To install just copy both the dscalarm.yaml file and the subdirectory "dscKeybusInterface" (including all the contained dsckeybus*.cpp files) into your main esphome directory on home assistant and compile using the esphome application. It seems that dscalarm.yaml is completely rewritten and the files that were in the subdirectory "dscKeybusInterface", are now placed in components. Is it correct?
Ignore that statement. It's old. Yes, the files are now in components but you don't need to copy them. You can just compile the yaml and it will fetch them.
