As Ring is an alarm system I understand it's need for security and not opening up potential vulnerabilities by allowing other systems access but a "read only" status of system arm state would do wonders for home automation. Examples: 1) system is armed and goes into alarm -> ISY turns on all lights. 2) system goes from disarmed to armed -> ISY waits x min and then turns off all lights. 3) system is armed and goes into entry delay -> ISY turns on hall light near keypad.
If we could just get a status only output of disarmed, home, away, entry delay, exit delay, and alarm it would both keep ring secure and allow so much more function of home automation!
