Re: Web enabled thermostat project

Hi everyone! I do apologize for not being more active on this project. Between work and family there is little extra time. I have finally invested in a 3D printer and am awaiting delivery. So in the meantime I've been working on a wall mount. It's available on Thingiverse but us as of yet untested. ...

Bonsoir, I have adapted your code for my regulation (relay is replaced by a servo motor that drive the air trap of my DDG heater) one problem is remaining, the temp setup performed by the web interface doesbn't work ... i have'nt modifiied your code except the path .... j'ai adapté vos source pour ...

Re: Web enabled thermostat project

The only thing I can think of off hand is permissions. You need to ensure that the user (mine is www-data) has read and write access to the thermostat file. I had some issue with this when I was first setting it up. Have a peek and let me know what the thermostat file permissions are set to.

What relays did you use for this?

Thanks,

Nick
I found mine on ebay. I used a 5volt relay board for an arduino.

Or you can also find them at sainsmart.com.

Hi, I have no idea about electronics. But i am very interested in sensing my sump pump failure. So is there a way to get digram of electrical circuit? Or something that shows how to wire everything. This was actually my next project for the Pi. I should be able to get some code together for you. Ma...

Hi Guys, I do apologize for not getting back to many of your requests sooner. I'm pretty busy with work and family, so not much extra time to spend revising the thermostat. I have had an enormous number of requests for all the web code etc. So here it is! https://www.dropbox.com/s/krq6z6hw5nz9f9o/th...

Re: Web enabled thermostat project

You can find a relay module at sainsmart.com. They're really reasonably priced and worked easily with the Pi's 5v power. They also have data sheets on sainsmart.com that tell you the current draw for each channel individually and when all are on. If you are only using 1 to 4 relays I think the Pi wo...

Re: Web enabled thermostat project

You should check the crc of the ds1820 sensor. I just finish to hook up 5 sensors on my pond heater system and I found out that sometimes sensors gives bad results. When I looked at the returned data, I found out that every time the temperature is wrong , the crc is also not ok. (data return is all...

Paul, Here is some sample code from my thermostat web interface. This takes the temperature from the drop down form and saves it to a thermostat file. The python module then calls for this file to check for the desired set temperature. <?php if(isset($_POST["settemp"])) { $settemp = $_POST["settemp"...
