Dave , I think that shot was probably taken when the flow needed to be deployed. I can assure you that there are no blue dots on there now.

DynamicDave is the winner. It wasn't the little blue dots he was concerned about, it was the lack of green in the button at the right end of the debug node. When I clicked in there everything came to life. I just couldn't get that idea out of my head so I investigated that node and that was it.

 ![Debug](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/8/e83368b785b6afd15962dafd7df48723099c4a39.png)

Now , I plan to dig the hole deeper by installing the security credentials.

Three cheers to "DYNAMICDAVE" and to all the others who hung in there with me. I just hope I can return favor some day.

Can i suggest before you go any further you maybe look at moving to a standardised firmware that everyone knows on your Sonoff devices - i would recommend Tasmota, others like ESPEasy or ESPHome - whatever one you use is something that some of us are familiar with and can help to troubleshoot - some random firmware on the internet that appears to be behind a paywall is not something that too many of us will put time into trying to solve (and you can see how long it took to find a solution with your continually referring back to the tutorial when trying to rebuilld

I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.

Two great suggestions. I have cut a lot of material out of this thread for reference.  
Thanks again to both of you
