issue while setting negative number value for "konf_niveau_rw"

Hello,

I am new on that forum, and only speak english. I am using Vitoconnect device and the API api.viessmann.io/estrella/rest/v2.0. This works pretty well.

I would like to adjust by https PUT request the parameter "konf_niveau_rw" (datapointId=2875) when outdoor temperature range is changing .

My ideal setting is '-7' on warm winter, and '-4' on cold periods. When the boiler displays '-7', reading this "konf_niveau_rw" with the API, it returns '248' (=-7+255). I can manage this conversion. I guess it refers to sign number issue.

It is not possible to write the "konf_niveau_rw" :

Putting '-7' returns "error": "INTERNAL_SERVER_ERROR",

Putting '248' returns "error": "INTERNAL_SERVER_ERROR",

Thanks to the experts who had provided this marvellous facility!

Hello felinh,

the direct acces is not intended for the Vitoconnect 100. So we can´t give you information about datapoints.

For adjusting the heating curve you must be at the heatingsystem.
