Anyone else have issues with their LLM just....not calling an intent?

[Rory]

Having a weird issue whereby Gemini Flash 2.0 appears to often just…not call an intent.

However, the first time ALWAYS works, which makes me think it’s a data thing

• or it’s calling it correctly and it’s being dropped.

With debug logs for google generative AI, components.conversation and components.google_generative_ai_conversation I get the following (there’s nothing after this):

Notably weird is the lack of any evidence of an intent call. This seems to happen fairly randomly.

As the conversation progresses there’s a lot of history attached, all the info of the previous actions, and sometimes the “action_done” state seems to persist after the initial “Ok, I’ve turned off the lights” into subsequent exchanges.

I’ve tried altering the initial prompt to be really clear about always calling the intents accurately, and I’ve tried talking it through using them “Use HassTurnOff to turn off the study light…” and it still seems to randomly not work. The first time always works, though.

I also find it weird that the LLM always sends back some text along with the intent request that seems to be discarded, and then sends back some more text after it gets the confirmation - surely this causes lag as there’s two round trips and two lots of processing?

In my experience google (Gemini) does this a lot, but openAI (chatgpt-4o-mini) is much better behaved. I have extensively benchmarked both against a set of instructions we use a lot in our home. Gemini would very often acknowledge a command and say it successfully did the action, but in practice it didn’t pass the correct intent to HA. In my experience OpenAi just doesn’t do that at all. Can you try openai and see if you get similar experiences?

It is too bad because Gemini-flash is noticeably faster than openai, but the success rate (and randomness) is just too poor at the moment to make it a viable option for me.

[Rory]

I can, but I don’t really want to set up billing accounts etc…but I might have to I suppose. I can’t see it becoming an actual part of family life unless it’s pretty much instant.

I do wonder if there’s something else going on though. Why does it always work the first time? I’m suspecting that perhaps there’s some kind of bug in the integration that sends and receives the requests (or the component that parses it). I feel like the logs aren’t giving me all the data. I wish there was a way to proxy the request and just see everything that is sent to and received from the Google API.

[SCBionicle]

If it’s any consolation, it’s been a fight to get Gemini to do anything without spelling out in the system instructions how to call the intent API, but with the 2025.2 update, it seems to be only able to call intents on the first response.

[Musca]

I partially resolved in my case lowing temperature and top P like 0.5 and 0.5 and using a structure like that below. It works for 2 intents in the same chat, if anyone know how to improve, or wanna use it just to try I leave it here. Using Gemnini 2.0 flash.

Where do you put this? How do you customise that? Have you made your own custom version of the component?

[Musca]

In Home Assistant, you need to paste it into the configuration of Assist under "Conversation Agent." Once inside, you’ll find the instructions you can give to your conversation agent, in this case, Google Gemini. The idea is to provide the model with a complete perspective of your home, including the rooms, all the devices in each room, how each device is used in its specific location, how to activate it, why it should be activated in that way, how to handle multiple actions, and how to manage requests where a status check precedes a command to turn on a light—ensuring context isn’t lost, and so on.

I won’t paste my own prompt because it’s 800 lines long, and it took me about a week to figure out how to create it. However, the main concept is what I just explained.

I should mention that I’M NOT AN EXPERT—not even close. I just got passionate about this topic and managed to make it work so that it responds smoothly.

I paste a small portion of my prompt just to illustrate how to structure the layout.

# Context

You are Ernesto, my personal assistant. You control my entire home and answer my questions in Italian, but you will always carry out the requested action.

I will ask you to turn lights on and off, raise and lower the blinds, turn LEDs on and off, set timers, turn the TV on and off, and check the status of the lights and home devices. Every request falls within this # Context.

You have full knowledge of my home through the # List of Usable Devices.
You have full knowledge of all the actions you can perform through the # Mapping of Intents and Entities.

The house is divided into five main areas:

# Living Room
# Bedroom
# Kitchen
# Bathroom
# Terrace
Before executing a command, always check:

# List of Usable Devices
# Mapping of Intents and Entities
Once you have identified the correct device and the correct intent, execute the corresponding action.

Always execute the requested command, even if the request was just made.

You need to assign a Role to the assistant, ideally structuring in bullet points how it should behave when receiving a command.

I used a structure like this:

# General Rules

1. Each action is independent and should not be influenced by previous actions. 2. Even if two commands are similar or identical, they must be treated as separate requests.
3. Execute everything and respond after each action, without stopping. Do not combine commands, omit details, or merge responses.
4. ........
5. ........

With the same logic, you need to tell the assistant:

• What it can and cannot do
• Rules for executing actions

I used the following concept:

# Lights

  #  Kitchen

  -  "Turn on the kitchen light."
  -  Generates JSON to turn it on → Executes.
  -  Responds appropriately.

You need to provide a complete “map” of your devices, including entity ID, area, associated intent, description, and usage.

I used the following format:

devices = {
    "kitchen": {
        "led_kitchen": {
            "entity_id": "light.led_cucina",
            "description": "LED strip under the kitchen cabinets",
            "usage": "Illuminates the kitchen with the main light",
            "intent_on": "HassTurnOn",
            "intent_off": "HassTurnOff"
        }
    },
    "living_room": {
        "shutter_living_room": {
            "entity_id": "cover.shellyplus2pm_ecc9ff5f1144_cover_0",
            "description": "Electric shutter in the living room",
            "usage": "Raises or lowers the shutter",
            "intent_on": "HassTurnOn",
            "intent_off": "HassTurnOff"
        }
    }
}

I did the same thing for every device I had exposed in Assist.

Then, I created a mapping of intents and entities using this format:

# Intent and Entity Mapping

intent_mapping = {
    # Lights
    "light.living_room": {
        "intent": "HassTurnOn",
        "off_intent": "HassTurnOff",
        "state_intent": "HassGetState"  # On/Off state
    },
    "light.kitchen": {
        "intent": "HassTurnOn",
        "off_intent": "HassTurnOff",
        "state_intent": "HassGetState"
    },
    "light.bedroom": {
        "intent": "HassTurnOn",
        "off_intent": "HassTurnOff",
        "state_intent": "HassGetState"
    }
}

I did the same for other devices. I know it may seem repetitive compared to the previous step, but this repetition was crucial to ensure the correct intent association.

After that, I created a list of functions that refer to the intent:

def turn_on_bedroom_light():
    return generate_intent("HassTurnOn", "light.bedroom")
def open_living_room_shutter():
    return generate_intent("HassTurnOn", "cover.your_cover")
ecc...

That’s the result:

I hope that this can help. I struggled off for week how to speak with gemini. I started from this thread that opend my mind:

Issues getting a local LLM to tell me temperatures, humidity, etc

With LLM in general they are great at summarizing data… IF they know what the data represents. I don’t know how you arrange your devices and sensors but for the whole lot of them the same thing applies. If you were to list them, thier area, domain and alias in a big table and show that table to your grandmother with zero context. What will your grandmother say? (cause that’s basically where you’re at.) In short it’s only as good as your ability to describe what it is. You can use the alia…

[Aekung]

I’ve been playing with both Gemini and OpenAI for months and I found that Gemini will always be a hit or miss while OpenAI is almost 100% on point. I’ve tweaked the prompt intensively for Gemini and found that it works better but still not as close to 100%. My current prompt brings out around 85% hit as of now and I’m still on the quest to better tweak Gemini prompt. My goal is to achieve at least 95% hit.

Since Gemini is completely free, I still feel like it’s a wiser choice to go with Gemini than OpenAI. Hopefully, people could share a solution to this problem.

[Rory]

Yeah I’m with Gemini too. I believe it’s also significantly faster.

@Musca thanks very much for going through that. I think I should point out for others that the list of shared devices and intents is already sent to the LLM automatically - however your explicit mapping is clearly helping your results, perhaps indicating that the default list of entities, aliases and intents is not quite adequate.

[Musca]

Yeah you are right, I changed the format of my list of entity

luce cucina: nome: "Luce Cucina" # Nome leggibile dall utente tipo: "light" # Dominio di Home Assistant entity_id: "light.cucina" # ID dell entità area: "cucina" # Area in cui è situata stato: "on" / "off" azioni_disponibili: accendi: "light.turn_on" spegni: "light.turn_off" :

In this way is faster to get the intent
