Matter and Thread keep tightening the smart‑home playbook — new primers show Matter/Thread‑certified devices plus sensors and tags now available for under $10, making future‑proof setups genuinely affordable. Longtime Home Assistant users also argue for self‑hosted control — one veteran reports running Home Assistant for 6+ years to coordinate power, cooling and solar, underscoring a DIY path that pairs well with inexpensive Matter gear.
