Develco Smoke Alarm sensor: Temperature & battery not read?

[paddenstoeltje]

Bug Report

What happened

I've bought multiple Develco's Smoke Alarm sensors SMSZB-120. I'm able to configure them successfully and trigger the alarm manually, however the temperature and battery values are not read / updated? I have checked the log files (debug mode) when pairing the devices, however I cannot find the reason why the temperature is not showing up.

What did you expect to happen

As the smoke alarm also features a temperature sensor, I would expect to have a temperature reading over MQTT. The same is true for the battery value.

How to reproduce it (minimal and precise)

Each time the smoke alarm gives an update, everything is updated, except the temperatures and the battery values. Example of an update:

zigbee2mqtt:debug 2020-06-10 19:47:48: Received Zigbee message from '0x0015bc00310045ad', type 'commandStatusChangeNotification', cluster 'ssIasZone', data '{"zonestatus":48,"extendedstatus":0}' from endpoint 35 with groupID 0
zigbee2mqtt:info 2020-06-10 19:47:48: MQTT publish: topic 'zigbee2mqtt/0x0015bc00310045ad', payload '{"voltage":3200,"battery_low":false,"linkquality":68,"enrolled":false,"smoke":false,"tamper":false,"supervision_reports":true,"restore_reports":true,"trouble":false,"ac_status":false}'

Debug Info

Adapter hardware: CC2531
Version of Zigbee2Mqtt: 1.13.1-dev
Coordinator version: 20190608
I attached the develco manual, together with my pairing log.

Thanks for your time!

The reason is that the configure() fails. Please try changing the definition in devices.js to

{
    zigbeeModel: ['SMSZB-120'],
    model: 'SMSZB-120',
    vendor: 'Develco',
    description: 'Smoke detector with siren',
    supports: 'smoke, warning, temperature',
    fromZigbee: [fz.temperature, fz.battery, fz.ias_smoke_alarm_1, fz.ignore_basic_report, fz.ignore_genOta],
    toZigbee: [tz.warning],
    meta: {configureKey: 1},
    configure: async (device, coordinatorEndpoint) => {
        const endpoint = device.getEndpoint(35);
        await bind(endpoint, coordinatorEndpoint, ['genPowerCfg', 'ssIasZone', 'genBasic']);
        await configureReporting.batteryVoltage(endpoint);
        const endpoint2 = device.getEndpoint(38);
        await bind(endpoint2, coordinatorEndpoint, ['msTemperatureMeasurement']);
        await configureReporting.temperature(endpoint2);
    },
    endpoint: (device) => {
        return {default: 35};
    },
},

Hi Koenkk,

I modified the devices.js and now it works. Thank you! Can this be updated in the next release, or do I need to submit a pull request?

The problem:
configureReporting.batteryPercentageRemaining(endpoint);
should be modified to
await configureReporting.batteryVoltage(endpoint);

Added the fix.

Changes will be available in the latest dev branch in a few hours (https://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html)

Hello,
I'm have this exact problem with a new SMSZB-120, zigbee2mqtt running in HASSIO but I cannot find device.js anywhere. Tips on were it is located or should i create the file?
