Zigbee2MQTT external converters availible
An external converter is a text file with a description of how to work with one or another ZigBee device if it has not been added to the official support.
You can use the base not only to find your specific device but also as a template. After all, manufacturers have a lot of completely identical functional devices that differ only in the manufacturer’s code. In addition, it happens when the supported device does not have all the functionality implemented and it can be added just through the converter.
