You might try asking this question in the main Intellifire driver thread. I'm not a HomeKit user, so I don't know how to advise here, but inetjnky (who is active in that thread) does use HomeKit and might have some advice.
If there's something that HomeKit needs that I can add to the driver, I may be able to add that. (I've done this to get Google Home Community working.) I just don't know where to look for that information for HomeKit.
