Description:

automationhat 1.0.0

Automation HAT is a home monitoring and automation controller featuring relays, analog channels, powered outputs, and buffered inputs (all 24V tolerant). This library will also work with Automation HAT's smaller siblings - Automation pHAT and Automation HAT Mini.

Installing
Full install (recommended):
We've created an easy installation script that will install all pre-requisites and get your Automation HAT
up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal
on your Raspberry Pi desktop, as illustrated below:

In the new terminal window type the command exactly as it appears below (check for typos) and follow the on-screen instructions:
git clone https://github.com/pimoroni/automation-hat
cd automation-hat
./install.sh

Note Libraries will be installed in the "pimoroni" virtual environment, you will need to activate it to run examples:
source ~/.virtualenvs/pimoroni/bin/activate

Development:
If you want to contribute, or like living on the edge of your seat by having the latest code, you can install the development version like so:
git clone https://github.com/pimoroni/automation-hat
cd automation-hat
./install.sh --unstable

In all cases you will have to enable the I2C bus (and SPI for Automation HAT Mini):
sudo raspi-config nonint do_i2c 0
sudo raspi-config nonint do_spi 0

FAQ
What is the accuracy and resolution of the Automation HAT
The ADS1015 is a 12-bit ADC, but since the 12th bit is the sign-bit there are only 11-bits of resolution available for positive voltage readings. The input voltage for 24v channels is scaled from 0-25.85v (25.85 rather than 24 due to how the resistor divider is set up) to 0-3.3v.
Since the full-scale range of the ADC is set to 4.096v, this means that 0-3.3v gives only ~1649 possible usable values making the input measurement granularity somewhere around 0.015v (25.85 / 1649) for the 24v inputs and 0.002v for the 3.3v input.
