Hi, 
So I’m enjoying the Home Automation course, which I must say is very well done. 
Unfortunately I’m struggling with getting a Sonoff switching from the Node Red dashboard. A Debug window shows that the output text string is being published as “on/off” but the relay doesn’t switch. 

  • My RPI has a brand new image of Rasbian Stretch (no security) 
  • Node Red works fine in all other lessons
  • The Arduino sketch seems to load no problem (modified with SSID/Pwd/MQTT IP Address
  • The same Sonoff flashed with Tasmota works fine (from the web server)
  • A D1 Mini with the “Hello World” sketch loaded also failed to deliver anything to the Node Red dashboard. 
  • Following Dr Zzs Tutorial I tried to use Tasmota via Home Assistant with similar none functioning dashboar

So Im at a loss. The hardware has proven to be functional (tried a different unit for the sake of my sanity)
Any ideas?? Or advice on troubleshooting tools? 
Warm regards 
Paul

OK. After going over every piece of information the solution was a missing underscore in the SSID!!!!!

I’m glad it’s working and I know how frustrating that can be! I’ve misspelled the SSID and password multiple times.
I’ll mark your thread as “resolved”. If you need further help just let me know.
Regards,
Rui
