The konnected system is not an alarm panel. The connected board can REPLACE your alarm panel or interface to it (to read the sensors) but it will not provide the same functions of an alarm panel as far as having keypads and an interface to interact with it.
Just to clarify...you are looking for an alarm panel that has some type of TCP-IP or serial interface to allow you to have an independent alarm system but also use those sensors with Hubitat, correct? You are not trying to use Hubitat Safety Monitor as your alarm system.
What are your other requirements? Does the panel have to have professional monitoring? Cell backup? Are you planning on interfacing the armed state of the alarm to HSM to get remote notifications? Are you looking for a DIY or professionally installed panel?
