I’ve been diving into the world of smart lighting automation lately, and I must say, it’s been a fascinating journey! One of the challenges I’ve encountered is ensuring that all my lights maintain a minimum brightness level when turned on. After some research and experimentation, I stumbled upon the idea of using templates to streamline this process.
Here’s what I’ve discovered so far: By leveraging the states[domain] function in templates, I can dynamically pull a list of currently active lights along with their brightness settings. This approach seems promising, but I’m hitting a snag when it comes to extracting the entity IDs and brightness values from the template output. I’ve tried several methods, but none have worked seamlessly yet.
My plan is to create a single automation that can handle this for all lights, rather than setting up individual automations for each bulb. The pseudo-code I’ve drafted looks something like this:
Trigger: - lights_on_count != saved lights_on_count
Action: - update saved lights_on_count
- extract all brightness and entity ID out of the fields
- condition continue if any brightness value is less than my desired minimum
- set the lights with brightness lower than minimum to minimum using service call
I’d love to hear from others who’ve tackled similar challenges. Have you found a way to efficiently extract and manipulate this data within templates? Any alternative approaches or tips would be greatly appreciated! Let’s keep the conversation going and help each other refine these smart lighting solutions.
