How to use Python 3.5+

In order to run the software on Python 3.5 or higher, the installer has to be run with an extra parameter. This is needed in order to install all the needed Pytho 3.5+ modules. After that, the start up command in the file /etc/rc.local needs to be adjusted. By default the installer is using Python 2.7. During the installation the used Python version is in the left upper corner.

  1. cd /home/pi/TerrariumPI
  2. sudo ./install.sh 3
  3. sudo ./start.sh 3

And change the command in /etc/rc.local from /home/pi/TerrariumPI/start.sh to /home/pi/TerrariumPI/start.sh 3

Use and enable NGINX server on port 80

In order to run the webinterface on port 80 in stead of 8090, you can install nginx and use the vhost configuration in the contrib folder. Execute the following commands:

  1. sudo apt install -y nginx
  2. cd /etc/nginx/sites-enabled
  3. sudo rm default
  4. sudo ln -s /home/pi/TerrariumPI/contrib/nginx.conf terrariumpi
  5. sudo service nginx reload

This should make the web interface be accessible on http://[terrariumpi_IP]. Either use port forwarding on your router, or register your pi at dataplicity and use their wormhole feature to make your Pi accessible on the internet.

SMTP and/or SSL errors during startup.

If you see the following errors during startup of the software after a reboot, that is somewhat normal. The OS random number generator is not yet ready in order to create secure connections. This will become normal working again after 30 seconds till 1 minute. Just leave the software running and it will become steady.

Increase logging

TerrariumPI log all actions in a log file at log/terrariumpi.log. By default it logs INFO, WARNING and ERROR messages. In order to get debug messages change the file: logging.conf and change

[handler_fileHandler]
class=logging.handlers.TimedRotatingFileHandler
level=INFO

to

[handler_fileHandler]
class=logging.handlers.TimedRotatingFileHandler
level=DEBUG

And restart TerrariumPI

How to translate

See the Translation page for creating a new translation

How to test a DHT11, DHT22 or AM2303 sensor

After installation of TerrariumPI there is a folder called 'Adafruit_Python_DHT' in the 'pi' user home folder. Enter the examples folder for a simple test script.

  1. cd ~/Adafruit_Python_DHT/examples
  2. ./AdafruitDHT.py 22 24
  3. Temp=21.6* Humidity=70.6%

Where value 22 is one of: 11 for DHT11 sensor, 22 for DHT22 sensor and 2302 for AM2303 sensor. And 24 is the value of the pin number in BCM mode https://pinout.xyz/

In order to use it with TerrariumPI translate the BCM number to physical layout using https://pinout.xyz/. In the above case the BCM 24 port is physical number 18. Therefore use value 18 in the software.

If the output is out of range, for example humidity is above 100%, this is an indication that the sensor is not working properly and can have a hardware failure. This has to be solved first before using it with TerrariumPI.
