Decode_Hisense_Aircond

Decode and transmit Hisense Aircond IR codes using RPi and LIRC

Prerequisites

External Python Libraries

Update PIP

python -m pip install --upgrade pip

Install required libraries

pip install virtualenv

LIRC Setup

Follow steps to setup LIRC for Buster

https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=235256

Run command to generate mode2 file:

mode2 -d /dev/lirc1  -m > test.mode2

Aim remote at RPi and Ctrl+C once done

Setup

Workspace Creation

Navigate to new workspace folder

cd path/to/workspace

Download from Git

git clone https://github.com/Palt0n/kh-serverstats.git

Setup python virtual environment with venv

Create python virtual enviroment with venv

python -m venv env

To activate venv

source env/Scripts/activate

To check if venv is activated

which python

This command should return the path for python.
This path should be located in the local env folder

If you want to exit venv later (DONT EXIT NOW!), use

deactivate

Download external python libraries

Have to repeat the pip upgrade in venv

python -m pip install --upgrade pip

Ensure that venv is activated, then install the libararies using pip

pip install -r requirements.txt

Or run

pip install numpy
pip install matplotlib

Run

To obtain Y for X values

python plot_mode2.py

Adjust value until a good R squared value is obtained

Once good values are obtain, edit parse_mode2.py with the new values and run:

python parse_mode2.py Hisense_Aircond_Power.mode2.example

Run command to store conf file:

irrecord -a test2.lirc.conf
sudo lircd --device /dev/lirc0 --driver devinput
sudo lircd --device /dev/lirc0
sudo cp test2.mode2 /etc/lirc/lircd.conf.d/test.conf
sudo /etc/init.d/lirc restart

Developer Misc

Create requirements.txt file

pip freeze > requirements.txt
