Sample code for EZControl and Lelylan - it works!

[oto...@gmail.com]

Guys,
This code works for me.
I connect through a home WiFi router with no problems.
Any changes I make with the EZControl are relected on Lelylan and any Lelylan changes come back to the EZControl.
I had to use Arduino IDE 1.0.6 to get it to recognize the MQTT library.
Note the changes in the interrupt and enable constants for the CC3000.
I use a simple read from the serial monitor either n or f - oN or ofF - gettit!

I did not actually test the relay was turning on and off a light but there is no reason it will not work once you get your wiring correct.
Remember to be careful working with mains voltages.

It seems we lost a ">" in the process of posting this!
It should be if (Serial.available() > 0)

[marti...@gmail.com]

I can confirm that this sketch works.   We need to make this available for people to use.

We're closing some meetings and then we'll focus on creating the best documentation.
It should be ready for tomorrow.

Hi everyone, 

we've been working on making the final documentation as complete as we could to make your EZControl work with Lelylan.

Here the link: http://lelylan.github.io/lab-projects/ezcontrol-light

A special thanks to Mick (aka otoolo) which was great enough to take the time to play with the EZ and solve the main issues. Thanks.

Everything is not working. This means you can control your EZ from Lelylan and you can reflect the physical changes to the dashboard. We also added info about the PINS: Relay on port 7 and temperature sensor on port A3. The Arduino IDE board must be the version >~ 1.0.6.

I you guys can test it out, issue new problems, we can improve even more the documentation. 
The documentation is on Github, so feel free to send us a pull request for any improvement.

All the best

[Lelylan Support]

Sorry :%s/not/now (Everything is now working)

I can not get past the:

"[CC3000] Setting DHCP"

It just hangs there and nothing happens.  Any suggestions on what could be causing this?  (using the EZControl.it board).

Some additional info:

• My router recognizes that a new device has connected, and an IP has been assigned.  I just don't know what the line:   while (!cc3000.checkDHCP())  is waiting to receive, and how I can check the status of the request.
• Not always, but most times, after about 1 minute the LED will light up, but I can not control it from the Lelylan app.  I can only control it from the physical push-button.  So obviously there doesn't seem to be a connection between the board and the app.

Note:  If I switch and use an Ethernet Shield (with the appropriate code) I have no issues, but I really want the EZControl.IT board to work.

Thank you,
Rich

Hi Rich, 

were you able to find a solution?
