You are not receiving flood notifications from your Lyric Panel via HomeKit because HomeKit does not send out specific notifications for flood zones. But HomeKit can send a generic Lyric System Alert if the flood zone has a Response Type of 24-Hour Auxiliary and notifications are enabled. Apple HomeKit can only provide specific zone notifications for a small selection of Response Types. These are Entry/Exit 1, Entry/Exit 2, Perimeter, Interior Follower and Interior w/ Delay. A flood sensor would not normally use any of these Response Types. As a result, you cannot receive specific HomeKit alerts for an activated flood sensor under normal circumstances. The only HomeKit alert you can normally receive regarding a flood sensor on a Lyric System is a General Lyric System Alert. This is possible because you can configure a flood zone with a 24-Hour Auxiliary Response Type. The 24-Hour Auxiliary Response Type produces an audible alarm when ever the sensor is faulted. Please note that you should tell your monitoring station that the zone is for a flood sensor. Otherwise, they may think it is a medical alarm. If you want to receive General Lyric System Alerts during audible alarm events, you must enable the option from within HomeKit. All audible alarms are grouped together under this category, and they are configured collectively. When configuring this setting, you should have "Include in Status" and "Allow Notifications" both enabled. This setting is also where you can set who receives the notifications and when they are sent out. However, there is one very important thing to remember if you decide to rely on General Lyric System Alerts. These alerts do not differentiate between different types of sensors. They will not display the Device Type or the specific zone. In other words, you really won't have a way to tell the difference between fire, CO, temperature and flood alerts from HomeKit. All you will get is a generic alert. It is then up to you to determine what triggered the Lyric. You can see an example of a General Lyric System Alert in the picture below: Fortunately, there is a way to know exactly which type of alarm occurred on your Lyric System. That is by using Total Connect 2.0 alongside HomeKit. By using TC2, you can receive text and/or email alerts that inform you exactly which zone was faulted and caused an alarm. We have a helpful FAQ that explains the differences between TC2 and HomeKit.
