Lock works fine using the August app - however integration with Homekit is poor.  Status reports correctly to Homekit but unable to get the lock to lock or unlock via Homekit thus rendering any Homekit automations useless.  Also lock loses WI-Fi daily but does connect back quickly - notifications are annoying. Would not recommend for Homekit users.  Only support is via email and I am a week into trying to troubleshoot with back and forth emails.
