Button for one-time request of hot water

Karel10 — Wed, 08 Dec 2021 15:25:37 GMT

Helllo,

I have Vitodens 200-W + Vitoconnect 100 and I am unsing Homeassistant to read operating values from sensors.

Actually I am trying to find out how to start on-time request for Hot-water.

For example I have motion sensor a would like to to start on-time request for Hot-water only if someone will come to the home.

I dont know which API structure can I use for this, or is this not avaible in public API ? (only for Vicare)

Vicare can not use for automatiozation 😕

Hello @Karel10,

Thank you for the request. The public API provides a feature to control the One time charge of the domestic hot water (DHW): The Feature is heating.dhw.oneTimeCharge

You can call the status of the feature via "curl -X GET curl -X GET https://api.viessmann.com/iot/v1/equipment/installations/[installationId]/gateways/[gatewaySerial]/devices/[deviceId]/features/heating.dhw.oneTimeCharge"

It also provides the functionality to activate/deactivate the one time charge.

As you are using Home Assistant, I cannot tell you how to integrate this function within adapter/plugin you are using. I recommend checking with the developers of the plugin.

I hope this helps.

Michael
