Hilo

Hilo integration for Home Assistant

⚠️ Breaking change (v2024.2.2 and lower unusable)

Hilo's login has stopped using "Resource Owner Password Flow" and started using "Authorization Code Flow with PKCE". The old login method has been permanently closed on april 10th, 2024.

Introduction

This is the unofficial HACS Hilo integration for Home Assistant. Hilo is a smart home platform developed by a Hydro Quebec subsidiary. This integration has no direct tie with Hilo or Hydro Quebec. This is a community initiative. Please don't contact Hilo or Hydro-Quebec with issues with this Home Assistant integration, you can open an issue in the GitHub repository instead.

If you want to help with the development of this integration, you can always submit a feedback form from the Hilo application and requesting that they open their API publicly and that they provide a testing environment to the developers.

Shout out

Big shout out to Francis Poisson who's the original author of this integration. Without the work he put into this integration, I would probably have never even considered Hilo.

Another big shout out to @ic-dev21 for his implication at multiple levels.

I decided to move the integration here because of the latest updates from Hilo broke the original one, and I took the time to completely rewrite it. Hilo is now pushing device readings via websocket from SignalR.

Features

• Support for switches and dimmers as light devices
• Get current and set target temperature of thermostat
• Get energy usage of pretty much each device
• Generates energy meters and sensors
• Sensor for Hilo Events (challenges)
• Sensor for Hilo Gateway
• Now configuration is done via the UI
• Updates are now closer to realtime
• NEW: Authentication directly on Hilo's website
• NEW: Outdoor weather sensor with changing icon like in the Hilo App

To Do:

• Add functionalities for other devices
• unit and functional tests
• Adding type hints to the code
• Now available here
• Map send energy meters automatically to energy dashboard

Installation

Step 0: Compatible install

This custom component requires that Hilo has carried out the installation in your home. It will not be possible to set it up otherwise.

This custom component has been tested to work by various users on HA OS (as bare metal or VM), Docker with the official (ghcr.io) image and Podman. Other types of install may cause permission issues during the creation of a few files by the custom component.

Step 1: Download files

Option 1: Via HACS

Make sure you have HACS installed. Under HACS, click the '+ EXPLORE & DOWNLOAD REPOSITORIES' button on the bottom of the page, search for "Hilo", choose it, and click download in HACS.

Option 2: Manual

Download and copy the custom_components/hilo directory from the latest release to your custom_components directory in HA.

Step 2: Add integration to HA (<--- this is a step that a lot of people forget)

In HA, go to Settings > Devices & Services > Integrations. In the bottom right corner, click the '+ ADD INTEGRATION' button.

If the component is properly installed, you should be able to find the 'Hilo integration' in the list. You might need to clear your browser cache for the integration to show up.

Configuration (new install)

The configuration is done in the UI. When you add the integration, you will be redirected to Hilo's website login page to authenticate.

You must then accept to link your account. To do so, you must enter your Home Assistant instance's URL or IP address and click Link Account.

After this, you will be prompted to assign a room for each one of your devices.

Configuration (update from a version earlier than v2024.3.1)

After update, you will get an error saying you must reauthenticate for the integration to work.

After correctly linking your account like in the previous section, you should see a popup telling you the reauthentification was successful.

Energy meters

Energy meters are a feature of this integration. We used to manually generate them with template sensors and automation, but they now have been fully integrated into the Hilo integration.

Warning

When enabling Hilo generated energy meters, it's recommended to remove the manually generated ones to have the most accurate statistics, otherwise we might end up with duplicated data.

If you're facing an issue, and you want to collaborate, please enable debug log level for this integration and provide a copy of the home-assistant.log file. Details on how to enable debug are below.

Procedure

If you want to enable the automatic generation of the energy sensors, follow these steps:

• Make sure that the utility_meter platform is loaded in your configuration.yaml file from home assistant. You simply need to add a line like this in your configuration.yaml:

  utility_meter:
  

• ClickConfigure on the integration UI and check the Generate energy meters box.

• Restart home assistant and wait 5 minutes until you see the sensor.hilo_energy_total_low entity getting created and populated with data:

  • The status should be in collecting
  • The state should be a number higher than 0.

• All generated entities and sensors will be prefixed or suffixed with hilo_energy_ or hilo_rate_.

• If you see the following error in your logs, this is a bug in Home Assistant, and it's because the power meter in question has 0 W/h usage so far. This will disappear once usage has been calculated.

  2021-11-29 22:03:46 ERROR (MainThread) [homeassistant] Error doing job: Task exception was never retrieved
  Traceback (most recent call last):
  [...]
  ValueError: could not convert string to float: 'None'
  

Once created, energy meters will then have to be added manually to the energy dashboard.

Other configurations

Other options are available under the Configure button in Home Assistant:

• Generate energy meters: Checkbox

  Automatically generate energy meters, see procedure above for proper setup Requires this line to be added to your configuration.yaml file:

  utility_meter:
  

• Generate only total meters for each devices: Checkbox

  Calculate only energy total without splitting between low cost and high cost

• Also log request data and websocket messages (requires debug log level on both the integration and pyhilo): Checkbox

  Allows higher logging level for developers/debugging

• Lock climate entities during Hilo challenges, preventing any changes when a challenge is in progress.

  Prevents modifying temperature setpoints during Hilo Challenges

• Track unknown power sources in a separate energy sensor. This is a round approximation calculated when we get a reading from the Smart Energy Meter.: Checkbox

  All energy sources other than Hilo hardware are lumped into a single sensor. Uses the reading from the home's smart meter.

• hq_plan_name: String

  Define the Hydro Quebec rate plan name. Only 2 values are supported at this time:

  • rate d
  • flex d

• appreciation phase: Integer (hours)

  Add an appreciation phase of X hours before the preheat phase.

• pre_cold phase: Integer (hours)

  Add a cooldown phase of X hours to reduce temperatures before the appreciation phase

• Scan interval (min: 60s): Integer

  Number of seconds between each device update. Defaults to 60 and, it's not recommended to go below 30 as it might result in a suspension from Hilo. Since 2023.11.1 the minimum has changed from 15s to 60s.

     pyhilo: debug

If you have any kind of python/home-assistant experience and want to contribute to the code, feel free to submit a pull request.

Prepare a dev environment in MacOS / Linux

1. Prepare necessary directories:

$ HASS_DEV=~/hass-dev/
$ HASS_RELEASE=2023.12.3
$ mkdir -p ${HASS_DEV}/config
$ cd $HASS_DEV
$ git clone https://github.com/dvd-dev/hilo.git
$ git clone https://github.com/dvd-dev/python-hilo.git
$ git clone https://github.com/home-assistant/core.git
$ git --git-dir core/ checkout $HASS_RELEASE

NOTE: We also clone home-assistant's core to make it easier to add logging at that level repo.

2. Launch the container:

$ docker run -d -p 8123:8123 \
  --name hass \
  -v ${HASS_DEV}/config:/config \
  -v ${HASS_DEV}/python-hilo/pyhilo:/usr/local/lib/python3.11/site-packages/pyhilo:ro \
  -v ${HASS_DEV}/hilo/custom_components/hilo/:/config/custom_components/hilo:ro \
  -v ${HASS_DEV}/core/homeassistant:/usr/src/homeassistant/homeassistant:ro \
  homeassistant/home-assistant:$HASS_RELEASE

3. Check the container is running

$ docker ps
CONTAINER ID   IMAGE                                    COMMAND   CREATED       STATUS          PORTS                    NAMES
bace2264ee54   homeassistant/home-assistant:2023.12.3   "/init"   3 hours ago   Up 28 minutes   0.0.0.0:8123->8123/tcp   hass

4. Check home-assistant logs

$ less ${HASS_DEV}/config/home-assistant.log
$ grep hilo ${HASS_DEV}/config/home-assistant.log

5. Activate debug logs

$ cat << EOF >> ${HASS_DEV}/config/configuration.yaml
logger:
  default: info
  logs:
     custom_components.hilo: debug
     pyhilo: debug
EOF
$ docker restart hass

Before submitting a Pull Request

It goes without saying you must test your modifications on your local install for problems. You may modify the .py files inside the following folder. Don't forget a backup!

custom_components/hilo

If you need to modify python-hilo for your tests, you can pull your own fork into Home Assistant with the following on the CLI:

pip install -e git+https://github.com/YOUR_FORK_HERE/python-hilo.git#egg=python-hilo

You must then restart Home Assistant for your install to take effect. To go back to the original, simply type:

pip install python-hilo

And restart Home Assistant

Submitting a Pull Request

• First you need to fork the repository into your own userspace.
• And then, you can clone it on your computer.
• To maintain some kind of tidiness and standard in the code, we have some linters and validators that need to be executed via pre-commit hooks:

pre-commit install --install-hooks

• You can now proceed with whatever code change you want.
• Once you're done with the code change, you can stage the files for a commit:

git add path/to/file

• And you can create a commit:

git commit -m "I changed this because blabla"

• Finally, you can push the change in your upstream repository:

git push

• At this point, if you visit the upstream repository, GitHub should prompt you to create a Pull Request (aka PR). Just follow the instructions.
