Please help connecting to Home Assistant

[adoucette]

How do I go about connecting the device to Home Assistant by Zigbee or MQTT?
I believe I have built the zigbee2mqtt example and uploaded it to the LilyGo T-Zigbee device. (my steps here(https://github.com/Xinyuan-LilyGO/T-ZigBee/issues/21#issuecomment-1566196339)) Prior to building, I made the following edits in the code:

1. data/db.json: set the wifi router ssid and pwd, set the zigbee channel to what my MQTT server is using (15), set the MQTT server ip, port, username, and password
2. zigbee2mqtt.ino: set the wifi router ssid and password, the mqtt server ip, port user, and password; set the "zbhci_BdbChannelSet" to my MQTT server channel (15)

Then in VS Code I can build and upload it to the device. Then in the VS Code terminal window I see that the device connects to my wifi, but is not connecting to MQTT. I have held down the "Key" button on the device to set it into pairing mode (blue light on chip opposite corner from the USB input is slow flashing).

Here is some output from the terminal window:

--- Terminal on COM6 | 115200 8-N-1
--- Available filters and text transformations: colorize, debug, default, direct, esp32_exception_decoder, hexlify, log2file, nocontrol, printable, send_on_enter, time

In HA I don't see it as a zigbee device to add.

How do I get this connected to HA?

Without understanding anything, I bought 3 modules. Now this garbage is lying in a box and waiting for the manufacturer to write at least something that works.

Same. Looking forward to ESPHome support for the latest version chips since some of those have Zigbee and Thread connectivity.

Maybe this could help: https://github.com/Xinyuan-LilyGO/T-ZigBee/pull/24 - No clue why this simple easy pull request is never merged
