Drivers for various ancillary hardware used in reef-pi, based on reef-pi/hal

Introduction

This repository contains a set of drivers for ancillay hardware used in reef-pi project. They are intended to have minimal dependencies (most cases only reef-pi/rpi). These drivers API are not stable, and subjected to change as per reef-pi's requirement.

Currently available drivers

• Kasa hs300, hs303, hs103, hs110 smart switches and power strips
• Digital Loggers web power switch
• Tasmota based smart outlets
• reef-pi open source ph_board: ADS1115 based pH circuits
• PCA9685 PWM driver
• ADS1x15 Analog to digital converter
• Atlas Scientific ezo ph circuit
• Blue acro pico-board: ATSAMD10 pH adapter for the blueAcro Pico board
