Sync Home Assistant Lights With the Sun
Static brightness and color settings can make a smart home feel out of step with the day. Adaptive Lighting uses Home Assistant’s sun data to set cooler, brighter daytime light and warmer, dimmer evening light, while keeping manual controls available and requiring no custom lighting hardware.

Small enough for tight enclosures, the ESP32-C3 Super Mini still offers Wi-Fi, Bluetooth, useful GPIO, and a deep-sleep mode. This hands-on guide moves from pinout and Arduino IDE setup to a local web server and timed wake-up test, showing where the board fits in battery-powered IoT projects.

An old Intel board can make a useful router, but this build hit a software snag: OpenWrt booted while its missing e1000e module hid the 82574L ports. The project then tests OPNsense, weighing a lightweight setup against a fuller firewall platform and showing why drivers matter.

Solar equipment can report far more than a single production number. This Home Assistant integration reads supported Huawei Solar data and functions through Modbus, then presents them as entities for dashboards and automations. Setup depends on compatible hardware, a reachable interface, correct addressing, and sensible polling intervals.

Battery life depends on more than an ESP32’s sleep-current figure. This practical guide lays out a wake, measure, transmit, and sleep pattern for soil monitors, weather stations, and other remote devices, while covering wake sources, retained state, wireless costs, board leakage, and realistic runtime estimates.

A BLE radio can reveal device names and other details before any pairing happens. GhostBLE turns that lesson into a pocket tool: an M5Stack scans nearby advertisements, shows devices on its display, and flags privacy concerns, giving makers a practical way to inspect their own homes, labs, and prototypes.

Alarm sounds and sensor changes need not stay inside an ELRO Connects system. This custom Home Assistant integration reads K1 and K2 hubs directly, bringing immediate events, battery levels, signal strength, and device states into local automations. The two hub generations use different communication software, so hardware identification matters.
