SHT7x not work after update

[wangine]

Mycodo Issue Report:

• Specific Mycodo Version:4,.0.26

Problem Description

After last update the SHT75 sensor stop working.

Errors

No any error when i try to activate/ desactivate the sensor , but sensor not respond , I try to change the sensor with SHT71 , same result . I try to force reinstall and the same problem . I think is update problem because the sensor is working on the same configuration on other PI board but that PI wasn't update 3 months ago. I didn't try a new fresh install , my computer broken ,and i didn't has time to fix it.

@wangine I wouldn't bother reinstalling anything just yet. Would you be able to run the sensor directly using the SHT1x7xSensor class? I'd love to see more info about what's happening but I don't have that sensor to work with. So with your sensor, here is how I would approach doing that:

1. Move into the Mycodo/mycodo folder. Assuming that the Mycodo folder is in your home directory: cd ~/Mycodo/mycodo
2. Start a python console and enter the following lines:

   
   from sensors.sht1x_7x import SHT1x7xSensor
   from time import sleep

Important: you must use your input pin number, clock pin number, and voltage value

In this example I'm using input pin 4, clock pin 99 (because I have no idea), and a voltage of '5.0'

sensor = SHT1x7xSensor(pin=4, clock_pin=99, voltage='5.0')

take reading with a 2 second sleep in between

for result in sensor: print("Dew Point".format(result.dew_point)) print("humidity".format(result.humidity)) print("temperature".format(result.temperature)) print("-" * 10) # prints a line to visually separate out each loop sleep(2)

Let me know if you run into any issues with the code above.  You'll need to put in the correct pin numbers.  For instance I have no idea what your clock pin is or your voltage.  A good idea is to use the same values you have in your configuration so that we are testing the correct setup.

To start the python console you can just type python and hit enter

I just pushed an update (commit 6477798) that may fix this issue. See if it works after updating your system.

Thank you Kyle , it's working now. The sensor work normal , have a great day.

@wangine, Great!

@etiology, sorry to jump in with that commit before getting a chance to see the console output, but I saw what I thought would be causing the error and wanted to commit it before I forgot about it.

@kizniche damn you're fast! Good job pushing the fix. I've never played with these sensors before so if you have the fix I'd say ship it.

@etiology, I've never used an SHT sensor. @wangine has been the one who's helped to bring support for the two SHT classes to Mycodo. In this case, I just happened to notice uses of self.temperature and self.humidity when they haven't been set yet :)
