You can stream live vehicle diagnostics and GPS location to Home Assistant by pairing a Bluetooth Low Energy OBD-II adapter with an ESPHome -based BLE proxy or a dedicated Android device running Torque Pro . This setup feeds real-time fuel economy, engine codes, coolant temperature, and GPS coordinates into Home Assistant entities, enabling geo-fenced automations like opening your garage door on arrival or logging trip fuel costs - all without any cloud dependency.

Deploy at least two Thread border routers and connect them to the same Thread network. Each can be an Apple HomePod Mini, a Google Nest Hub (2nd gen), or a DIY OpenThread Border Router (OTBR) on a Raspberry Pi. This gives your Matter -compatible smart locks, sensors, and lights a reliable IPv6 path to your IP network. They can then talk to Home Assistant , Apple Home, and Google Home at once through Matter’s multi-admin feature. Two routers is the minimum for any network you depend on. If one goes down, the other keeps your mesh alive.

Running Home Assistant OS (HAOS) inside a Proxmox VE virtual machine gives you the full, officially supported installation - add-ons, Supervisor, automatic updates - while sharing hardware with other VMs and containers. On a modest Intel N305 mini PC, you can run HAOS alongside Plex, Vaultwarden, Nextcloud, and a WireGuard VPN with room to spare. The entire setup takes under 30 minutes. Download the HAOS QCOW2 image, create a VM in Proxmox, import the disk, boot, and you are up and running.

Home Assistant Blueprints are reusable automation templates. They split the logic from the per-device bits. You define a pattern once, say a motion light with a timeout, then spin it up for every room by filling in a form. No YAML to copy. No ten near-twin automations to babysit. In Home Assistant 2026.4, blueprints span three domains: automation, script, and template. They ship dozens of selector types for clean input forms and tidy collapsible sections for bigger setups. They’re the fastest way to keep smart home behavior the same across many devices.

Yes, Home Assistant ships a built-in conditional card. It shows or hides any dashboard card based on live state: entity value, time of day, who is home, screen size, and more. Add template sensors and a few HACS cards, and you can build dashboards where morning shows weather and coffee buttons, evening shows media and light scenes, and an empty house shows cameras and alarm controls. Cards pop in and out without leaving blank gaps, all through the stock Lovelace frontend. No custom code needed.

You can use HDMI-CEC commands through Home Assistant ’s HDMI-CEC integration - or a CEC-capable device like a Raspberry Pi running cec-client - to control TV power, input switching, and volume from automations and dashboards. Instead of juggling three or four remotes, you wire up a “Movie Mode” automation that dims the lights , powers on the TV, switches to the correct HDMI input, and sets volume to a comfortable level. One tap. Done.
