Devices for local smart homes

Sonoff B02-BL-A60 smart Wi-Fi LED bulb E27 9 W 806 lm

When an ordinary bulb burns out, screw this one into the same E27 socket and the room gains scheduled warm-to-cool white, a gentle wake-up light and phone control — no hub needed.

Avatto ZWSM16-W1 Zigbee 1-gang in-wall switch module, with neutral

A single-channel Zigbee 3.0 relay that hides in the back-box behind the key and keeps the light on a local mesh through a Tuya Zigbee gateway, off the home Wi-Fi.

For Zigbee2MQTT experiments and a small network of up to ~20 devices this legacy CC2531 dongle still does the job — no external antenna, firmware updates need a programmer.

Reads room temperature and humidity on a 1.5" LCD, powered by a Sensirion sensor with Bluetooth sync to the Xiaomi Home app.

One tap fires a whole scene — a Xiaomi Zigbee button with single, double and long press, stuck anywhere with adhesive tape.

Stick the two halves on the door and frame: the moment the door or window opens, the ZDS16 sends a Zigbee alert to your phone.
