Add support for EKH - Githubissues

Arnold-n / P1P2MQTT

Monitor and control Daikin/Rotex (hybrid/Altherma) heat pumps via the 2-wire P1/P2 thermostat interface with an ATmega328P, ESP8266, and electronics. The P1P2Serial library and P1P2Monitor program perform low-level bus operation, the P1P2-bridge-esp8266 program interprets data from/to MQTT supporting Home Assistant MQTT discovery. P1P2Serial may also be used for other Japanese Home Bus System based standards: DIII-NET (F1/F2) bus, Mitsubishi M-Net bus, Toshiba TCC-Link, Hitachi H-link, Panasonic/Sanyo SIII-Net, Haier, York, and others.

I was able to map the outside temperature. I am not 100% sure because I have only observed two values 12 and 10 and I could find them at that position. Also not sure if the encoding is correct, I first need more data.

This is now sent as S1 instead of T1. Does S mean setting and T temperature reading?

Indeed; 1 indicates the source (heat pump), S/T/M/.. the (assumed) parameter category as defined in the code by CAT_SETTING/CAT_TEMP/CAT_MEASUREMENT/..
