74Build a fully local, privacy-respecting smart home with Home Assistant and devices from AliExpress.
Home Assistant is the leading open-source home automation platform, and AliExpress is the best source for compatible devices. Zigbee sensors, ESP32/ESP8266 boards, and Tuya devices can all be integrated into a local, privacy-respecting smart home.
Key factors to consider before buying on AliExpress
Zigbee devices with Zigbee2MQTT offer full local control — no internet needed. ESP32/ESP8266 devices can run Tasmota/ESPHome for 100% local operation.
Not all Zigbee devices work with all coordinators. Check the Zigbee2MQTT compatibility database. Tuya devices can be local via Tuya Local or cloud via Tuya integration.
Some WiFi smart plugs and switches use ESP chips that can be flashed with Tasmota or ESPHome for complete local control. Check the device chipset before buying.

The Sonoff ZBDongle-P ($15-20) is the most recommended. The Home Assistant SkyConnect ($30) offers Thread/Matter support.
Older Tuya plugs with ESP chips can be flashed. Newer ones use BK7231 chips — these require different firmware (ESPHome/OpenBeken).
