Fixed: MQTT - Wrong topic in response to a command topic

[s89511]

I'm using 5.3.0 release.

I configured my sonoff basic with topic = sonoffbasic01 fulltopic = tasmota/garden/light/%topic%/%prefix%/

When I send the MQTT message tasmota/garden/light/sonoffbasic01/cmnd/POWER ON the device reply with stat/sonoffbasic01/RESULT = {"POWER":"ON"} stat/sonoffbasic01/POWER = ON

Is this the expected behaviour? It used the old topic format and not the configured fulltopic.

I think I'm running into a similar issue in v5.6.1b (on a Sonoff Basic, rebuilt on the latest version just now).

When sending the command: tasmota/sonoffbasic1/cmnd/Power1 TOGGLE

The response I receive is: stat/sonoffbasic1/POWER OFF

However, if I press the Button on the Sonoff Basic (or flip the switch connected to GPIO14), I get a the MQTT message: tasmota/sonoffbasic1/stat/POWER OFF

(SwitchMode and SwitchTopic are the default values.)

Pls provide output of commmand status 0.

I suspect your topic is equal to fallbacktopic = mqttclient.

Thanks!

I think I'm missing something as I don't see a fallbacktopic (below or in the docs) :/

Here is the output of both status0 and status 0 (slightly sanitised).

As said fallbacktopic = mqqtclient name.

Your mqttclient name is "Sonoffbasic1". Your topic name is equal. This results in your experienced behavior because for Tasmota they need to be different.

• The mqttclient name needs to be unique for MQTT as the client.
• The mqtt topic may be unique too to address a specific device.
• Tasmota subscribes to both topic name AND mqttclient name (as fallback topic name in case you messed up with your topic name). The fallback topic name result message is always stat/mqttclientname/result.
• The topic name result message uses the fulltopic structure only.

SOLUTION: Make your mqttclient name unique AND different from topic name.

[sillyfrog]

That sorted it, thanks!

Changing the Client Id to be different from the Topic means the generated FallbackTopic will now be different. If possible, it would be great to update the Web UI with a hint to keep the two fields different (as I left the rest as the default) for us newbies :)

Thanks again for you prompt help, really appreciate it!

[s89511]

Thanks. I changed MqttClient and now it works as expected.

This is great 👍

Thank you very much for your support.

@arendst Getting the same issue but Client, Topic and Fallbacktopic are distinct so the fix mentioned in this thread does not work.

I have multiple tasmota devices configured and I am unable to send a MQTT command to the tasmota devices from one to another. The response is coming back with information from the current devices and not from the remote device.

As an example, here is a mqtt command from "display" to "D1miniUG".

I copied console output from both devices,
