[BUG]: Missing Sensirion SHTxx Sensors?

[shane64]

Setup:

• TerrariumPI version: 4.8.3
• Install: Manual
• Raspberry PI: 2B Rev 1.1

Describe the bug Updated from 4.6.1 to 4.8.3 (via SD card wipe and re-install from scratch without using a backup) and I no longer see the Sensirion SHTxx temperature/humidity sensors in the list when adding new sensors. These were available in version 4.6.1. Have they been deprecated?

To Reproduce / Installation steps Clean install (no backups used) of 4.8.3 using manual method on Buster Lite.

Expected behavior Able to select the Sensirion SHT3x sensor to use my temp/humidity sensor as before.

Screenshots Screenshot of the list I see (it appears to be alphabetical). I do no see those sensors anywhere else in the list.

Additional context Just looking to see if these have been deprecated or if they can be turned on again? I ran another "sudo ./install.sh" to see if that would add them but that didn't work. I have reviewed the FAQ and release notes since version 4.6.1 but see no mention of their removal.

They should be available:

But I get the feeling not all libraries are loaded... So I changed some logging. Do a git pull and run in debug mode: https://theyosh.github.io/TerrariumPI/faq/how-to-debug-terrariumpi/

When it starts in debug mode, you should see some warnings about not able to load some sensor files. Please post the log here so I can see what the error message is.

Hello.

Thank you for the quick reply. I have pasted the log with the relevant entry here:

2024-03-11 19:49:09,134 - INFO    - terrariumEngine       - Starting up TerrariumPI 4.8.3 on a Raspberry Pi 2 Model B Rev 1.1 ...

Please advise next steps.

Thank you.

Ok, this is strange and tricky... Can you do the following:

1. cd /home/pi/TerrariumPI/
2. source venv/bin/activate
3. python -V

paste output here

[shane64]

Output is as follows:

Python 3.7.3

Thank you.

[theyosh]

Hmm, this is very strange... So could you try the following:

1. cd /home/pi/TerrariumPI/hardware/sensors/
2. rm shtxx_sensor.py
3. wget https://raw.githubusercontent.com/theyosh/TerrariumPI/main/hardware/sensor/shtxx_sensor.py

And then restart in debug mode. Could be that the shtxx_sensor.py was some how corrupt.

[shane64]

Followed steps 1 through 3 and restarted in debug mode and receive exactly the same error as before. The file size was identical between the shtxx_sensor.py that was there and the one that was downloaded.

Thank you.

[theyosh]

Ok, next test:

1. cd /home/pi/TerrariumPI/
2. source venv/bin/activate
3. pip install sensirion-i2c-sht sensirion-i2c-driver

and paste the outcome here?

[shane64]

Output is as follows:

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: sensirion-i2c-sht in ./venv/lib/python3.7/site-packages (0.4.0)
Requirement already satisfied: sensirion-i2c-driver in ./venv/lib/python3.7/site-packages (1.0.0)

The error remains. Thank you.

[theyosh]

Hmm, so lets try to downgrade some libraries:

1. cd /home/pi/TerrariumPI/
2. source venv/bin/activate
3. pip install sensirion-i2c-driver==1.0.0 sensirion-i2c-sht==0.3.0 adafruit-circuitpython-sht31d==2.3.20

And rerun in debug mode. These are the old libraries in version 4.6.1. Lets see what this does.

The same error as before continues to occur when run in debug mode. Thank you.

[theyosh]

So I found the issue. An external library was causing this. So again, some commands to execute:

1. cd /home/pi/TerrariumPI/
2. source venv/bin/activate
3. pip install adafruit-circuitpython-typing==1.10.1

This should fix it. I am currently working on the installer to fix for the future.

[theyosh]

Did the last actions fixed your SHT sensors?

[shane64]

Hello,

My apologies for the delay. That seems to have gotten rid of the error and I can now add the SHT3X sensors. Thank you! I assume that I should re-upgrade the sensirion-i2c-sht library to 0.4.0?

Now that I have the sensor added, I cannot communicate with it, but suspect that it's a hardware issue that I still haven't managed to solve (though I've exhausted all the ideas that I know of to try and get it working). It's wired up the same way it was before with the previous TerrariumPI version where it was working (and I can see it in i2cdetect -y) but I'm running out of things to try and figured I'd ask if there's any way that there's a software explanation that might solve it? (It's an SHT30, and I've tried a second on in it's place thinking it had gone bad with the same results)

Errors as follows:

2024-03-15 14:52:14,908 - WARNING - terrariumEngine       - Could not take a new measurement from sensor Sensirion SHT3X sensor humidity named 'Humidity' at address '0x44,0'. Tried for 0.00 seconds. Skipping this update.

Error getting new data from sensor Sensirion SHT3X sensor temperature named 'Temperature' at address '0x44,0': I2C transceive failed: [Errno 121] Remote I/O error

If not, I'll carry on hardware troubleshooting and recommend you close this issue.

Thank you very much for your help!

[theyosh]

You address is incorrect. I2C bus start at 1. So use address 0x44. Remove the ,0 part. I guess that should do the trick

[shane64]

Thank you. I've actually got it running on bus 0 specifically as I have two of these sensors, one on each bus (as their addresses are fixed and thus conflict). Funny that I can't even get the second one to show up on bus 1 using i2cdetect (whereas the one I originally ran worked fine on bus 0). As I say, this is likely a hardware error (read: user error) and I'll carry on troubleshooting. Thank again.

[theyosh]

Is there something I can do. The only thing I can think of is creating small test code like this: https://sensirion.github.io/python-i2c-driver/quickstart.html The example is using I2C bus 1 (at the end of the code).

If that also fails, you know you have a hardware failure.

Else I would like to close this issue. As I cannot help much more.

[theyosh]

Where you able to fix this? Can I close this issue?
