TSL2561 not working

[cohe4ko]

Mycodo Issue Report:

• Specific Mycodo Version: 5.0.13

Problem Description

I have not original (not Adafruit) tsl2561 with 0x23 i2c address. I can't set this address in setting. Even when I tried to hardcode this address in tsl2561.py - the device doesn't work.

[kizniche]

Have you been able to run any code to get it working (non-Mycodo)?

[kizniche]

My TSL2561 sensor is working with Mycodo 5.0.13, btw

[cohe4ko]

This code works for me:

import smbus
bus = smbus.SMBus(1)
data = bus.read_i2c_block_data(0x23,0x20) # 0x23- i2c addres, 0x20 - ONE_TIME_HIGH_RES_MODE_1
lux = ((data[1] + (256 * data[0])) / 1.2)
print (lux)

[kizniche]

Even when I tried to hardcode this address in tsl2561.py

How were you doing this? Can you paste your code?

[cohe4ko]

I found it here: https://github.com/ControlEverythingCommunity/TSL2561/blob/master/Python/TSL2561.py and then here: http://www.raspberrypi-spy.co.uk/2015/03/bh1750fvi-i2c-digital-light-intensity-sensor/ As I understand it's some modification.

[cohe4ko]

Oh I found what the problem: there is two different sensors: TLS2561 and BH1750. I bought BH1750 with a marking of TLS2561. China is China :)

[kizniche]

Ah. That's easy then. I can just add the BH1750 to Mycodo.

[cohe4ko]

That's would be great! :)

[kizniche]

Can you test this code? It appears more feature-rich ;)

Yes, It works. but you need to make some way to chose sensitivity.

Sensitivity: 69 Low Res Light Level : 3.33 lx HighRes Light Level : 0.00 lx HighRes2 Light Level : 0.00 lx

Sensitivity: 79 Low Res Light Level : 5.82 lx HighRes Light Level : 0.00 lx HighRes2 Light Level : 0.00 lx

Sensitivity: 89 Low Res Light Level : 5.17 lx HighRes Light Level : 0.00 lx HighRes2 Light Level : 0.00 lx

Sensitivity: 99 Low Res Light Level : 4.65 lx HighRes Light Level : 0.00 lx HighRes2 Light Level : 0.00 lx

Sensitivity: 109 Low Res Light Level : 6.33 lx HighRes Light Level : 0.00 lx HighRes2 Light Level : 0.00 lx

Sensitivity: 119 Low Res Light Level : 5.80 lx HighRes Light Level : 0.00 lx HighRes2 Light Level : 0.00 lx

[kizniche]

No prob. I got that covered. I'll push a new release for you to upgrade to, to test, in a few.

[kizniche]

The HighRes and HighRes2 Light Levels are at 0. Is that because your light levels are very low where your sensor is? Can you shine a light on it and rerun the code?

[cohe4ko]

It's night here :) And my greenhouse with raspberry pi is far from me. I just remotely turned on lighting there and the light from lamps don't shine to sensor directly. that's why is such situation.

[kizniche]

I think I did it. I'm testing all I can right now, without having the sensor. I'll push an update (5.0.14) before I head off to dinner.

[cohe4ko]

That's great :) Thank you once more.

[kizniche]

I just released v5.0.14 and performed an upgrade with one of my dev systems without error. Upgrade when you can and let me know if the new sensor works.

[cohe4ko]

One more issue - there is no bh1750 sensor in list of available sensors in live graphs.

[cohe4ko]

Sensor works properly.

[kizniche]

Good to hear! I'll include the update to fix the graph selection in the next release. In the meantime, you can change line 824 of flaskutils.py from:

        if each_sensor.device in ['CHIRP', 'TSL2561']:

to

        if each_sensor.device in ['BH1750', 'CHIRP', 'TSL2561']:

Then restart apache (sudo /etc/init.d/apache2 restart) and that should fix it.

[kizniche]

I'm actually quite surprised the sensor worked on the first try ;)

[kizniche]

I even included the ability to select resolution and sensitivity, which made it more complex.

[kizniche]

Closing this issue. Reopen it if the code edit above doesn't work or, when the next release comes, it doesn't fix the display list for graphs/exports.
