Connecting Xiaomi temperature sensors to MQTT... please help

ESPHome
1

Hi, Hopefully someone can help. I would like to try to connect 3 Xiaomi BLE temperature/humidity sensors to MQTT via ESPHOME. However, I do not get it to work.

I have 3 sensors:

  1. LYWSD03MMC. original firmware
  2. LYWSD03MMC. custom firmware
  3. Xiaomi mija (round device).

I have an external MQTT broker. It only receives values of device 1. Temperature/humidity and battery level is received.

The ESP32 is flashed via home-assistant esphome. Works well. all 3 devices are found via the ble-tracker of the esp.

I tried already all names with and without the "… do difference.

I have the following ESPHOME configuration. What am I doing wrong?

esphome:
name: abititer_t_bridge
platform: ESP32
board: mhetesp32devkit

wifi:
ssid: “XX”
password: “XX”

logger:
level: debug

Enable Web

ota:
