arduino-xpl-heatpump-controller

Control a Panasonic heat pump/split unit air conditioner with Arduino using the xPL protocol Currently supports at least models

• Panasonic E9/E12-CKP and E9/E12-DKE (Panasonic remote control P/N A75C2295 and P/N A75C2616)
• Midea MSR1-12HRN1-QC2 + MOA1-12HN1-QC2, sold as Ultimate Pro Plus Basic 13FP in Finland (Midea remote control P/N RG51M1/E)

Some xPL-perl example commands:

xpl-sender -m xpl-cmnd -t xpl-arduino.heatpumpctrl -c aircon.ckp power=0 mode=2 fan=3 temperature=23
xpl-sender -m xpl-cmnd -t xpl-arduino.heatpumpctrl -c aircon.dke power=0 mode=2 fan=3 temperature=23
xpl-sender -m xpl-cmnd -t xpl-arduino.heatpumpctrl -c aircon.midea power=0 mode=2 fan=3 temperature=23
