MQTT HVAC component - not subscribing to broker?

[DirkieP]

Running HASS v 0.55.1 (on Ubuntu 16.04)
Running paho-mqtt v 1.3.0

I am having the following configuration.yaml section:
`climate:

• platform: mqtt
  name: Downstairs
  modes:
  • day
  • eco
  • night
  • off
    mode_command_topic: /hass/thermo/1/setmode
    temperature_state_topic: /hass/thermo/1/setpoint
    current_temperature_topic: /hass/thermo/1/measured
    temperature_command_topic: /hass/thermo/1/settemp
    mode_state_topic: /hass/thermo/1/mode
    swing_modes:
    fan_modes:
    initial: 20`

This configuration does not return any configuration errors (so don't worry about the formatting) and properly displays the component. So far, so good...
Testing proper behaviour of the mqtt topics works fine too: example, when publishing an mqtt topic to '/hass/thermo/1/setmode day', the HVAC system switches to "Day"-mode and returns it's confirmed status to '/hass/thermo/1/mode' (payload is then 'day').

Problem: However Home Assistant does not record any state changes, while it is supposed to be subscribed to '/hass/thermo/1/mode' to collect mode_state_topic. I do not see any instance of it in the logs.
The same counts for '/hass/thermo/1/settemp' that is used for making changes to the temp setting, that results in a change of '/hass/thermo/1/setpoint', which should be picked-up by HASS to adjust the target temperature setting ('temperature_state_topic').
The only topic the MQTT HVAC component seems to be subscribing to is 'current_temperature_topic' which is reflected correctly in the interface.

Other findings: When starting up HASS, the logs return a number of errors which only appeared when setting up the HVAC MQTT component (so they dissappear when the component is removed from the configuration.yaml). So, the error must be related somehow to the component... The following is the error which appears once during the startup:

Hope this helps... Dirkie

This should be fixed with #9802

Works! Thanks great!
