External converter

import * as fz from "zigbee-herdsman-converters/converters/fromZigbee";
import * as exposes from "zigbee-herdsman-converters/lib/exposes";

export default {
    zigbeeModel: ["DCH-B122", "DCH-b122"],
    model: "DCH-B122",
    vendor: "D-Link",
    description: "mydlink smart motion sensor",
    fromZigbee: [fz.ias_occupancy_alarm_1_with_timeout, fz.ias_occupancy_alarm_1_report, fz.battery],
    toZigbee: [],
    exposes: [e.occupancy(), e.tamper(), e.battery_low(), e.battery()],
    configure: async (device, coordinatorEndpoint) => {
        const endpoint = device.getEndpoint(1);
        await reporting.bind(endpoint, coordinatorEndpoint, ["genPowerCfg"]);
        await reporting.batteryPercentageRemaining(endpoint);
    },
};

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

State still shows alarm_1 and alarm_2 instead of just occupancy & tamper. Not sure why alarm_1 shows true while occupancy shows false.
{
"alarm_1": true,
"alarm_2": false,
"battery": 100,
"battery_low": false,
"linkquality": 104,
"occupancy": false,
"tamper": false
}

Start with the supplied DCH-B122 external converter and compare its fromZigbee handlers and exposes with the reported database entry and state payload. Confirm the resulting state exposes occupancy and tamper without alarm_1 or alarm_2, and that motion events produce the expected occupancy value.
