Tasmota - MQTT - HomeAssistant

How to integrate ESP32 Tasmota device sensors to Home assistant via MQTT

• https://tasmota.github.io/docs/Getting-Started/
• https://www.home-assistant.io/integrations/tasmota/
• https://tasmota.github.io/docs/Home-Assistant/
• http://www.steves-internet-guide.com/topic-restriction-mosquitto-configuration/

Configure steps:

• HA : If using the Mosquitto Broker add-on for Home Assistant, first create a new Home Assistant user under Settings > People.
  • mqtt_broker_user
• HA : Integrations >> MQTT Settings >> RE-CONFIGURE MQTT
  • Username: mqtt_broker_user (former:homeassistant)
  • Password: xxxxx
• TASMOTA : Then, in Tasmota > Configure MQTT under “Host” enter the address of your Home Assistant instance and under “User” and “Password” enter the Home Assistant user you just created.

  • add missing capacitor C24 = 100uF
    RF TX consumption depends on the power supplied to the antenna.
    This is a short impulse and does not greatly affect the overall consumption.
    But xiaomi saved one cent on tens of thousands of devices and didn't put a capacitor into the PCB.
