Hello!
PLEASE HELP… I’M GETTING DESPERATE!
I’ve researched the documentation on the product page and have sought assistance on your forum months ago to no avail. I’m really feeling at a dead end here and really would appreciate any assistance you can provide!
I’m new here and attempting to build the propane poofer which utilizes the Thing Dev built-in WIFI capabilities to broadcast a wifi network & host web page interface to control the poofer. I uploaded the provided sketch to the ThingDev which was wired up with the other components as in the tutorial. The ThingDev broadcasts its WIFI SSID while still connected to my computer’s USB for power and I’m able to connect to it with my phone and navigate to the the poofer control webpage on my phone. All the relays, switches and solenoids respond appropriately to clicks as expected. BUT… when i disconnect the USB power to make the ThingDev run soley on the 12V SLA battery the unit powers up (confirmed by illuminated onboard LED) but it doesn’t broadcast its wifi network SSID.
Wondering what is going wrong. The fact that it works as advertised when hooked up to USB makes me think that the ThingDev is functioning properly makes me think it has something to do the VIN after the regulator. Does this need to be powered via USB? I followed the tutorial to a ‘T’
I am following this tutorial on the esp8266 powered propane poofer:

Any help is super appreciated!
Is the battery wired to the upper terminal in this photo (next to power switch)? https://cdn.sparkfun.com/assets/learn_t … 66-top.jpg
Share a couple photos - also maybe try the default web server example https://learn.sparkfun.com/tutorials/es … web-server , get that working via battery-power, and then circle back to the propane poofer after ensuring it’s working correctly
The hookup guide (linked) also notes to use ‘nodemcu’ reset mode, which might have a effect?
Thanks for the reply!
The battery is not wired to the terminals between the switch and the usb-micro jack. It is wired to the VIN & GND pin outs below the switch as in the tutorial. (See pics) Is this the problem?
I will try the default web server example.
Where does the hookup guide note to use ‘nodemcu’ reset mode? I do not see that.
Are these boards supposed to be able to permanently store and automatically run the sketch that has been uploaded to them even after power has been interrupted and restored? I figured this was the case but in practice mine is not doing this.
I have been playing around with the “ESP8266 Powered Propane Poofer” tutorial on the Sparkfun website. The the uploaded sketch works flawlessly right after being uploaded IF power is maintained to the ThingDev board. If I turn the board off or unplug it’s power source and then restore power, the ThingDev does not run the sketch automatically. I’ve confirmed this is the case with the “ESP8266 Powered Propane Poofer” sketch as well as the simple “Blink” example sketch. This is baffling.
What am I missing? Can anyone tell me if there is a way for the board to boot and execute the script AFTER an interruption of power?
Thank you!
Please do not post the same question in multiple different places in the forum.
My apologies. I posted in another topic because My problem now seems to be more specifically related to the thingDev itself and not a wifi issue. It was an attempt at targeting a more appropriate audience .
Cheers
