airpi's Issues

Calibration functions with `findval()` in them

DEBUG:main: ERROR: Exception during output: global name 'findVal' is not defined

Metadata doesn't include operator

The 'metadata' output with print or csv currently always outputs a dummy name. It does not yet use the setting in settings.cfg.

Hangs on "INFO: Doing initialising runs for 15 seconds."

When I run airpictl.sh normal the process seems to freeze at "INFO: Doing initialising runs for 15 seconds."

Have left it for several minutes. No change. Won't respond to ctrl+c.

New Raspberry Pi 2. AirPi 1.4 (previously working on an old Pi).

Fresh install of Jessie Lite. Have updated and rebooted.

Full output is:

HTTP output plugin causes RPi crash after long time periods

Enabling the HTTP output plugin has been shown to cause the Raspberry Pi to crash after running for any length of time. There are no error messages or debug messages displayed. Cause is currently unknown.

BMP085 - amending temperature for accurate results

Hi

My BMP085 reads about 3 degrees C higher than the real temperature

What line do I need to add to supports.cfg to minus 3 degrees off the result?

Thanks

HTML output - not all graphs update correctly

Using HTML output - all working fine and showing correct readings/headings, but not all of the graphs seem to update correctly

i.e. AirPi been running 3 hours, top graph for Temperature-BMP is showing full 3 hours in the graph, but most of the others just showing an hour or less and not updating to show full period that AirPi has been sampling

No configuration instructions

When I first ran the software, it popped up with this error message:

Error: Check wiring for the TGS2600 measurement, no voltage detected on ADC input 1

Looks like it wasn't correctly configured for my sensors.

HTTP Server Errors (Similar to #19)

After tireless hours of running into compatibility issues, I've made it to somewhat of a point where I can take readings from my sensors. But when I try and view the via the built-in HTTP server I run into an error:

Exception happened during processing of request from ('192.168.1.237', 46793) Traceback (most recent call last): File "/usr/lib/python2.7/SocketServer.py", line 290, in _handle_request_nobloc k self.process_request(request, client_address) File "/usr/lib/python2.7/SocketServer.py", line 318, in process_request self.finish_request(request, client_address) File "/usr/lib/python2.7/SocketServer.py", line 331, in finish_request self.RequestHandlerClass(request, client_address, self) File "/usr/lib/python2.7/SocketServer.py", line 652, in __init__ self.handle() File "/usr/lib/python2.7/BaseHTTPServer.py", line 340, in handle self.handle_one_request() File "/usr/lib/python2.7/BaseHTTPServer.py", line 328, in handle_one_request method() File "/home/pi/AirPi/outputs/http.py", line 323, in do_GET page = replace(page, "$time$", self.server.httpoutput.lastUpdate) AttributeError: 'HTTP' object has no attribute 'lastUpdate'

This occurs when I initially try to load the webpage (which I had previously enabled in~AirPi/cfg/settings.cfg). I haven't the slightest clue as to what I can do so any help would be much appreciated.

ThingSpeak and Xively plugins not working

ThingSpeak and Xively output plugins are not currently working when enabled in outputs.cfg. Reasons unclear as yet.

HTTP Plugin: Several Errors

Hey there! I'm currently setting up my own AirPi and I'm pretty happy about this fork for having done all the things I'd need to implement myself ;) Thank you!

However, trying to use the http plugin results in serveral errors. They appear in the dev and master branches, my current setup is using the dev branch:

ERROR:   Failed to import plugin HTTP: global name 'calibration' is not defined

I solved that one myself by adding a simple import calibration at the start of the file. With that, the http plugin loads, but trying to access the site gives me the following error:

This happens no matter if the sampling has actually started or not. I fixed it by replacing self.server.httpoutput.lastUpdate with the current time, but this yields the following error:

    for i in self.server.httpoutput.data:

----------------------------------------

I'm assuming that the sample data isn't send to the http output module, but since my understanding of the projects code (and, well, python) is very shallow, I can't fix this on my own. Any ideas?

I'll maybe try an older commit until this is fixed.

Update: Reverting to commit/version 1.0 didn't fix this :/ (it did fix the import however)

GPS print.py output exception

When trying to print to console via print.py with GPS enabled, there is no GPS output, no '=' delimiter line between readings, and in the airpi.log file I see the following:

2016-09-25 17:01:05,689 - __main__ - DEBUG -  ERROR:   Exception during output: Unknown format code 'f' for object of type 'str'

The breakage seems to have happened In the commit by Haydn Williams on Oct 15, 2014 - Lots of pylint improvements.

This part of the commit in format_output_gps() broke GPS output:

 100       -        return str(prop.ljust(17) + ": " + str("{0:.2f}".format(value)).rjust(10) + " " + unit) 
      147  +        value = str(prop.ljust(17)) + ": "
      148  +        value += str("{0:.2f}".format(value).rjust(10) + " " + unit) 

Note that value is passed in as an argument then immediately overwritten and assigned a value that is a string. When it is then appended to, the attempt to format what is now a string as a float causes the exception.

GPS output works by just changing back with an ljust(18) to match the other outputs:

return str(prop.ljust(18)) + ": " + str("{0:.2f}".format(value).rjust(10) + " " + unit)

Raingauge error

TypeError: buckettip() takes exactly 1 argument (2 given)

"Sample frequency too fast" warning appears at wrong time

The warning designed to highlight when the sample frequency is too short sometimes appears even when the frequency is sufficiently long (e.g. sample every minute and average every ten minutes).

Calibration and conversion of raw sensor values to real-world units

I was wondering if there were plans to update the calibration code to convert the readings to more human-readable units (ppm, dB, etc.) instead of the raw ohms or millivolts? Mainly for Nitrogen Dioxide, Carbon Monoxide, Volume, etc.?

I was happy to see some of the calibration formulas in /cfg/supports.cfg but they are all commented out and don't seem to convert units. Thanks!

git not installed in install.sh

Hi,
Just use your install procedure on a fresh RPI and I noticed that git is not install by the install.sh while it is required further in the install script.
Maybe an apt-get install git can be inserted in that script ?
Regards.
Alexandre

Averaging function causes "Sample frequency too fast" to display.

Enabling the averaging function can cause the "Sample frequency too fast" warning message to display, even if the sample frequency is not too fast.

Note that the values output by the averaging function are correct; it is only the display of the warning message which is incorrect.

Probably related to issue #10.

error with ubidots plugin

get following error with it enabled:-

Missing config section for plugin Ubidot.
ERROR: Failed to import plugin Ubidots

HTTP plots show time in UTC, not in local time

The plots in the HTTP output plugin show the time axis in UTC, not in local time.
Can easily be fixed by correcting for the local timezone offset:
Line 206 in http.py (in recordData function):
Change 't[0] = time.time()' to 't[0] = time.time() - time.timezone'

problem with rrdoutput module

Thanks for the project, very very nice work.

Previously I used the csvout it works well. For the past few days I'm trying to use rrdoutput but without success.

There were some issue like problem with lack of calibration module and graph printing section (i throw out it from rrdoutput.py) and I assume it should help. But I got the following error in debug mode.

The installation is clean, sensors are working, tested outputs http, cvs, print works like a charm. Rrdoutput no :/
Rrd file created manually, path is correct and present in config file. Have no idea were cloud be the problem.

commit fce8f757f9c6b549be7c8e46d69869584de3c69d
Author: Haydn Williams <[email protected]>
Date:   Wed Nov 11 20:53:45 2015 +0000
Change: Update release notes in README.md. Add line re: GPS setup.

Did you met that kind of issue?

What to do about ever-increasing sample frequency?

Sample frequency increases by 0.01 seconds per sample, so at high frequency it will start to deviate after running for some time. Professional-grade scientific gear skips a sample or just resets the clock every 24-hours - do we just mimic that behaviour?

GPS and xively

If GPS is enabled, it´s not possible to upload to Xively ?

Rain Gauge convert the Bucket Tips to mm per hour

I was trying to implement it myself into the support.cfg but I have to admit I have failed...
Since 1 tip equals to 0.2794mm the equation should be something like:
Total of the tips times 0.2794mm in 3600 seconds and reset, but since I am an absolute Python I have no idea whatsoever on how to implement it...

func_Nitrogen_Dioxide = (0.0014*(x/142686.5672))+0.2857

Any other one and I get this error:
