PiModule

A node package helper to control your UPS PIco HV3.0A/B/B+ HAT

This library was not developped by the PiModules(R) UPSPIco company. Any query/issue concerning their product won't find answers here, sorry :/ Feel free to refer to their official github repo: https://github.com/modmypi/PiModules

Be aware that this package uses exclusively await/async, no callbacks ;)

Getting Started

The PiModule documentation can be a bit tricky to read. So here is a small helper of the most common features you may want to use. Once you've followed the installation process, you'll be able to use the following functions:

• Set pimodule addresses
• Get pimodule temperature
• Set shutdown timer
• Get pimodule battery level
• Get/set pimodule powering mode (battery or power)
• Set backed auxiliary power
• Get pimodule running state
• Set buzzer state
• Generate sounds
• Get/set pimodule bistable relay state
• Set leds (orange, green, blue)
• Set events on keys (named A, B and C)
• Get/set pimodule fan mode (automatic, manual, disabled)
• Get pimodule fan state
• Get/set pimodule fan speed
• Set temperature threshold

Prerequisites

You'll need a UPS PIco HV3.0A/B/B+ HAT, you can order it here: https://pimodules.com/plus-advanced

You'll also need to get the installation process right. You can choose one of two ways:

• Ansible

Make it easy to reproduce via Ansible in case your rasperry pi fails! To use the playbook provided, just clone this repository on your dev machine:

git clone https://github.com/RomeHein/pimodule.git

You'll need at least ansible installed. Make sure to change the local address of your raspberry pi as well as the correct user in the following command:

cd /ansible
ANSIBLE_HOST_KEY_CHECKING=false ansible-playbook pimodule.yml -i raspberrypi.local, --user=pi --ask-pass

• Script: installer.sh

Just copy past the script installer.sh on your raspberry pi. Make sure you have the right permissions to run the script:

    chmod +x installer.sh

And run it with sudo:

sudo ./installer.sh

Alternatively, you can run it via npm once the repo is cloned on your raspberry pi:

sudo npm run installer

Installing

Just install via npm:

npm i pimodule --save

Usage

Import the module and start using it:

    const PiModuleHelper = require('pimodule')
    const piModule = new PiModuleHelper()

    const state = await piModule.piModuleIsRunningProperly()
    console.log(`PiModule is running: ${state}`)

When you instantiate pimodule, make sure you are using the right set of addresses: Three are available: 'default', 'alternate' and 'noRtc' If you are using 'alternate', instantiate the module like so:

    const PiModuleHelper = require('pimodule')
    const piModule = new PiModuleHelper('alternate')

    // Plays imperial starwars march from pimodule built in buzzer
    await piModule.playSounds([[220, 700], [220, 700], [220, 700],[174, 525], [261, 175], [220, 700], [174, 525], [261, 175], [220, 1400]])

Running the tests

Tests seem a bit useless here as functions are very simple wrappers of the i2c-bus node library (which is heavily tested). However I would make sure the library matches the current implementation of the PiModule firmware before using pimodule. You can check that by running directly on the raspberry pi:

npm run check

This will run tests without mocking the i2c-bus library. That way we are sure addresses are correct
