You need to give us a bit more detail to work on as your description is very vague.

Post a flow if you can... but first read how to do that.

The easiest way to do that is to click the 'Preformatted Text' button in the toolbar: [image] Then paste in your code or flow json. You should end up with three back-tick characters - ``` - on their own line before and after the code. On standard US English keyboards, this is on the same key as the ~ character. Using the backticks will ens…

If you select the nodes that you have in the screenshot, and then export the flow, you will be able to paste it here (after reading the link which @dynamicdave posted above).  
Then we will be in a better position to help you.

Let's assume that the output from the `homie/homey-topic/lumiere-pierre/onoff` MQTT node will be a string "true" or "false" (not Boolean `true` of `false`).

In your switch node you currently are testing for a Boolean value, so you need to change it to expect a string value, like;  
 ![switch](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/f/8/f84436d0ed7fb87db559dadec9c2d1f78e2b06bc.jpeg)

Also as you are specifying the MQTT topic in the switch node, there's no need to also set it in the MQTT node.

Also you should have the switch node configured with pass through disabled and to show the state of the input, otherwise you will get an mqtt loop.
