Configuration
To enable this climate platform in your installation, first add the following to your {% term "configuration.yaml" %} file.

Optimistic mode
If a property works in optimistic mode (when the corresponding state topic is not set), Home Assistant will assume that any state changes published to the command topics did work and change the internal state of the entity immediately after publishing to the command topic. If it does not work in optimistic mode, the internal state of the entity is only updated when the requested update is confirmed by the device through the state topic. You can enforce optimistic mode by setting the optimistic option to true. When set, the internal state will always be updated, even when a state topic is defined.
Using templates
For all *_state_topics, a template can be specified that will be used to render the incoming payloads on these topics. Also, a default template that applies to all state topics can be specified as value_template. This can be useful if you received payloads are e.g., in JSON format. Since in JSON, a quoted string (e.g., "foo") is just a string, this can also be used for unquoting.
Say you receive the operation mode "auto" via your mode_state_topic, but the mode is actually called just auto, here's what you could do:
{% raw %}
mqtt:
- climate:
name: Study
modes:
- "off"
- "heat"
- "auto"
mode_command_topic: "study/ac/mode/set"
mode_state_topic: "study/ac/mode/state"
mode_state_template: "{{ value_json }}"
{% endraw %}
This will parse the incoming "auto" as JSON, resulting in auto. Obviously, in this case you could also just set value_template: {% raw %}"{{ value_json }}"{% endraw %}.
Similarly for *_command_topics, a template can be specified to render the outgoing payloads on these topics.
