Remember conversation stopped working in 2025.3

Describe the bug
A clear and concise description of what the bug is.

I recently updated to home assistant 2025.3 but I was having similar issues before updating. I was on 2025.2.4 and it would only remember a few past messages and then throw an “unable to communicate with the api” error.

Now I’m not getting any past messages remembered. I’ll say “tell me a joke” and then say “another” and it will say “sorry I’m not sure what you’re referring to” when in the past it would tell me another joke.

Expected behavior
A clear and concise description of what you expected to happen.

I expected it to remember past interactions up to 5 messages like before but even setting it to 2 does not work at all.

Logs

I've run into this issue as well, and upon doing a little digging, it looks like Home Assistant have updated how they manage conversations somewhat... with Home Assistant itself now being able to handle conversation histories.

The notable change that breaks this plugins history though is that Home Assistant itself now handles generating conversation IDs, however this plugin generates a new conversation ID itself if the provided one does not exist in the plugins own internal conversation history.

I was able to get this working again by simply disabling the generation of new conversation IDs within the plugin itself, and only ever use the one provided by Home Assistant.

I did this by editing \config\custom_components\llama_conversation\conversation.py on my HomeAssistant instance, changing this block:

https://github.com/acon96/home-llm/blob/develop/custom_components/llama_conversation/conversation.py#L358-L363

    if user_input.conversation_id in self.history:
        conversation_id = user_input.conversation_id
        conversation = self.history[conversation_id] if remember_conversation else [self.history[conversation_id][0]]
    else:
        conversation_id = ulid.ulid()
        conversation = []

to:

    conversation_id = user_input.conversation_id
    if user_input.conversation_id in self.history:
        conversation = self.history[conversation_id] if remember_conversation else [self.history[conversation_id][0]]
    else:
        conversation = []

Just to be clear: this is not a complete fix in that it does not update the plugin properly to support the new means of HA handling chat history etc. This simply gets the plugins own internal chat history working again (which, frankly, is good enough for me until the maintainer has the time to attend to this properly)
