Shelly Plus 2PM doesn't post changes via MQTT

[Meinhard-Risch]

I've flashed a Shelly Plus 2PM with the tasmota32solo1.bin. Everything works fine. Over the Web it is possible to toggle the relais. Switchmode 3 is set. The connection via mqtt is stable. I'm able to set the POWER 1 and the POWER2 to false or true to switch the relais ON or OFF. But the result is never talked back to the MQTT-Server. The Tasmota-Device doesn't publish any changes. The telemetry period is set to default (300).
I hope, someone could help.

Which mqtt broker? Mosquitto? Version?

You may have ACL enabled

[Meinhard-Risch]

Its MQTT via SONOFF-Adapter in ioBroker. Sorry, but what does it mean: ACL?

[Meinhard-Risch]

Oh sorry, now i'm clear: No, there is no Acces-Control-List.

I don't know ioBroker but if Tasmota is connected, can receive commands from MQTT but is not successfull in publishing, I would bet it is problem with ioBroker configuration.

Do make sure that Tasmota has a working MQTT connection. When powering on, I see such in the Tasmota console:

22:53:18.530 MQT: stat/devicetopic/POWER = {"POWER":"ON"}
22:53:18.532 MQT: stat/devicetopic/POWER = ON

If you get RSL: instead of MQT:, Tasmota did not reach the broker.

Thank you barbudor for helping. I just restarted the device and got the following in the console:

I Think, it looks normal ...

Then Tasmota is doing the publish operations. If you do not see that in ioBroker, make sure that you do the subscribes right, and if the MQTT setup is "connected right".

[Meinhard-Risch]

Hi barbudor, you've won (I would bet it is problem with ioBroker configuration.)!
I just wrote a little javascript to attach another light to the endpoint. And what should I say. The stat is written at the endpiont of MQTT-Server, but the value is not shown by the sonoff-adapter. I'm sorry to waste your time. Thank you!
