1. Go to Zigbee2MQTT directory which contains configuration.yaml file

3. Add the folliwing lines to configuration.yaml:

ota: 
    zigbee_ota_override_index_location: my_index.json 

(you can use any file name instead of my_index.json))
4. Create my_index.json (or your chosen filename) and add the folloowing strings to it:

[
    {
        "url": "1141-0203-10023001-z03mmc.zigbee"
    }
]

(Use the actual file name)
5. Restart Zigbee2MQTT from its web interface

You'd better ask SLS team for it. I suppose OTA is not a supported feature there, but it's better to double-check it

Have you tried updating LYWSD03MMC by yourself using this method? (I'm guessing that not only have you not tried this, but you haven't even read the description of this method :-) ).

Don't judge by yourself. I successfully updated from 1.0.1 to 1.0.2

I just update to new version using Zigbee2MQTT using the OTA menu without any issue.

I have SLS gateway and mosquitto broker - how can I do the upgrade procedure?
