Regardless of whether your BMS is connected with a hardwired ethernet cable today, or connected using WiFi client access, it can sometimes not be obvious or easy to know the initial (dynamically assigned) IP address for the BMS on your local network.
If the BMS is on an Internet-connected network segment, and if you have a computer or smartphone on the same local network segment, you can determine the local IP address of your BMS by just clicking on this URL:
You can also log in using WiFi and check the assigned IP address(es) on the Tools->System Information page in the BMS
Finally, if the BMS is connected to an Internet-attached network segment, the BMS can also be accessed via the Redflow BMS cloud service at https://cloud.zcell.com (contact Redflow for an authentication access to this service if required).
When logged into the Redflow cloud service, any locally-attached BMS units are identified automatically - and the IP addresses assigned are also shown for all BMS units you are authorised to access.
