Have a NX8e and having some trouble with it. Currently using a Alula cell box for monitoring. Hoping to get the problems resolved but if it turns out to be much cost wondering what my options are for different model/brand replacement that is currently in production. This is a 20 year old system and I know some companies have gone away. Have 16 zones in main partition and 8 in a separate building with wire connection between. All wired zones. Have thought of using the serial port for home automation things but haven't gotten around to it so would consider that capability a plus but not mandatory.
