Basic help: What hardware is needed?

[pmorch]

I think I'm missing some context. I have a Mitsubishi heat pump that I want to control, but what hardware do I need?

Please bear with me. I'm new to Arduino... This project is for Arduino, correct?

The README.md says:

A python port has been made to be compatible with Raspberry Pi

Can I then use a Raspberry Pi without an Arduino? But then what hardware do I need to actually send the IR signals? I already have a USB Infrared Toy v2 lying around. And does it have to be a Raspberry Pi or can I use it with any PC?

Or do I need an Arduino also?

There is a "HVAC_Broadlink" folder supporting a Broadlink IR RM2. SendHVACCmdToRM2.py says:

I'ts a template/code example, no ther pretention

So I guess that is not what I should be using. There is also a "HVAC_ESP8266" folder which says:

I have used ESP 8266 ESP-12 Module

And then I connect an IR LED via a transistor to the ESP 8266 ESP-12 Module "somehow"?

So which of these does one need?

• Raspberry Pi
• Arduino, e.g. Arduino Uno Rev3
• ESP 8266 ESP-12
  • IR diode
  • transistor
• Broadlink RM Pro
• (Can I use my USB Infrared Toy v2?)

... a little overwhelmed ...
