telegram bot 제 2탄

텔레그램 봇을 만들어 보았었지요.

이번엔 그 두 번째 이야기.

HVAC IR Remote라는 라즈베리파이에 올릴 수 있는 IR Transceiver를 구매하고, 원격에서 집에 있는 장치를 리모콘 조작하듯이 켜고 끌 수 있는 것을 만들어 보았습니다.

        Setting up HVAC IR Remote for LIRC
    
    
        
    


Instructions


https://www.hackster.io/austin-stanton/creating-a-raspberry-pi-universal-remote-with-lirc-2fd581


Install lirc package

sudo apt-get install lirc

Configure kernel module

vi /etc/modules
lirc_dev
lirc_rpi gpio_in_pin=18 gpio_out_pin=23

note I/O port is different than above documentation.
You can find GPIO port for HVAC IR Remote in arduPi.cpp

vi /etc/lirc/hardware.conf

see above document

vi /etc/lirc/lirc_options.conf

https://raspberrypi.stackexchange.com/questions/50873/lirc-wont-transmit-irsend-hardware-does-not-support-sending
set driver to ‘default’


Record IR signal or obtain configuration file.

My testing board didn’t work as expected.
I can only control IR LED, two buttons, two indication LEDs. but can’t read IR signal. I don’t know board is broken or something.

following my own blog https://www.dgkim.net/wordpress/2017/08/24/telegram-bot-%ed%85%8c%ec%8a%a4%ed%8a%b8-%eb%85%b8%ed%8a%b8/

I tried

git clone https://github.com/python-telegram-bot/python-telegram-bot

cd python-telegram-bot
git submodule update

But, today I changed plan.

I referenced https://github.com/python-telegram-bot/python-telegram-bot/tree/master/examples

quickly created firstbot.py
