Just to re-iterate on my question above (and potentially answer to the OP), the Ring Alarm is working fine in Cyprus with door/window and motion sensors, so I expected to be able to pair it with the new flood/freeze sensors. Instead when trying to add the new sensors I don't have the option to add them through the app and only new door/window and motion sensors can be added. The only location related limitation I found so far (other than this question) is that you can only use the system on the "self monitored" mode. Even so, it pairs nicely with the rest of my Ring devices, though I would love to also have the external Floodlight syren sounding when the alarm is triggerred.
