For those experiencing problems with pairing the Iris keypads and having the network light continue to flash, here’s one solution that works for me.
After the initial pairing is successful, the network light will continue to blink. Disregard this for a moment, and exit device inclusion. Open the device in the mobile app to ensure that it’s sending Events to ST. This indicates that the keypad has paired successfully. Once events have been confirmed, press the tamper switch on the back 5 times. Within 1-2 seconds the network light will stop blinking and the keypad will remain connected.
I’ve successfully replicated this process on all 3 of my Iris keypads as part of migrating to the v3 hub.
