hassResolVbus

A custom component for Home Assistant to add Resol Vbus status from a Resol-compatible device.

What's Available?

The custom component will create a sensor with the specified information as attributes. However, since each device has separate attributes, these need to be specified in the configuration file.

Getting started

Please check the Resol Specification to find your device and corresponding attributes.

To install the component, you will need to copy the four py files to you local configuration folder:

 - .homeassistant
 | - custom_components
 | | - resolvbus
 | | | - __init__.py
 | | | - sensor.py
 | | | - pyvbus
 | | | | - __init__.py
 | | | | - vbuspacket.py

In your configuration.yaml, you will need to add a sensor, and set the corresponding attributes:

sensor:
  - platform: resolvbus
    name: MyResol
    ttyPort: /dev/ttyUSB0
    filterSource: 0x7321
    filterDestination: 0x0010
    filterCommand: 0x0100
    attributes:
      - name: temperature_sensor_1
        offset: 0
        size: 2
        factor: 0.1
        type: temperature
      - name: system_time
        offset: 18
        size: 2
        type: time
      - name: pump_speed_relay_1
        offset: 10
        size: 1

Converting attributes to sensors

Template sensors can be added to your configuration.yaml to display the attributes as sensors.

sensor:
  - platform: template
    sensors:
      myresol_temperature1:
        value_template: '{{ state_attr("sensor.myresol" , "temperature_sensor_1") }}'
        friendly_name: "Temperature 1"
        unit_of_measurement: '°C'
  - platform: template
    sensors:
      myresol1_pump1:
        value_template: '{{ state_attr("sensor.myresol" , "pump_speed_relay_1") }}'
        friendly_name: "Pump 1"
        unit_of_measurement: '%'

Logging

If you are having issues with the component, please enable debug logging in your configuration.yaml, for example:

logger:
  default: warn
  logs:
    custom_components.sensor.resolvbus: debug
