UPS-Display

Python3 script to show info about APC UPSes on a e-Paper display and a RPi Zero W.

What you need

• Raspberry Pi Zero W with Raspberry Pi OS installed (former name was Raspbian)
• Waveshare e-Paper 2.13inch Display

Before you start, make sure you have the SPI interface enabled on your Raspberry

sudo raspi-config
Choose Interfacing Options > SPI > Yes  to enable SPI interface
sudo reboot

Displayed info:

• Status
• Load
• Charge
• Time left
• Voltage
• Firmware
• Serial
• Model

Setup:

1. Install the required packages to build BCM libraries:

    sudo apt-get install gcc make libc-dev 
   

2. Download and install BCM2835 libraries:

    wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.60.tar.gz
    tar zxvf bcm2835-1.60.tar.gz 
    cd bcm2835-1.60/
    sudo ./configure
    sudo make
    sudo make install
   

3. Install python3 and the required libraries and modules:

    apt-get install python3 python3-pip python3-pil python3-numpy python3-rpi.gpio python3-smbus wiringpi
    python3 -m pip install spidev
    python3 -m pip install RPi.GPIO
    python3 -m pip install setuptools
    python3 -m pip install apcaccess
   

4. Now you can clone this repository, open the file upsdisplay.py and modify "YOUR_RASPI_IP" with the IP address of your Raspberry Pi.

5. To run the script in background execute:

    python3 upsdisplay.py&

This project has been realized for personal use. I am not a developer, it is the first application I write in Python and it may not be optimized or formally correct.
