External definition

const m = require('zigbee-herdsman-converters/lib/modernExtend');

const definition = {
    zigbeeModel: ['LNAWTC2WBS'],
    model: 'LNAWTC2WBS',
    vendor: '',
    description: 'Automatically generated definition',
    extend: [m.iasZoneAlarm({"zoneType":"generic","zoneAttributes":["alarm_1","alarm_2","tamper","battery_low"]})],
    meta: {},
};

module.exports = definition;

What does/doesn't work with the external definition?

Alarm 1 seems to represent the water leak sensor state.

Alarm 2 doesn't seem to correspond to anything. It doesn't appear to ever change from True

Tamper always reads Clear, this device doesn't seem to have a tamper switch so I don't think this should be exposed

Battery low always reads True, tested with several brand new batteries

When I put sensor in water, this is the log I see:

When I remove sensor from water, this is the log I see:
