Tuya TS0042 - no battery

[Mr-Groch]

What happened

Tuya TS0042 device does not send battery values (no voltage and no percentage, but battery is exposed). As can I see in device clusters it should support battery information:

I think this is related to #6180 - same device family, but with 2 buttons...

What did you expect to happen

Battery level should be reported

How to reproduce it (minimal and precise)

Just pair it and observe no battery values

Debug info

Zigbee2MQTT version: 1.17.1-dev commit: 8eb1a98 Adapter hardware: CC26X2R1 zzh! Adapter firmware version: 20210120

After adding this to devices.js, and after z2m restart battery percentage is sended, like in #6180:

    {
        zigbeeModel: ['TS0042'],
        model: 'TS0042',
        vendor: 'TuYa',
        description: 'Wireless switch with 2 buttons',
        whiteLabel: [{vendor: 'Smart9', model: 'S9TSZGB'}, {vendor: 'Lonsonho', model: 'TS0042'}],
        exposes: [e.battery(), e.action(['1_single', '1_double', '1_hold', '2_single', '2_double', '2_hold'])],
        fromZigbee: [fz.tuya_on_off_action, fz.battery],
        toZigbee: [],
        meta: {configureKey: 1},
        configure: async (device, coordinatorEndpoint, logger) => {
            const endpoint = device.getEndpoint(1);
            await reporting.bind(endpoint, coordinatorEndpoint, ['genPowerCfg']);
            await reporting.batteryPercentageRemaining(endpoint);
        },
    },

Added your changes. thanks!

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)

@Mr-Groch hi, sorry i don't mean to revive an old thread, i was wondering what is your battery life on these devices. I have 4 of them and they die pretty much every 3 4 weeks with little to no use. The devices keep announcing themselves once every hour too, which might be why they drain. I would appreciate somw feedback. Thx

Le. I actually mean the ts0041. I posted in the wrong thread, but i now you added support for both of them

[Mr-Groch]

Yes, I had same problem with draining when reporting was enabled for those devices (by default). You must manually disable reporting (you must press the switch before clicking on reporting remove button). I've replaced baterry few months ago and no draining now.

Hi, thanks for coming back to me. Really appreciate it :)

I am just wondering if instead of removing reporting, which will lose the battery status altogether, it might be worth altering the reporting period. Maybe sometime like min 0, max 0, change 1 (maybe even 5).

According to spec this will only report on value change and not on time interval

For me the device fails to change the reporting values and even completely remove the binding from the Frontend, so I guess i shall run some tests on my testing instance changing the reporting in the code.

PS: my device is the Zemismart one

Hi! I have the same reporting problem, is any update about that?

You will need to be a lot more specific than this.

On the latest version of z2m there are no reporting issues. The device is not meant to do reporting, instead it will expose the value from time to time. If you updated recently you will need yo re pair your device to ensure it configures correctly
