Hello,

Sorry for my English.

I have a proposal for a modification to add a reset command for the counters of the OWON PC321 clamp meter.

Thank you in advance.

Attached is the modified code (you need to replace .txt with .js.): PC321.txt

The modifications :

const tzLocal = {
    PC321_clearMetering: {
        key: ['clear_metering'],
        convertSet: async (entity, key, value, meta) => {
            const endpoint = meta.device.getEndpoint(1);
            const group = 0xFFE0;
            const command = 0x00;
            const payload = {};

            await endpoint.command(group, command, payload, {disableDefaultResponse: true});
            meta.logger.info(`Sent clear command to ${entity.ieeeAddr}`);
        },
    },
};

toZigbee: [tzLocal.PC321_clearMetering],

e.enum('clear_metering', ea.SET, ['Clear']).withDescription('Clear measurement data'),
