[Feature Request] Compatibility with "SONOFF Zigbee Bridge Pro" (ZBBridge-P) based on ESP32 and CC2652P

[Hedda]

This request comes a little ahead of its time since this ITead Sonoff ZBBridge-P is not available to buy yet, but it will be soon ;)

UPDATE! ZBBridge-P (a.k.a. "ZB Bridge-P") has now been released as "SONOFF Zigbee Bridge Pro" as is now available for purchase:

https://itead.cc/product/sonoff-zigbee-bridge-pro/

FYI, FCC leak show CC2652P and ESP32 based Sonoff ZBBridge-P v1.1 Zigbee Bridge coming from ITead.

https://fccid.io/2APN5ZBBRIDGEP

Internal pictures posted from FCC show using an unannounced Texas Intruments CC2652P (CC2652P1) MCU chip based “SM-031 v1.1” radio module which must be made by CoolKit (the company that makes their EFR32MG21 based “SM-011 V1.0” module).

ESP32 has replaced the ESP8266/ESP8285, and it also looks like added an on-board clock-battery too, presumably for RTC (Real-Time Clock)?

FFC also leaked new Sonoff branded Door/Window Sensor, Motion Sensor, Temp/Humidity Sensor, and a Button as wireless Zigbee devices, all with the same CCC2652P (CC2652P1/CC2652P1F) chip which +20 dBm capable power amplifier is really overkill for battery-operated sensors and should on theory use more battery power than if they would have used the compatible CC2652R or CC2652RB.

Sadly it looks like even this new variant of Sonoff ZBBridge still uses Wi-Fi instead of wired Ethernet network like the newer ZB-GW03:

Ethernet is preferred by DIY users who flash Tasmota or ESPHome in order to use it as a remote Zigbee adapter with ZHA or Zigbee2MQTT because tunnelling serial communication over a serial stream server connection and the serial APIs of the Zigbee stacks are not robust/stable over WiFi as assume a direct connection, which is why both ZHA and Zigbee warns against using WiFi-based networked-attached Serial-to-IP Zigbee bridges/gateways/adapters:

According to digiblur who broke this news, these are slated to be released in March of 2022:

Not sure if this is intended to permanently replace the popular ITead Sonoff ZBBridge

As I understand ITead have not abandoned Silicon Labs yet but it is just that Silabs chip stocks have suffered worse than most other companies during the still currently ongoing worldwide chip shortage.

PS: Assume it will use the same firmware for CC2652P as “Sonoff Zigbee 3.0 USB Dongle Plus”:

FYI, both NotEnoughTech and digiblur have received theirs and while neither of them has tried to flash/hack it yet they posted some early thoughts on the original eWeLink hub firmware and hardware board, confirming that the first retail version ITead's SONOFF Zigbee Bridge Pro with PCB board labelled "ZBBridge-P V1.1 2021.11.12" is indeed based on Espressiff ESP32-DOWD-V3 (that ESP32 variant by the way also has integrated support for Bluetooth 4.2 including BLE), Texas Instruments CC2652P Zigbee module labelled "SM-031 V1.1 2021.07.28" (so probably manufactured by CoolKit Technologies like the Zigbee module for previous Sonoff bridge), with a cell-battery for the RTC (Real-Time-Clock), a built-in buzzer for chime or alarm-siren, and also an Espressiff branded PSRAM (ESP-PSRAM16H) with 2MB/16Mbit capacity.

digiblurDIY also mention that he managed to backup original firmware from ESP32 without issue so suspect that it is not locked:

As there is still no progress here I've created a configuration for the ZBBridge-P here: https://jonasled.dev/jonasled/sonoff-zigbee-bridge-pro-esphome

@jonasled Nice! Will you consider adding mDNS and "TXT record" for Zeroconf discovery by Home Assistant's ZHA integration?

FYI, @Giancky79 also created an ESPHome configuration for Sonoff ZBBridge-P bridge here:

Thx, i hope is a valid alternative 😅
