Cannot get Shelly1 MQTT working

[Kranendijk]

Hi all,

I have a Shelly1 flashed with Tasmota and have setup MQTT on it. Now when I press the "Toggle" button in the web interface of the Shelly I receive in the Domoticz log the below 2 lines:
2019-11-30 17:59:47.067 MQTT: Topic: domoticz/in, Message: {"idx":30,"nvalue":1,"svalue":"","Battery":100,"RSSI":7}
2019-11-30 17:59:49.048 MQTT: Topic: domoticz/in, Message: {"idx":30,"nvalue":0,"svalue":"","Battery":100,"RSSI":6}

This indicates (to me at least) it is sending data to the MQTT broker which is installed on the Pi Domoticz is running on. Also the idx is the idx I entered on the Shelly and this is the idx of my dummy device light switch.

However the status of the device is not set in Domoticz, neither can I toggle on/off from within Domoticz. I can press the device, it tells me it is switched on, but it isn't.

What step am I missing here? MQTT is working, my other MQTT device (a home built weather station) is transmitting to Domoticz perfectly.

Thanks!

And some pictures. MQTT config in Shelly:

And the device in Domoticz. As you can see it updates the last seen status after I pressed the toggle button in the Tasmota web interface:

And some logging in Domoticz when I toggle the switch:
2019-11-30 18:57:19.918 (MQTT) Light/Switch (Gang)
2019-11-30 18:57:19.905 Status: User: Admin initiated a switch command (30/Gang/On)
2019-11-30 18:57:23.509 (MQTT) Light/Switch (Gang)
2019-11-30 18:57:23.497 Status: User: Admin initiated a switch command (30/Gang/Off)

Solved. Had to set the publish topic in Domoticz to out instead of hierarchical. Now that solved this issue, let's see what happens with mqtt now as I was advised to set the publish topic to hierarchical due to flooding mqtt messages and hanging my pi...
