At the section at or near page 112,  “Creating your Flow”. The text refers to mqttt out but the graphic shows “Edit mqtt in node”. It appears that later the text refers mqttt in but the graphic shows “Edit mqtt out node”.

I am really struggling with the this in/out topic . Is that a misprint or I am reading more into it than it is?

I have been able to get through a good share of the course but I am having trouble with my current project. I am trying to construct a motion sensor connected to an esp8266. This device will be used to operate a sonoff basic device that I have already flashed per your instructions. I have several of them flashed and working from the dashboard with manual switches. But I am having trouble deciding the TOPIC names for the sensor. I have named the switches all sonoff with progressing serial numbers. Should the sensor unit be named to match the sonoff switch that I intend to control?

On another subject, I was never was able to get the 433mhz system to work. Everything worked as per the course right up to the final step. I set up a second independent receiver to verify that the signals were being transmitted. All the codes appeared to be correct but the devices did not work. The devices work fine with the remote transmitter that was used as the source of the codes. So I intend to rework that segment of the course. But my primary focus is going to be on the sonoff  and their control.

Any further information appreciated

Hello! I apologize for the trouble, because that’s a typo on our end (it will be fixed in the next course update). The text is incorrect in page 112 and page 113, please follow the images.
Here’s the corrected text:

• Page 112: Double-click the mqttt in node to edit its settings. Select the localhost option and type outTopic.
• Page 113: Double-click the mqttt out node to edit its settings. Select the localhost option and type inTopic.

Is the MQTT message being triggered in to publish the 433MHz signals? I’m not sure what’s missing, because it looks like you’re doing everything right, so it should work for you

Thanks for the help. I am going to completely redo the part of the course involving the 433mhz devices. I am sure that I have made an error somewhere. I just seem to be having a tough time with the topic business.   My main goal now is to get a esp8266/motion sensor to control one of the sonoff devices..

Just double-check that those signals are actually being triggered with the MQTT message. Otherwise, it’s very hard to know for sure if what’s missing
