After about 24 hours the airpi.py script seems to stop generating logs.

I am not sure if you still are using the AirPi?!

I try to add a new sensor based on your template (SHT31 temperature and humidity sensor) with no luck so far.

Could you please give some advice?

`#!/usr/bin/python

import sensor
import time
import smbus

class SHT31(sensor.Sensor):
requiredData = []
optionalData = []

def __init__(self,data):
    """
    Initialisation.
    Any initialisation code goes here.
    """
    self.readingtype = "temperature"
    self.sensorname = "SHT31"
    self.valname = "Temperature"
    self.valunit = "Degrees Celsius"
    self.valsymbol = "C"
    self.description = "SHT31 Sensor for Temperature and Humidity."
    return

def getval(self):
    try:
        bus = smbus.SMBus(1)
        bus.write_i2c_block_data(0x44, 0x2C, [0x06])
        time.sleep(0.5)
        data = bus.read_i2c_block_data(0x44, 0x00, 6)
        ctemp = data[0] * 256 + data[1]
        temp = -45 + (175 * ctemp / 65535.0)
    except TypeError as terr:
        pass
    return temp`

So far, the name: tag should be the name of the stream (eg, Temp), and the raw tag should mean it isn't displayed on the site - raw tag doesn't do anything at the moment.

As seen on

• https://github.com/tomhartley/AirPi/blob/master/airpi.py#L48
• https://github.com/tomhartley/AirPi/blob/master/airpi.py#L116

Basically, that's just the way Python works. There's a very details explanation at https://stackoverflow.com/questions/2724260/why-does-pythons-import-require-fromlist

Personally, I'd use fromlist=['magic'] ;-)

Values of self.SPIMISO and self.SPIMOSI in sensors/mcp3008.py are wrongly coded.
This is how it is:
self.SPIMOSI = 23
self.SPIMISO = 24
And this is how i've done to work well in my raspi v1 b:
self.SPIMOSI = 24
self.SPIMISO = 23

Things which should probably be in the config file:

• LCD on/off
• ADC pins for analogue sensors
• DHT22 pin
• I2C bus number
• enabled/disabled state of all sensors
• ADC connections from Pi GPIO
• API key for Cosm
• Feed ID for Cosm
• Watchdog enabled/disabled
• Restarting Internet enabled/disabled
• Pull up resistor sizes for MiCS sensors
• Base resistance for MiCS sensors

Not sure what format it should be in yet.

The link provided in the website www.airpi.es for circuit diagram http://www.circuits.io/circuits/1946/schematic isn't working. Please provide a new link or the file containing circuit diagram.

Ideally, should have configurable duration for the window, as well as ability to control which sensors you want it for. Most probably the Air Quality ones, but maybe also the UV sensor and others. Potentially upload the raw values to Cosm as well.

Instructions missing the command

sudo pip install requests

For running the latest version.

Hi,
I've just assembled my board I got from the indie campaign and I've noticed that the software is still reporting UV sensor and has no value for microphone. Also, the CO reading seems to be stuck on 40ppm - is this a also a software issue or is something wrong with the sensor?

Dear all, unfortunately i have been waiting for too long on a Tindie order for the Board, so i was wondering if you would be kind enough to share the Eagle file of the latest board (0.4+) so i can have some printed myself on Seeedstudio.
The version you have shared now is an old one, and as i already have a case for it, i would really appreciate having the latest design.

Thank you in advance,

Luka

Hello,

i made a fresh install with RaspberryPi B+ and my AirPi PCB 1.4 and get the following error. On Debian Jessie it runs great.
All configs checkt, no sensor problem

Greetings from Bavaria

Dear all, first of thank you so much for this project, i just got and built mine and im loving it!!
I have an issue though i hope someone here can helpo me fix.

The Pressure and Temperature readings are not being calculated, they stay stuck to some value since the first time i got it running.
I triple checked the soldering and its all fine.
I also get around 15-20 lines of : Error Accessing 0x77: Check your I2C address, every time after uploading succesfully, but that is set just fine in the cfg, as its working for the other sensors, and the i2cdetect confirms i got a Rev2 board.
The bmp085Backend.py does have a line reading i2c = none near the beginning, but im assuming thats some sort of initialization right ? (sorry im not that good with Python yet. .)

You can check the live feed here, and you will notice pressure and temperature are not working> https://xively.com/feeds/1547432953

Im about to order a new BMP085 as i have to assume this one is busted, but if anyone had encountered this error, or knows what might be causing this please let me know, i would really like to finish this asap so i can move to the projects other parts ..

Thank you in advance,

Luka

I find this project very useful and I am developing this further however I need the LICENSE so I can give credit.
Thanks!

Hi,
I am having the following errors appear when i run airpi.py, and can not fiigure out why:

Error: Did not import sensor plugin BMP085-temp
Traceback (most recent call last):
     File "airpi.py", line 88, in <module>
         raise e
NameError: global name 'requiredData' is not defined

Many thanks,
Jonathan

I'm trying to figure out a way to use this code without uploading it to the internet, probably by way of a MySQL database controlled by Python. Does anyone know the best way to do this?
