app install". Let me know if you run into problems.

Hi @Edwin-nl My intension is to make my code available at GitHub for anyone to use and contribute. All help to make the integration better is appreciated. I have a Homey app up and running but it is currently only reading outside temp and hot water temp from the API (see attached). Needs though some optimisation in how the data is requested. I'm currently on vacation but when I'm back home I can try to make it available on GitHub. I will let you know when I have made it available. Best regards, Per

Hello, Thank you @hsch09 for the additional information. It would be helpful if Viessmann could clarify thees device model dependancies. Since these consumption details are accessible in the ViCare app, I was hoping they could also be available through the Basic API tier. It would be immensely helpful for customers to monitor and optimize energy use, contributing to both cost savings and environmental benefits. Could someone from Viessmann clarify the availability of these data points for different models? Thank you for your support! Best regards, Per

Hi, I'm developing an app for Homey to read data and control my Viessmann Vitocal 222-A AWOT-E-AC 221-A16. I have tried to find the answer in the forum but since I don't speak German it is hard to understand all the answers. I'm looking for the possibility to read heating.power.consumption.dhw and heating.power.consumption.heating via the API (using the API at https://api.viessmann.com/iot/v2). I can see the information in my ViCare app so the data is obviously available somewhere. Does anyone know how to get thees datapoints? They are both labeled with 'Basic' in the data points development doc (https://documentation.viessmann.com/static/iot/data-points)? It is not included when calling: https://api.viessmann.com/iot/v2/features/installations/{{installationId}}/gateways/{{gatewaySerial}}/devices/{{deviceId}}/features And I get the 'FEATURE_NOT_FOUND' error when calling: https://api.viessmann.com/iot/v2/features/installations/{{installationId}}/gateways/{{gatewaySerial}}/devices/{{deviceId}}/features/heating.power.consumption.dhw Any help would be very much appreciated! Best regards, Per
