Hi , thanks for reply.
But in this case we do need to leard code by code. Is there any way to use climate platform and only point to ir channel at AG8 ?

One more thing, I could not make it work with homeassistant. It is auto discovering, but did not add to device lists. Using 3.9.1 kcs and latest HA update.
