It is like nothing works

by justterry on Thu Feb 11, 2016 9:25 pm

I am very frustrated at adafruit io

I have tried several tutorials for both the raspberry pi and the huzzah and have had no success.
latest is the huzzah esp

I set it up,
https://learn.adafruit.com/adafruit-huz ... 6-breakout
did the test and it said it was working I then tried the adafruit io button sketch.
I copied the sketch from the git hub and this is what I get.

WiFi connected
IP address:
Connecting to Adafruit IO... Connection failed
Retrying connection...
Connection failed
Retrying connection...

for the last several weeks I have repeatedly struck out
if I am doing something wrong please let me know.

Looks like u just posted this. If so it does look like the service is currently down. And ironically so is IFTTT. Had me scratching my head for a bit as well. Give it a while should come back up.

I am glad someone else is also having connection issues. I thought I had done something wrong in my code while I was adding to it.

Seems I to have had no luck following any online instructions to connect to adafruit io, many of the adafruit instructions will not compile and are fairly old so it seems since I can get none to connect, but if i run the Adafruit cc3k example for adafruit io it connects and publishes just fine. so Adafruit isnt down its the coding of these instruction pages is outdated, I am a newbie so I could be wrong but no luck with any of them, except the example included in the adafruit mqtt lib.

mqtt is the best way to connect!
the cc3000 is a really annoying and difficult module to use, if you have an esp8266 or winc1500 or ethernet those will work better. we're going to discontinue the cc3000, its too hard to use.

I had a bigger issue with esp8266 witch I fried yes did the plug in wrong volatage, saw a post somewhere said the cc3k was easier lol go figure, just got it and its connected having no prob with the module, my issue is the coding of the connection and publish, and older instructables that wont compile right got it compiled but it drops connection, right now im craming mqtt_cc3k in my head as i am sure if find a way to change from pubsub to this in my sketch it should work flawless on connection, I dont mind harder to work with I just learn more :)

Well I am so happy to say that it all seems to be working now. (at least with the huzzah esp module and I have to say that I understand the arduino IDE much better than the whole NODE.js I was using on the Raspberry pi. I have the temperature and humidity reading off the DHT22 and showing up on Adafruit IO. next I will have to add a power supply and try moving it to different parts of the house. Right now I am powering it from the Console Cable I used to program it. This is all part of my hopes of building a Smart house. and now that I have some success I guess I really have to decide what the whole Idea of a smart house means.

It has to be more than just turning a few lights on and off, and knowing when doors are open or closed, and who opened the door. Still I am pretty happy with the beginning of things.

Thats cool, mine is arduino with dht 22 and a light sensor, the beginnings of a green house total control, playing with the code in the example I now have mine sending data to the tree feeds as well, but currently its incremental numbers rather tha temp and humidy but so much closer... mine is a huzza cc3000, now just working out the publish lines since I believe theres something in there sending the wrong values.

Here is what I have that is working with only a couple degrees F difference between it and my Temp humidity box I picked up at home depot

pin 1 of DHT22 to 3.3v
pin2 of DHT22 to pin 5 on huzzah esp
10 k resistor between pin 1 and pin 2 of DHT22
pin 4 of DHT22 to Ground of huzzah esp

I have it updating every 5 seconds to make it easy for me to see what is going on.as well as printing the values to the serial port for debugging. I will eventually reset the time to something a little more realistic (every 5 minutes) and get rid of the debugging serial printing.

I agree. I've been experimenting with WIFI robots and the CC3000 is a POS. It connects for 30 seconds then disconnects, even if the project code has watchdogs to prevent this and reconnect. Not impressed so far! I've spend 100s of dollars on this stuff and haven't had much success yet. Good thing it's an enjoyable hobby and not work related. Reading that the CC3000 is about to be discontinued is annoying because I just bought two of them. Can I return them do you think?

you can post a new thread but im going to lock this topic because we have a full forum and it never works out to have 5 people in one thread with "it doesnt work, now it doesnt, but it doesnt for me!" replies! :) the OP got it working, so this thread is resolved
