The Sonoff ZBBridge-P pairs an ESP (Wi‑Fi MCU) with an EFR32MG21 Zigbee radio and exposes a serial‑over‑TCP bridge: with Tasmota it provides local Zigbee support (ZHA, Zigbee2MQTT or Zigbee2Tasmota) and lets you place a gateway anywhere on your network. Good choice if you want a network‑attached Zigbee coordinator (ESP serial bridge + Zigbee firmware), but expect a two‑stage flashing process, manual wiring (3.3V TTL, GPIO0 short to enter bootloader) and occasional stability caveats of Wi‑Fi serial bridges.
For tinkerers and Home Assistant users who want a networked Zigbee coordinator and are comfortable flashing firmware and wiring 3.3V TTL; avoid if you need plug‑and‑play USB simplicity.
