Home Assistant On Wheels: We’re going Inside the SmartyVan
Home Assistant Podcast
Rewiring Sensors: Batteries vs. Hardwired
Mike compares Zigbee battery sensors with hardwired reed switches and explains choices for reliability.
Director-turned-vanlifer Mike from the YouTube channel SmartyVan shows how he turned a bare Mercedes Sprinter into a fully automated, off‑grid smart RV powered by Home Assistant and ESPHome. We cover DC power realities, alternator charging vs solar, Starlink on the move, Bluetooth presence, wired vs Zigbee sensors and PoE cameras with Frigate. Perfect for vanlife, RV, and tiny home builders.
