Home Assistant dashboard:
Wake-up alarm light

Home Assistant logo

Here you find an explanation of a Home Assistant dashboard with an alarm timer on it which can be changed via the dashboard itself. This way dashboard users can make modifications to the ON and OFF time of an entity.

wake-up dashboard

This can be used, for example, as wake-up ceiling LED strip light. Any automation can be triggered on this time! Start streaming a radio channel, creating a coffee, announce the weather forecast, news, traffic.

Hardware

Zigbee RGB LED strip

The hardware I used for this project is a dump LED strip, modified to work direct on power without a switch and controlled by a smart socket. As alternative a smart LED strip controlled by Zigbee/WiFi can also be used for it.

With a smart wireless button it’s possible to manually control the LED strip state.

Home Assistant config

To define the timer and (de)activate toggle on the dashboard, custom helper entities are created.

Dashboard

This is how the final dashboard could look like. Manual trigger the LED strip, toggle the timer. And set the ON and OFF time.

You can easily add more times if you prefer.

wake-up dashboard

This is the corresponding YAML code:


# Sourcecode by vdbrink.github.io
# Dashboard Entities card configuration YAML
type: entities
entities:
  - entity: switch.blitzsmartplug_led
  - entity: input_boolean.wake_up_active
  - entity: input_datetime.ledstrip_on_time
  - entity: input_datetime.ledstrip_off_time
state_color: true
title: LED strip
show_header_toggle: false

Entities

The dashboard is build up of four entities:

  • An entity to control the LED strip.
    • In this case switch.blitzsmartplug_led
  • A helper entity for the time the LED strip will be turned ON.
    • In this case input_datetime.ledstrip_on_time
  • A helper entity for the time the LED strip will be turned OFF.
    • In this case input_datetime.ledstrip_off_time
  • (Optional) A helper entity to skip the timer.
    • In this case input_boolean.wake_up_active

In the next chapters I’ll explain how to create these helpers.

Timer helper entities

First, we create a time selector on the dashboard.

Go to the Settings menu item, then go to Devices and Services and select Helpers in the top bar.
This button directly opens the Helpers page in your Home Assistant:

Open your Home Assistant instance and show your helper entities.

Select the bottom-right button + Create Helper, select Date and/or time. Create helper button


Give it a name (this will also automatically be used for the entity name).
Optional select an icon, like mdi:clock.
Select the input type Time.



Follow the same steps to also create the OFF helper entity.

Boolean helper entity

For the extra helper to skip the ON/OFF timer (on a free day for example).

Create a new helper and this one should be of the type Boolean.
This entity has two states: true for active, false for inactive.

HA create boolean is helper active

Automation

I have my automations in Node-RED.
I use the created HA helpers as Nodes in my automation flows.

This is my flow: Node-RED wake-up flow

The first flow, to control the LED strip manually with a smart button, is build up with these nodes:

  • In node (this node is part of the module node-red-contrib-zigbee2mqtt) which is triggered when the button is pressed.
  • Change node to set the state toggle to the payload.

The second flow, to turn ON the LED strip based on the OFF time, is build up with these nodes:

  • HA time node which is triggered at the defined ON time.
  • HA current state node which checks of the flow should continue or stop.
  • Change node to set the state ON to the payload.
  • Zigbee2MQTT out node where the smart socket or LED strip is defined.

The third flow, to turn OFF the LED strip based on the OFF time, is build up with these nodes:

  • HA time node which is triggered at the defined OFF time.
  • HA current state node which checks of the flow should continue or stop.
  • Change node to set the state OFF to the payload.
  • Zigbee2MQTT out node where the smart socket or LED strip is defined.

This is the config of the HA time node which trigger an event when the defined time is reached:

HA time node config

This is the config of the HA current state node which check if the timer should be active:
