Reaction on MQTT command

I am trying to control my shelly plug S via MQTT.

I use Mqtt explorer to see if the messages arrive correctly.

The shelly is reporting its state correctly.

When I sent a message with the same topic and content no reaction is observed. The plug does not switch on or off.

How can I get the plug to react?

I managed to solve the problem

The topic to publish the command to should read:

"shellies/appliance id/relay/0/command"

The commands are: on, off or toggle

e.g.:

mqttClient.publish("shellies/fan/relay/0/command", 0, true, "toggle");

mqttClient.publish("shellies/fan/relay/0/command", 0, true, "on");

mqttClient.publish("shellies/fan/relay/0/command", 0, true, "off");
