Unofficial EasyHome Hygro PremiumSP speed controller via exposed web and REST API

Project description

EasyHome Hygro Premium SP controller

Unofficial speed controller for EasyHome Hygro Premium SP via web. It exposes an API REST server with a simple frontend in order to control the current speed.

Requirements

  • Raspberry PI
  • Up to 7 relays
  • Software: pip
  • Development Software: pip, node, yarn

Setup

We need to interface our Raspberry PI to the EasyHome Hygro card through relays. There are currently two types of configurations available:

  • With normal relays. When the Raspberry PI has not started is in QUIET speed.
  • With solid state relays.

NOTE: If you want to shut down the EasyHome Hygro when the Raspberry PI has not started with normal relays use the solid state configuration.

Installation

sudo pip install hygro

Web server

Run the command hygro-premium-sp-server. If do you prefer to have it in a background process you can run as nohup hygro-premium-sp-server &

It will open a web frontend in Raspberry PI at port 21000. It exposes an API rest too in the same port.

API REST

    "real_ratio": 1.00
  }
}

GET /api/configuration

{
