+# ZigBee2MQTT: config files
+Extension files for ZigBee2MQTT; only one of the files is required for device support.
+Extract the file into the `/data` folder. Add the following lines to `configuration.yaml` file in the same folder:
+```
+external_converters:
+  - Winner_ZigBee_Basic.js
+```
 
+## Winner_ZigBee_Basic.js
+Basic support for Winner. Available fields:
+- Valve position: open/closed
+- Alarm status
+    - Because of the device's firmware, you cannot turn the alarm on
+- Cleaning mode status
+- Battery charge level
+- Error code
+
+## Winner_ZigBee_dev.js
+**Works the same way as Basic version.**
+
+A version with the full list of the device DPs. Additional DPs will not work with Z2MQTT because of their non-standard implementation: you would need to write additional code for Z2MQTT libraries to properly parse the incoming data.
+
+E.g: any `sensor_*` DP is a 4 byte integer:
+```
+0xAA_AA_BB_CC , где:
+[AA_AA] - bit flags
+[BB]    - signal strength
+[CC]    - battery charge
+```
