Need help on adding new device support (BYUN Gas Sensor)

[oscarliuyc]

I have been trying to add support to a gas sensor, BYUN M415-6C. I can successfully added it to Z2M and the state will change when testing or gas leakage detected. However, the gas state remains 'detected' afterwards forever. Appreciate your help.

devices.js

{
    zigbeeModel: ['GAS  SENSOR     '],
    model: 'M415-5C',
    vendor: 'BYUN',
    description: 'Combustible gas sensor',
    fromZigbee: [fz.ias_gas_alarm_1, fz.linkquality_from_basic],
    toZigbee: [],
    exposes: [e.gas(), e.battery_low(), e.tamper()],
},

when testing or detecting gas leakage, the follow message was logged:

Received Zigbee message from '0x00124b0013eb2423', type 'commandStatusChangeNotification', cluster 'ssIasZone', data '{"extendedstatus":0,"zonestatus":33}' from endpoint 1 with groupID null
debug Received Zigbee message from '0x00124b0013eb2423', type 'raw', cluster '1034', data '{"data":[24,0,10,0,0,16,0],"type":"Buffer"}' from endpoint 1 with groupID null
debug No converter available for 'M415-5C' with cluster '1034' and type 'raw' and data '{"data":[24,0,10,0,0,16,0],"type":"Buffer"}'

Seems "fz.ias_gas_alarm_1" can only handle change in state when gas is detected and I need another converter to change the state back to false. I tried to write a converter to handle cluster 1034, type 'raw' and the data set, but I got stuck. Can somebody help?
