Hey everyone, I’ve been diving into optimizing my smart home dashboard lately, and I thought I’d share my journey and some insights. I love a clean dashboard, one that only shows essential information when needed. To achieve this, I’ve been using a Markdown card to display status messages. Ideally, it’s empty, but it can look like this: 
However, as I started querying more devices, the dashboard became sluggish. It was frustrating, especially when my Android tablet would take forever to load the dashboard after detecting motion. I realized the issue was the dashboard rebuilding the page each time, querying multiple entities in the process. To tackle this, I began creating a template sensor where I could store status messages. Now, the dashboard only needs to fetch the status from a single sensor, significantly speeding things up.
But then came the learning curve—literally! I discovered that the status text was limited to 255 characters. While this works for simple messages, it’s a bit restrictive when dealing with multiple status updates. I’m curious if anyone has found alternative solutions or methods to display more information efficiently on the dashboard. Maybe there’s a smarter way to structure the data or utilize other sensors?
If you’ve encountered similar challenges or have tips on optimizing dashboard performance, I’d love to hear your thoughts! Let’s brainstorm together and find the best approach to keep our dashboards sleek and responsive. Happy automating!
