DIY smart mirror surge
DIY guides are showing how to convert a regular mirror into a Home Assistant‑powered command center in five steps — weather, calendars and headlines on a Raspberry Pi display. ( ) Enthusiasts are also pushing fully‑local Home Assistant installs on Raspberry Pi for privacy, energy savings, auto‑lights and presence detection without cloud dependence. ( )
The open-source MagicMirror² project has more than 23,000 stars on GitHub and released version 2.34.0 in recent months, underscoring an active developer community for DIY mirror displays. (github.com) Home Assistant hit roughly 2,000,000 active installations worldwide in 2025 and its May 2025 release bundled backup and automation improvements that users often deploy to mirror dashboards. (androidpolice.com) Home Assistant’s official Raspberry Pi installation notes recommend using a Raspberry Pi 5 or Raspberry Pi 4 with at least 2 GB of RAM and an A2‑rated microSD card for reliable local installs. (home-assistant.io) Measured power figures put a Raspberry Pi 4 at about 0.1 kWh/day if left running 24/7 and a Raspberry Pi 5 around 0.2 kWh/day in typical use, which translates roughly to 36.5 kWh/year and 73 kWh/year respectively — figures hobbyists cite when arguing mirror setups cut energy versus a full PC. (astronomy.me.uk) Home Assistant supports multiple presence methods that mirror projects use for auto‑lights and personalized displays: the Companion app’s GPS/location device tracker, router/Wi‑Fi‑based device trackers, BLE/ESP32 beacon scanners for room‑level detection, and community “person” aggregators that fuse multiple trackers into one presence entity. (home-assistant.io) Community guides and writeups document fully local, “no‑cloud” Home Assistant builds (including local voice and LLM experiments) and step‑by‑step migrations of cloud‑dependent devices to local integrations, reflecting why many users opt out of analytics and keep control on‑prem.
