I never wrote an AC driver for HubithingsReplica. I did not want to author competing implementations of the same device and someone else had already written.
Before HubithingsReplica, I did create the following integration for Samsung Appliances. It contains the HVAC, an artificial thermostat (so it can work with the Hubitat thermostat dashboard implementation) and also has a toggle panel light command. See below thread link.
If you choose, be sure to read the installation instructions. Any questions should be posted on the below thread as well.
