In part one we looked at re-programming pretty much any ESP8266 based board including the ultra low cost SONOFF Mains controller. here:- https://youtu.be/ixuXI4lQL1U

Now we will expand the system to include a central (Home Based) controller running MQTT and Node Red. This will allow all sorts of workflows to be configured and also select information to be shared out onto the Internet if wanted or needed.

Primarily here we will use it to provide initialization information to the nodes to set time, dusk and Dawn etc. it is an easy thing to also add other configuration info if needed but not included in this post.

Node Red can be found here :- http://nodered.org/
various MQTT implementations here :- https://www.oasis-open.org/committees...
