 If the script stops with the message `dbus.exceptions.NameExistsException: Bus name already exists: com.victronenergy.grid.mqtt_grid"` it means that the service is still running or another service is using that bus name.
 
+### Multiple instances
+
+It's possible to have multiple instances, but it's not automated. Follow these steps to achieve this:
+
+1. Save the new name to a variable `driverclone=dbus-mqtt-grid-2`
+
+2. Copy current folder and add a number `cp -r /data/etc/dbus-mqtt-grid/ /data/etc/$driverclone/`
+
+3. Rename the main script `mv /data/etc/$driverclone/dbus-mqtt-grid.py /data/etc/$driverclone/$driverclone.py`
+
+4. Fix the script references for service and log
+    ```
+    sed -i 's:dbus-mqtt-grid:'$driverclone':g' /data/etc/$driverclone/service/run
+    sed -i 's:dbus-mqtt-grid:'$driverclone':g' /data/etc/$driverclone/service/log/run
+    ```
+
+5. Change the `device_name` and increase the `device_instance` in the `config.ini`
+
+Now you can install and run the cloned driver. Should you need another instance just increase the number in step 1 and repeat all steps.
+
 ### Compatibility
 
 It was tested on Venus OS Large `v2.92` on the following devices:
