Integration discovery is not supported

Currently running HA in a docker environment. No supervisor.

Ever since updating to 0.115.2 I have been getting a warning in the log upon startup similar to this:

2020-10-06 23:22:27 WARNING (MainThread) [homeassistant.components.mqtt.discovery] Integration discovery is not supported

Details show in part:
Logger: homeassistant components.mqtt discovery
Source: components/mqtt/
First occurred 3:33:29 AM (5 occurrences)
Last logged: 3:33:29 AM
Integration discovery is not supported

I have three devices using the MQTT integration. All are running the latest version of Tasmota.

I have received this warning whether I had MQTT defined in the configuration.yaml file or defined in the MQTT integration module (and commented out in configuration.yaml).

Does anyone know why this warning is occurring?

Any suggestions on a fix? I am running out of ideas to try.


You did enable discovery ?

  port: 1883
  discovery: true
  discovery_prefix: homeassistant
  username: xxx
  password: xxx
    topic: 'hass/status'
    payload: 'online'
    topic: 'hass/status'
    payload: 'offline'  



Thank you for your response.

Yes, MQTT discovery was enabled in the configuration.yaml file

  broker: !secret mqttbroker
  port: !secret mqttport
  username: !secret mqttusername
  password: !secret mqttpassword
  discovery: true
  discovery_prefix: homeassistant

I also reset the tasmota devices in question. Still getting the warning.

Appears to have been a problem with MQTT probably a retained message. I redeployed MQTT and the warning appears to have gone away.
