Good evening @sailmich

I took a look into shellies API and found that the plug is also sending energy
That is correct, but it depends on the type of plug (generation 1 or generation 2), how to format the request.
it can be done and then it is a simple conversion.
Can you tell me, what the type of your plug is?. Is it a Shelly Plug or PlugS (Generation 1) or is it a Shelly Plus Plug S (Generation 2)
keep in mind that the value you receive from the Shelly for "Energy" is expressed in Wm (Watt-minute) So 1 Wm = 1/60 Wh
I got a solution with http but would like to do it with mqtt.
That is possible. I created something quick with an "Inject" node, (as I do not know the Generation of the Shelly yet)
See the flow below in order to give you an idea.

If crashing the dummy device by false values isn't a bug, could someone please move the tread.
I do not see it as a bug, but injecting wrong or no values in the Domoticz database is not a good idea.
But I agrre it would be better, that it would reject the value.
Personally I have never been able to crash Domoticz by injecting something wrong.
So to send it by MQTT, you need
1. Configure your Plug, Plug/S Plug Plus to use MQTT
2. Use to MQTT Explorer to check the communication
3. Let me know the type of plug.
Have a look at the example.

I got a solution with http but would like to do it with mqtt. I still don`t now how to get booth values together and sent it via mqtt. May you help me.
