Raspberry Pi, Linux, Python

I forgot. Dumb questions are not allowed :notworthy:

Seems over whelming in the number of options to display remote data

Roll your own stuff, VNC, web streaming, web servers, Cacti, Thing Speak, XIVELY....

I wish it was still winter, 3 feet of snow and 20 below zero F. Then maybe I could look at all the options and decide which one to go with. :banghead:

BTW are there more options like Thing Speak and XIVELY? :think:

Hi Bob,

Are you aware of the Network Weathermap (http://www.network-weathermap.com/) plugin for Cacti? This is very useful for displaying/diagraming the data on Cacti. Takes a while to learn and to customise, but it is very powerful if used right.

Just another option in the mix! :thumbright:

Cheers,

Mon

I removed the raspberry pi and replaced it with an Electric Imp.

For simple temp monitoring I like the imp more than the pi

- no power needed, easily runs off a 9v battery (should run months at 15 min update intervals)
- only need an imp, cap, thermistor and battery
- xively graph and dev pages give me everything I need

Thanks Jayendra :thumbright:

Sorry to raise a zombie thread from the dead, but I wanted to share a rather simple setup I've adapted from various online sources. I have a Raspberry Pi with three DS18B20 waterproof probes with 1 m leads. The Pi has a small wifi dongle and is set up to run headless, i.e. I log into it via remote desktop to control/program it. It runs a fairly simple Python script that reads the three probes every 10 minutes (inside greenhouse, outside greenhouse, FT water) and here's the great bit: uploads to a Google Docs spreadsheet. I have various plots, averages, etc. on the spreadsheet that are automatically updated and can access it from anywhere. Fairly simple, now that the wrinkles are worked out (mostly due to my ignorance of Linux, Python, etc.).

This is gonna do eveything you want

Neat, but significantly more expensive. Also, most people messing with the Pi (and aquaponics generally) enjoy the DIY aspect.

Still, thanks for pointing us toward it. When is it supposed to be available?

newagefarmers

i'm not sure sadly... I've waited for 3 months since i entered my email. I agree the DIY aspect is for sure more fun. But the amount of information/add on sensors are probably worth the price compared to having to buy all the parts, build it from scratch, and then troubleshooting a raspberry pi that may not be able to sense all these readings.

While looking for an introduction to Python, yesterday I ran across this link:

https://www.udacity.com/course/ud036
The course is free (kinda sorta) and self paced. My kind of education. :blob:

While the programming projects look kinda boring the last program might have some possibilities.

Instead of making a program to show one's favorite movie trailers (U- Tubes) why not build something to recall favorite AP videos? Videos from the forum and or the internet?

What do you :think:

BTW can the BYAP web page/forum store a computer program? one that calls up U-Tubes?

If the site can do that maybe an AP video data base program might make a good AP community project?

Just thinking :think:

Hi Jake are you able to share your code for the pi that uploads to google docs?

+1 to see some code please

Jake

I basically adapted the code from here: http://www.danielhansen.net/2013/03/ras ... using.html

I made a few messy changes, but that code only exists on the Pi, so I'll have to wait till I get home to grab it (since I can't figure out how to get Remote Desktop to work from anywhere but behind the same Wifi router).

JimV

Another +1 for the code, if possible!
