browser_mod

A Home Assistant integration to turn your browser into a controllable entity - and also an audio player and a security camera (WIP).

Example uses

• Make the camera feed from your front door pop up on the tablet in your kitchen when someone rings the doorbell.
• Have a message pop up on every screen in the house when it's bedtime.
• Make the browser on your workstation switch to a specific tab when the kitchen light is on after midnight
• Play a TTS message on your work computer when the traffic sensor tells you it's time to go home.
• Display a full screen clock on your screen if no one's touched it for five minutes

For more usage examples, see the cookbook.

Installation instructions

• Copy the contents of custom_components/browser_mod/ to <your config dir>/custom_components/browser_mod/.

• Add the following to your configuration.yaml:

browser_mod:

• Restart Home Assistant

Note: If you want to use browser_mod with Home Assistant Cast, you need to also add:

resources:
  - url: /browser_mod.js
    type: module

to your ui_lovelace.yaml. Don't worry about where to put browser_mod.js, the integration will handle that automatically, and please note that it's not /local/browser_mod.js.

Usage

Here's a fantastic video summary of all browser_mod functions by Pinkywafer: Youtube link.

Devices

The most important concept of browser_mod is the device.

A device is a machine-browser combination identified by a unique deviceID. The deviceID is randomly generated and may look like ded3b4dc-abedd098.

• Chrome on your desktop and Chrome on your laptop are two different devices.
• Chrome on your laptop and Safari on your laptop are two different devices.
• Two tabs in Firefox on the same computer is one device.
• Two windows in Edge on the same computer is one device.

In the two latter cases, the last loaded tab/window will be the active one.

Note: Incognito mode will generate a new deviceID and thus a new device every time it's started.

Aliases

Since the deviceID can be a bit hard to remember for devices you use often, you can specify an alias in configuration.yaml

browser_mod:
  devices:
    99980b13-dabc9563:
      name: arrakis
    d2fc860c-16379d23:
      name: dashboard

This binds the aliases arrakis to 99980b13-dabc9563 and dashboard to d2fc860c-16379d23.

Note: Aliases must be unique.

Changing deviceID

You can change the deviceID of your device by adding a browser-player card to your lovelace interface and clicking the deviceID at the bottom of the card. Set it to clear to generate a new random one.

You can also set a deviceID by adding ?deviceID=mydeviceID to the end of the URL you're using to access Home Assistant. Be careful - I have no idea what could happen if several devices were to have the same ID. Use ?deviceID=clear to generate a new random one.

Take care to avoid deviceID collissions. There's no telling what could happen if more devices share the same ID.

Prefix

You can add a custom prefix to all entity ids in configuration.yaml:

E.g. to give entities default names like media_player.browser_99980b13_dabc9563 add:

browser_mod:
  prefix: "browser_"

This does not apply to devices with an alias.

Disabling entities

browser_mod creates a number of entities, which is explained below. In some cases, you may not want to do that. If so, add a list of entity types you do not want to add to a disable section, either for each device, or globally to ignore for all unknown devices:

E.g. to disable the light and media_player for the device aliased to arrakis, AND disable all entities for all devices which don't have an alias:

browser_mod:
  devices:
    99980b13-dabc9563:
      name: arrakis
      disable:
        - light
        - media_player
  disable:
    - all

Entities

Once browser_mod is installed, loading up your Home Assistant frontend on a new device will create three to five new devices.

• sensor.<device>
• media_player.<device>
• light.<device>
• If you've enabled it: camera.<device>
• If you're using Fully Kiosk Browser: binary_sensor.<device>

<device> here will be the deviceID of the device but with the dash (-) replaced by an underscore (_). If you've defined an alias, it will be that instead.

E.g:
Connecting your phone with deviceID: ded3b4dc-abedd098 will create the entities sensor.ded3b4dc_abedd098, media_player.ded3b4dc_abedd098 and light.ded3b4dc_abedd098.
Connecting with the computer named Arrakis above with deviceID: 99980b13-dabc9563 will create the entities sensor.arrakis, media_player.arrakis and light.arrakis.

sensor

The sensor will display the number of connected views (tabs/windows) of the device. Note that using multiple view isn't really recommended, and any action targeting a device will happen in the last loaded view.

The sensor also has the following attributes:

attribute	content
type	browser_mod
last_seen	The time when the device was last seen
deviceID	The deviceID of the device.
path	The currently displayed path on the device.
visibility	Whether the frontend is currently visible on the device.
userAgent	The User Agent of the associated browser.
currentUser	The user currently logged in on the device.
fullyKiosk	True if the device is a Fully Kiosk browser. Undefined otherwise.
width	The current width of the browser window in pixels.
height	The current height of the browser window in pixels.
battery_level	The current battery level of your device - if supported
charging	The current charging state of your device - if supported

media_player

The media_player can be used to play sounds on the device.

NOTE: Because Apple is Apple; on iOS you need to touch the screen once after loading the frontend before any playback will work.

light

The light can be used to blackout the screen. For Fully Kiosk Browser, the screen will actually turn off. For other browsers, the interface will just be covered with black (the screen is still on, will have a visible glow in the dark, and you won't save any battery).

camera

For security and UX reasons, the camera must be enabled manually on a device by device basis.

Enabling the camera is done by adding camera: true to the devices configuration in configuration.yaml:

browser_mod:
  devices:
    99980b13-dabc9563:
      name: arrakis
      camera: true
    d2fc860c-16379d23:
      name: dashboard

After restarting Home Assistant (and clearing cache), the next time you load your interface your browser will ask you if you want Home Assistant to be able to access your camera. Some browsers (e.g. mobile Safari) will ask every time you make a hard refresh.

Be aware that keeping the camera on may make your device run hot and drain your battery.

The camera does not work well with Fully Kiosk Browser. If you're using FKB, use the built-in camera functionality instead. It's better in every way.

binary_sensor

The binary_sensor will only be available for Fully Kiosk Browser PRO devices. It's state will be the state of the camera motion detector of the device (5 second cooldown).

Services

browser_mod registers a number of services.

All service calls have one parameter in common; deviceID which is a list of devices to execute the comand on. If deviceID is omitted, the command will be executed on all currently connected devices. deviceID may also contain aliases.

You can also activate any service from the frontend by using the fire-dom-event tap_action.

- debug

service: browser_mod.debug

Display a popup with the deviceID and a javascript alert with the deviceID on all connected devices.

- set_theme

service: browser_mod.set_theme
data:
  theme: clear_light

will set the current theme to clear_light on all devices.

- navigate

service: browser_mod.navigate
data:
  navigation_path: /lovelace/1
  deviceID:
    - ded3b4dc-abedd098

will open your second lovelace view on just the device ded3b4dc-abedd098.

Note: navigation_path does not have to be a lovelace path. All paths in Home Assistant works. (E.g. /states, /dev-info, /map)

- more_info

service: browser_mod.more_info
data:
  entity_id: camera.front_door
  deviceID:
    - ded3b4dc-abedd098
    - dashboard

will show the more-info dialog of camera.front_door on the devices ded3b4dc-abedd098 and dashboard.

The optional parameter large: true will make the popup wider.

- toast

service: browser_mod.toast
data:
  message: Short message

Display a toast notification on all devices. The optional parameter duration: determines the time (in ms) that the toast is shown. Set to 0 for persistent display. Default is 3000.

- popup

service: browser_mod.popup
data:
  title: Popup example
  card:
    type: entities
    entities:
      - light.bed_light
      - light.kitchen_lights
      - light.ceiling_lights
  deviceID:
    - this
    - dashboard

will display the specified entities card as a popup on the current device and on dashboard

The optional parameter large: true will make the popup wider.
The optional parameter hide_header: true will hide the header bar and close button.
The optional parameter auto_close: true will make the popup close automatically when the mouse is moved or a key is pressed on the keyboard. This also removes the header bar.
The optional parameter time: (only useable if auto_close: true is also set) will turn the popup into a "screensaver". See the blackout command below.

If card-mod is installed, the popup can be styled by the optional style parameter, or by the card-mod-more-info[-yaml] theme variable.

- close_popup

service: browser_mod.close_popup

will close all more-info dialogs and popups that are open on all connected devices.

- blackout

service: browser_mod.blackout
data:
  deviceID: this

Will cover the entire window (or screen if in full screen mode) with black on the current device. Moving the mouse, touching the screen or pressing any key will restore the view.

The optional parameter time: will make the blackout turn on automatically after the specified number of seconds. It works kind of like a screensaver and will keep turning on until blackout is called again with time: -1.

Note: This will not turn off your screen backlight. Most screens will still emit light in a dark room.

- no_blackout

service: browser_mod.no_blackout

Remove a blackout. The optional parameter brightness will set the screen brightness of a device running Fully Kiosk Browser to a value between 0 and 255.

- lovelace_reload

service: browser_mod.lovelace_reload

Refreshes the lovelace config. Same as clicking "Refresh" in the top right menu in lovelace.

- window_reload

service: browser_mod.window_reload

Forces the browser to reload the page. Same as clicking your browsers refresh button.

- command

service: browser_mod.command
data:
  command: <command>
  <data>

This can be used to send any command to a device by setting command: to the service name and appending any other options.
E.g. the following two service calls will perform the same function:

service: browser_mod.command
data:
  command: toast
  message: Hello World!

service: browser_mod.toast
data:
  message: Hello World!

- commands

service: browser_mod.commands
data:
  commands:
    - command: <command>
      <data>
    - command: <command>
      <data>

This service can be used to call several services listed in the commands: parameter consecutively.

- delay

service: browser_mod.delay
data:
  seconds: <seconds>

Do nothing for <seconds> seconds.

Run a command from the frontend

To run a command from the frontend, you can use the tap_action fire-dom-event with a browser_mod parameter.
E.g:

type: button
icon: mdi:star
tap_action:
  action: fire-dom-event
  browser_mod:
    command: toast
    message: Hello, world!

There's also a special command which is only useful from the frontend:

- call_service

command: call-service:
service: <service>
service_data:
  <service_data>

This works exactly like a call_service tap_action, but if service_data contains the parameter deviceID and that contains the word this, that will be replaced with the current deviced deviceID. This may be useful for e.g. calling scripts if you want to know from where it was triggered.

browser-player card

To control the playback in the current device, browser_mod includes a custom lovelace card. Just add

type: custom:browser-player

anywhere in your lovelace configuration.

The player card also displays the entityID. Click it to select, so you can copy it.

Fully Kiosk Browser

If you are using a device running Fully Kiosk Browser (PLUS version only) you will have access to a few more functions.

For this to work you need to activate Settings->Advanced Web Settings->Javascript Interface (PLUS) and Settings->Motion Detection (PLUS)->Enable Visual Motion Detection.

First of all the commands blackout and no-blackout will control the devices screen directly. no-blackout also has an optional parameter brightness that can set the screen brightness between 0 and 255.

Second, there are a few more attributes available

attribute	content
fullyKiosk	True.
brightness	The current screen brightness.
battery_level	The current charge percentage of the devices battery.
charging	Whether the battery is currently charging.
motion	Whether the devices camera has detected any motion in the last five seconds.

Replacing more-info dialogs

With browser_mod, you can replace any more-info dialog with any lovelace card you choose yourself. This can be done either per lovelace view, or globally (even outside of lovelace).

The replacement is included in your lovelace or lovelace view configuration, and the syntax is exactly like the popup service, except you can't use auto_close or time.

Ex:

views:
  - title: Home view
    icon: mdi:house
    popup_cards:
      light.ceiling_light:
        title: My popup
        card:
          type: entities
          entities:
            - light.ceiling_light_bulb1
            - light.ceiling_light_bulb2
            - light.ceiling_light_bulb3
            - light.ceiling_light_bulb4

This would show an entities card with four bulbs any time the more-info dialog for light.ceiling_light would normally be shown when you're on the Home view in lovelace.

title: My home
resources:
  - url: /local/card-mod.js
    type: module
popup_cards:
  sensor.sensor1:
    title: First sensor
    card:
      type: gauge
      entity: sensor.sensor1
  sensor.sensor2:
    title: Second sensor
    card:
      type: gauge
      entity: sensor.sensor2

This would replace the more-info dialogs of sensor.sensor1 and sensor.sensor2 anywhere in your interface. Even outside of lovelace - be careful about that.

FAQ

Where can I find my deviceID?

The easiest way is to go to /developer-tools/service and call the browser_mod.debug service.

But you can also find the device id on the browser-player card, if you added one to your lovelace config.

An alternative way is to type localStorage["lovelace-player-device-id"] into your browsers console.

Does this replace lovelace-player and lovelace-browser-commander

Yes.

Some improvements

• With the backend support browser_mod does the same things as both of those, but better.
• Since browser_mod uses a service for executing commands rather than events, the commands can be easily triggered by any lovelace element which has a tap_action setting. This actually means it pretty much replaces popup-card as well.
• browser_mod uses websockets to get immediate feedback from the device to the backend and much better tracking of disconnects.
• Aliases. 'nuff said.
• browser_mod works outside of /lovelace.
• This works even if the currently logged in user is not in the admin group.

Does this replace lovelace-fullykiosk

Yes. You need the paid version, btw.

Can the deviceID be used to track me across the internet

No*. The device is stored in your browsers localStorage - a data store which is sandboxed only to Home Assistant. That means only Home Assistant can access it. Furthermore, different Home Assistant installations cannot acces each others localStorage.

Some of my lovelace plugins use the device to do different things for different devices.

*There is one exception. If you are using Fully Kiosk Browser, the deviceID is taken from the browser instead of being randomly generated. This deviceID will be the same for each website that asks for it.

My Fully Kiosk Browser device goes unavailable after the screen has been turned off for five minutes

This seems to be a problem with Android, and not much to do about it. As a workaround you can add the following to your configuration:

browser_mod:
  devices:
    d2fc860c-16379d23: # DeviceID of your FKB device
      force_stay_awake: true

That will make the screen turn on and off again for a second regularly to stop the five minute timer from running out.
