Home Assistant Calorie Tracker

A HACS integration that helps you monitor your daily calorie intake and progress toward your fitness goals. If using an LLM conversation agent (such as OpenAI Conversation), you can log everything through your voice assistant. A custom panel is included for visualizing your progress.

Push for Home Assist Voice Preview Edition

I built this integration after purchasing a Home Assistant Voice Preview Edition. This device (combined with an LLM as a conversation agent) has been a game changer for using a voice assistant without getting frustrated. This thing actually works. Being able to quickly speak to this voice assistant to log calories, exercise, and weights without having to look at my phone makes all the difference. Not to mention the LLM pretty accurately estimates calories if you don't know them. It's awesome.

Features

• Tracks calories, exercise, weight, body fat, and macronutrients.
• Set your starting weight, goal weight, and daily calorie goals.
• Includes a Home Assistant side panel to view/edit all data.
• Numourous custom cards are available to place in any dashboard (see below)
• Supports multiple profiles for different users.
• Configurable week start day (Sunday or Monday) for weekly summaries.
• With an LLM conversation agent you can:
  • Log calories, exercises, daily weight, and body fat with your voice assistant
  • The LLM can also estimate calories and macros from descriptions (better details for better estimates)
  • Log calories and macros by taking a picture of food (LLM must support image inputs)
  • Ask the LLM how many calories you have remaining for the day.
  • Ask the LLM for your current macros.
• Service calls are available to log food, exercise, weight, body fat, and to fetch data.
• Calculates estimated weekly weight loss/gain.

Log Calories/Body Fat by Taking a Photo (LLM required)

• Logging calories and body fat percent via photos is supported via an AI Task service from one of these integrations(NOTE AI Task is required as well as a model that accepts image inputs is required):
  • Anthropic
  • Azure AI Tasks
  • Google Generative AI Conversation
  • Ollama
  • OpenAI Conversation

Macronutrient Tracking

• Track protein, carbohydrates, fat, and alcohol intake alongside calories.
• View macro percentages in the daily log and dedicated macro cards.
• Visual gauge cards for each macronutrient with customizable min/max targets.
• Pie chart visualization showing macro distribution as percentage of total calories.
• Automatic calculation of calories from macros (4 cal/g protein & carbs, 9 cal/g fat, 7 cal/g alcohol).

Calorie Goal Types

The integration supports multiple goal types to fit different approaches to calorie management:

• Fixed Intake: Set a specific daily calorie intake target (e.g., 2000 calories per day)
• Fixed Net Calories: Set a target for net calories after accounting for exercise (food-exercise)
• Fixed Deficit: Set a specific daily calorie deficit below your maintenance calories (e.g., 500 calories below calculated baseline calorie burn + calories burned from workouts)
• Fixed Surplus: Set a specific daily calorie surplus above your maintenance calories (e.g., 500 calories above calculated baseline calorie burn + calories burned from workouts)
• Lose Percent Body Fat per Week: Calculates a net calorie daily goal to lose a specific weekly body fat percentage per week (0.5-1.0% recommended)
• Gain Percent Body Fat Per Week: Calculates a net calorie daily goal to gain a specific weekly body fat percentage per week (0.25-0.5% recommended)

Auto logging Peloton workouts

• The Calorie Tracker integration will detect if there is a Home Assistant Peloton Sensor profile and allow you to link the Peloton profile to a Calorie Tracker profile. Peloton workouts will then be auto logged.

Dashboard Cards

In addition to the built-in side panel, you can add Calorie Tracker cards to any Home Assistant dashboard.

Setup Dashboard Cards

1. Add the frontend resource :

• Go to Settings > Dashboards > Menu (3 dots) > Resources

iOS/Android widgets

You can create a widget on your phone home screen that opens directly to the food analyzer screen or the chat assistant.

iOS

In iOS, use the Shortcuts app and create a shortcut that uses the Open URLs action. Create 2 Open URLs actions. Set the URL for the first action to be 'homeassistant://navigate'. This will make sure the companion app is open, which seems to be required to access the embedded photo popup screens. For the second Open URLs action, paste the appropriate homeassistant:// URL using the examples below.

Android

In Android, from the Home Assistant Companion App settings, create a shortcut of 'dashboard' type and use the appropriate 'homeassistant://' URL using the examples below (use whatever label, icon, and description you choose). Once the shortcut has been created, you can move the shortcut to the homescreen.

• Base format (open the panel and request a modal[pop-up]):

  homeassistant://navigate/calorie_tracker?modal=<modal_name>

• Options for <modal_name>:

  • food_camera — open the food photo analysis flow
  • bodyfat_camera — open the body-fat photo analysis flow
  • chat — open the Calorie Tracker chat assistant

• If the user has more than one Home Assistant server configured in their mobile app, append &server=<server_name_or_id> to target a specific server. Example:

  homeassistant://navigate/calorie_tracker?modal=food_camera&server=home

• You can also target a specific profile by including profile=<spoken_name> query parameter (optional):

  homeassistant://navigate/calorie_tracker?modal=food_camera&profile=Jason
