I’ve been diving into the world of smart lighting automation lately, and it’s been an exciting journey! One of the features I’ve been most curious about is setting up a double-click button to toggle between different brightness levels for my LIFX lights. While I’ve managed to get the basics down, there’s been a bit of a learning curve along the way.
Here’s the setup I’m working with: I have Xiaomi wireless buttons paired with my LIFX WiFi lights. A single click toggles the light on or off, which is straightforward and works perfectly. The challenge has been configuring a double-click to switch between 50% and 100% brightness. I’ve been experimenting with different data_template settings in Home Assistant, but it’s been a bit of trial and error.
My current configuration looks like this:
yaml
service: light.turn_on
data_template:
entity_id: light.bedroom
brightness: >
{% if states.light.bedroom.attributes.brightness > 240 %}
130
{% elif states.light.bedroom.attributes.brightness < 150 %}
250
{% endif %}
The goal here is simple: if the brightness is above 240 (which I consider bright), it should dim to 130. If it’s below 150 (dim), it should brighten to 250. However, when I double-click the button, I run into an error: Invalid service data for light.turn_on: expected int for dictionary value @ data['brightness']. Got ''. It’s a bit frustrating, but I’m determined to figure this out!
After some research, I realized the issue might lie in how the brightness value is being handled. The current setup seems to be returning an empty string instead of a numerical value, which is causing the error. I’m now exploring alternative ways to structure the template to ensure it always returns a valid integer. Maybe adding default values or adjusting the conditional logic could help.
This experience has been a great learning opportunity. It’s reminded me how important it is to thoroughly test configurations and not be afraid to tweak things until they work perfectly. I’m hopeful that with a bit more tweaking, I’ll have a seamless double-click brightness toggle system up and running!
If anyone has tips or suggestions on how to refine this setup, I’d love to hear them. Happy automating!
