vitotrol2mqtt

Viessmann™ Vitotrol™ device to MQTT

Typically used to send Viessmann™ Vitotrol™ boiler data to a MQTT broker

Installation

go build -v

will generate a vitotrol2mqtt executable.

Usage

Create a YAML file based on vitotrol2mqtt.yml, including your credentials and the attributes you want to send to the MQTT broker.

Registered attributes can be found here: https://gitlab.xpandity.com/eliott/go-vitotrol/blob/master/attributes.go#L82 (field Name).

If you want an attribute that is not registered, use a name like NAME_0xNNNN where NAME is the name of the attribute, and NNNN is the hexadecimal representation of the attribute ID, for example (read only):

FuelConsumption_0x108d

You can use vitotrol + rget all, bget or remote_attrs actions to discover attributes (german language skill needed :) ).

Note that you can provide the special attribute ComputedSetpointTemp. This fake attribute is computed using several others and corresponds to the setpoint temperature (as it appears that this value is not available in Vitotrol™ served attributes).

Once your vitotrol2mqtt.yml is ready, you can launch:

vitotrol2mqtt -config vitotrol2mqtt.yml

Docker

Alternatively, you can run the tool in a docker container.

docker-compose build --no-cache
docker-compose up 

That's all.
