Ollama Conversation

The Ollama integration adds a conversation agent powered by Ollama in Home Assistant.

This conversation agent is unable to control your house. The Ollama conversation agent can be used in automations, but not as a sentence trigger. It can only query information that has been provided by Home Assistant. To be able to answer questions about your house, Home Assistant will need to provide Ollama with the details of your house, which include areas, devices and their states.

Installation

To install the Ollama Conversation integration to your Home Assistant instance, use this My button:

Manual Insallation

If the above My button doesn’t work, you can also perform the following steps manually:

General Settings

Settings relating to the integration itself.

Option	Description
API Timeout	The maximum amount of time to wait for a response from the API in seconds

System Prompt

The starting text for the AI language model to generate new text from. This text can include information about your Home Assistant instance, devices, and areas and is written using Home Assistant Templating.

Model Configuration

The language model and additional parameters to fine tune the responses.

Option	Description
Model	The model used to generate response.
Context Size	Sets the size of the context window used to generate the next token.
Maximum Tokens	The maximum number of words or “tokens” that the AI model should generate in its completion of the prompt.
Mirostat Mode	Enable Mirostat sampling for controlling perplexity.
Mirostat ETA	Influences how quickly the algorithm responds to feedback from the generated text. A lower learning rate will result in slower adjustments, while a higher learning rate will make the algorithm more responsive.
Mirostat TAU	Controls the balance between coherence and diversity of the output. A lower value will result in more focused and coherent text.
Temperature	The temperature of the model. A higher value (e.g., 0.95) will lead to more unexpected results, while a lower value (e.g. 0.5) will be more deterministic results.
Repeat Penalty	Sets how strongly to penalize repetitions. A higher value (e.g., 1.5) will penalize repetitions more strongly, while a lower value (e.g., 0.9) will be more lenient.
Top K	Reduces the probability of generating nonsense. A higher value (e.g. 100) will give more diverse answers, while a lower value (e.g. 10) will be more conservative.
Top P	Works together with top-k. A higher value (e.g., 0.95) will lead to more diverse text, while a lower value (e.g., 0.5) will generate more focused and conservative text.
