Hi I was trying to add a mh-z19 sensor, connected like this: https://pypi.org/project/mh-z19/ I went to the setup setup data page and got this error log: Error (Full Traceback):

What have I done wrong? I'm a complete Noob to the pi

Can you list what you did in steps I can follow to reproduce this issue?

Sorry - can't remember clearly enough, trying to re-create. This might take a while, I'll get an action list to you when done.

Hi

Well I've started from scratch to get a clean install. It seems to work now. I'm going to post the action list anyway in case it helps someone else in the future. Thank you for looking at this.

A list of install actions follows: On PC (Win10) Format SD card using SD Card Formatter v5. Write 2019-04-08-raspbian-stretch.img to card using Win32 Disk Imager. Raspberry Pi 3 Model B+ Plus 1.4GHz Quad Core 64Bit 1GB RAM (2018 Model) connected to monitor via HDMI/DVI cable, dell wireless keyboard & mouse, using a power source that has the following output: 5V DC 2500mA. Sensors connected: MH-Z19 to GPIO 5v power & ground, RX to GP1014 Tx to GP1015. AM2315 to GPIO 5v power & ground, SDA to GP102 (2W 10Kohm resistor upload to power) SCL to GP103 (2W 10Kohm resistor upload to power). SD card safely removed from PC, inserted into Pi and power-on. Raspbian resized root system automatically and rebooted. Time zone etc set to U.K., British, London (local). Password Blanked off. Screen left as-is. Wi-Fi found & password entered. Software update accepted & installed. Note made of Pi's IP address. Restart.

Check AM2315 sensor: Command window: sudo apt-get update sudo apt-get upgrade sudo reboot sudo apt-get install i2ctools sudo apt-get install python-dev sudo apt-get install libi2c-dev sudo raspi-config In interfacing options turn on I2C In advanced options expand filesystem, reboot. Command window: sudo i2cdetect -y 1 (twice AM2315 found at address 5c)

Check MH-Z19 sensor: sudo apt-get install git git clone https://github.com/UedaTakeyuki/mh-z19.git cd mh-z19 ./setup.sh (y option selected) Reboot sudo raspi-config In interfacing options turn on ssh and serial Reboot (ignore warning) Command window: sudo python -m mh_z19 (null? - check wiring – OK – think I killed it. This worked before. Power down, disconnect & order another).

Install Mycodo: Power up Get fed up with warning and: Command Window: sudo raspi-config (enter a password) Check config has been done for Mycodo from the readme (on PC, not Pi) – yes Command window: Curl -L https://raw.githubusercontent.com/kizniche/Mycodo/master/install/install | bash Agree to license After install reboot On PC open Firefox & navigate to Pi’s IP address Ignore security warning, agree and set-up admin user. Login Go to set up data page & it works!? Could the dodgy sensor have upset Mycodo?

I was more wondering the steps you took from within the Mycodo web interface to cause the error, but thank you for the detailed steps. I don't see anything that should cause that error. The error disappearing from a reinstall suggests it was an issue with your first install that caused it. In any case, I'm glad it was resolved with a reinstall.
