What is the chances of posted the detailed wiring and parts list? This sounds excellent.
Thansk

Ok, spent half the day trying to figure out what I was doing wrong and all I had to do was read the forum. The radios I purchase were junk. Not one of the 10 worked. Had everything placed on a board figured my workmanship was a little off or something. The radio was last to be checked.
WOOOOOOWWWWO

Thanks Everyone this post saved me a lot more time.

Yes the file ending in .ino is missing as you can see by your post above.

Did you get this working and if so can you share?

Thanks, that worked.

I figured why wait, this has the temp, hum and 2 relays working not problem. One relay controls my fan for my AV and the other controls my doorbell for my HTD Lync system.

Hi

Thank you for your reply and I understand that, if you look at the code you will see that pin 3 isn't named/defined in the coed. Unless I am missing something

Thanks

Hi,

I see in the pictures of the connection that the soil sensor is attached to 3.3V, GND and D3 but I can't see where D3 is named. How do you obtain a read from D3 if it isn't named in the code?

Hi All,

I am using the Pete B. Push button concept to turn my kettle on and start boiling and need a little help. When I press the button it will not send the code to turn the kettle on. I used the same wire diagram as Petes ground sample. It is a ground and a simple touch button as I can touch the wires tomorrow to simulate a button and confirmed it’s ground. Has anyone complete code for this and if so can I use it?
Thanks
Tim

Hit post to quick sorry, my plan is to have 4 probes each on a timer. Press the button and put on the steak have Alexa tell you to flip after 2 minutes for rare and the another 2 minutes and she will tell you done with a temp of 125f.....

@alowhum all help greatly appreciated

Hi All,

I am developing a BBQ Sensor that will set a timer for each probe and tell me when to turn it over depending on what I am cooking (i.e 135F = rare, 2 minutes side one and 2 minutes side 2). Any idea if anyone has developed something like this already? I found the smoker files but I am BBQ fellow not a smoker.....

Thanks

Any ideas on how to start? Maybe we can all help.

I figured why wait, this has the temp, hum and 2 relays working not problem. One relay controls my fan for my AV and the other controls my doorbell for my HTD Lync system.

HI

I did get it to work and will post the sketch later today after work. I have it working on the ESP8266 and Arduino.

HI Everyone,

I noticed that I couldn't find a relay working with ESP8266MOD, I was messing with it over the last few days and figured out that the following sketch works. The big fix was in the sketch you use pin 0 for the relay and actually attach it to pin 3. This works great with WEMOS ESP8266.
