Yaml

Gatus is a single-binary monitoring tool that probes your services and shows a public status page at a URL you control. You define every check in one YAML file. So your whole setup can live in Git next to the rest of your stack. There is no need for a database, no web UI to click through, and no per-monitor pricing. If you self-host a blog, a Gitea instance , a Home Assistant server, or a mail relay, Gatus gives you a simple way to know when something breaks.

You can secure your Home Assistant config by pushing your YAML files to a private GitHub repo on a daily schedule. This gives your smart home version control. You can see what changed between the last working state and the broken one, roll back a single file in seconds, and rebuild a fresh HA install from a repo clone. It is faster and far more useful than the built-in snapshot backup for config-level problems.

A professional Home Assistant dashboard uses custom CSS Grid layouts and HACS cards like button-card to build responsive, mobile-first interfaces. Moving past the default grid lets you design a “control center” that looks like a native high-end app, not a scrolling list of toggles. This guide walks through every layer of that change. It covers why the default UI falls short, the CSS Grid basics you need, how to build a clean theme, how to structure room-based navigation, and how to make it all work well on the HA Companion App.

Bayesian sensors in Home Assistant give you one reliable presence signal by fusing weak ones: phone Wi-Fi, GPS zones, motion, power draw, and more. The bayesian platform doesn’t ask “is this one sensor on?” It asks “given everything I can see right now, how sure am I that someone is home?” The result is a presence system that tolerates dropouts, handles sleeping occupants, and stops the lights clicking off while you’re still on the couch.

Your home’s lights are one of the best levers for better sleep, and you can set most of it on autopilot. Pair motorized blinds driven by Home Assistant solar elevation data with the Adaptive Lighting HACS integration. The combined setup shifts light and blind positions through the day, in step with your body clock. The result: a gentler wake-up, a calmer wind-down, and better sleep.

The Science of Circadian Lighting

The human circadian system is keenly sensitive to light. The intrinsically photosensitive retinal ganglion cells (ipRGCs) in the eye react strongly to short-wavelength blue light in the 470 to 490 nm range. Cool bluish light, typically in the 5000K to 6500K color range, blocks melatonin and tells the brain it’s daytime. Warm light in the 2200K to 2700K range mostly falls outside that band and won’t trigger the same response, so it’s safe (and even helpful) for evening use.

When you have one automation watching multiple switches, you don’t need to hardcode which one to turn off. You can use the trigger object to dynamically target whichever device started the automation.
