Replace Philips Hue automation with Home Assistant's

I've been the happy owner of several Philips Hue-connected lights for a few years. Some of them are coloured, some of them regular. In addition, I bought a sensor to go along with the light I installed in my toilets: it turns on automatically when it detects a movement there.

In this post, I want to document how I replaced the proprietary automation with Home Assistant's.

The current Philips Hue automation

I mentioned the light and the sensor in the introduction. To manage both directly or via Google Home, you need an additional component - the Hue Hub. The Hub needs an Ethernet connection, but you can't connect it to Wifi.

The next step is to register the device. Installing the dedicated Philips Hue app on your phone or tablet is the first step. Once installed, you can proceed to register the Hub itself. You must then register the Hub itself.

The process goes the same for the motion sensor. After registering it, you can configure it to turn on the light when it detects motion. Even better, you can set the light's intensity (and colour if it's a coloured bulb) to adapt to the time of the day. Indeed, it's better to have a low-intensity reddish light at night to keep your

Migrating to Home Assistant

We will migrate step-by-step, as I did, to show you how straightforward and manageable it is. The first mandatory step is to add the Philips Hue integration.

Integrating Philips Hue

Go to the left Settings menu, then select the Devices & services item on the screen. The opening window displays four tabs: Integrations, Devices, Entities, and Helpers. The default tab is Integrations: click the Add Integration button at the bottom left corner.

Select Philips > Hue, then configure the IP of the Hue Hub. After Home Assistant has detected the latter, it will display it and all associated devices.

Note that you can add multiple hubs, even though one hub can manage (a bit more than) fifty connected devices. At this point, Home Assistant should display every device added to your Hub.

We can now turn on the lights via Home Assistant's UI.

Binding the light to the sensor

Before binding the light to the sensor in Home Assistant, we must unbind it in the proprietary Hub. Go to the Settings > Accessories menu in the Philips app. Select the motion sensor and click the Configure in another app button. You can ensure it's unbound if the sensor now appears in the previous screen with a Not configured in this app label. Additionally, the slider should be disabled.

. As a reminder, an Automation consists of three components:

1. A when condition, the event that triggers the automation


2. A then clause, what to do when the event happens


3. An optional if condition.

Each component can consist of one or multiple components assembled via boolean logic.

It's time to dive a bit deeper.

You can create an automation via the UI by going to the Settings > Automations & scenes menu. It brings you to a screen with three tabs; Automations is the default. Click on the bottom right Create Automation. The Automation is so standard that it has a dedicated menu item!

It's pretty straightforward to configure it. The Blueprint is already selected. You must choose your motion sensor and the light(s) you want to turn on. The UI lists all available choices for the former. For the latter, you can choose a single light Device or a group in an Area or via a Label. The final parameter is self-describing: "Time to leave the light on after last motion is detected." Click on Save.
