Not (yet) supported in zigbee2mqtt about z03mmc

[devbis]

Yes, it is not in the repo, but I'll add it soon.

const fz = require('zigbee-herdsman-converters/converters/fromZigbee');
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const ota = require('zigbee-herdsman-converters/lib/ota');
const e = exposes.presets;

const definition = {
    zigbeeModel: ['LYWSD03MMC'],
    model: 'LYWSD03MMC',
    vendor: 'Xiaomi',
    description: 'Temperature & humidity sensor',
    fromZigbee: [fz.temperature, fz.humidity, fz.battery],
    toZigbee: [],
    meta: {battery: {voltageToPercentage: '3V_2500'}},
    configure: async (device, coordinatorEndpoint, logger) => {
        const endpoint = device.getEndpoint(1);
        const bindClusters = ['msTemperatureMeasurement', 'msRelativeHumidity', 'genPowerCfg'];
        await reporting.bind(endpoint, coordinatorEndpoint, bindClusters);
        await reporting.temperature(endpoint);
        await reporting.humidity(endpoint);
        await reporting.batteryVoltage(endpoint);
    },
    exposes: [e.temperature(), e.humidity(), e.battery()],
    ota: ota.zigbeeOTA,
};

module.exports = definition;

Thank you for the converter, it is now recognized in zigbee2mqtt although humidity value seems not (yet) reported?

I also checked with the z03mmc_heiman firmware and is also not reporting the humidity value?

[devbis]

Both values are reported. Check temp and humid clusters are bound in zigbee2mqtt tab. And rebind if checkboxes are different.

You may also try to use binaries from https://github.com/devbis/z03mmc/releases/tag/2023-10-08

[Ctrl-F4]

Checkboxes are same as yours. Tried to rebind, rejoin, reflash but no humidity readings. Downloaded your precompiled fw and no change . Tried to sniff the data with wireshark but found no data for humidity.
Don't know how to debug further.

[devbis]

Can you read values from the cluster with dev console in zigbee2mqtt for a device?

[devbis]

Please, check firmware from this run: https://github.com/devbis/z03mmc/actions/runs/6455005642
It has increased number of items for reporting and binding and it could help.

Yes this works! But value not updated automatic. Not yet tried the test fw (6455005642)

Same behaviour for this fw ( uploaded z03mmc.bin). Via dev console forcing humidity readout, it shows same value as lcd. Then increase temp and humidity at the same time only temp reading is updated.

What's on the reporting page? Is humidity configured? Does remove and and set back change anything?

[Ctrl-F4]

Yes humidity is on the reporting page. Disabled all items and reconfigured the device again so all the items are repopulated on this page. Made no difference. Maybe try a new z2m install with new coordinator later this week.

I have the same parameters and it seems reporting well (though I'm not 100% sure). I'm testing on zigbee2mqtt 1.33
What hardware revision do you have? You can read it from genBasic cluster in z2m

[Ctrl-F4]

Read result of 'genBasic': {"hwVersion":14}
zigbee2mqtt 1.33.1-dev commit: 2aae1bd5
zStack3x0 Coordinator revision 20230507 (CC2652P Sonoff ZBDongle-P)

If you need more information let me know, ready to test.
(In the meantime i have to find out how to set up OTA for convenience)

[devbis]

Can you please try the latest pre-release? It is build with updated SDK and may fix reporting issues.

[Ctrl-F4]

Yes it started reporting humidity with this new fw!
I'm curious how long battery will last in comparison with the ble fw. (when configured same reporting interval)
Thanks again!

[devbis]

I don't have long-lasting results with a battery, but the expected working time should be approximately the same as with bluetooth firmware.
