Devices for local smart homes

Smlight PoE Extender 1-to-2 100Mb passive 802.3af splitter, +100 m

Passive PoE splitter that turns one 802.3af line into two outputs and carries data plus power another 100 m — to power SLZB-06 coordinators where there is no socket.

Avatto ZWS16 Zigbee water leak sensor IP66 with local siren

Sat under the sink or by the washer, the ZWS16 senses the first drops, sounds a local alarm and pushes a phone alert through a Zigbee gateway.

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.

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.
