Ask per site instructions, I did a search on deleting a device and trying to add it back. What I think I found is that it is not possible. I did see a post that made me think I could delete the older (deleted device) installation and start a new installation. Is that true? Any issues in using the same VRM portal number for the Cerbo? I am a rookie and still learning. My system consists of 4 200aH Smart Lithiums, Lynx Smart BMS 500, Cerbo, MultiPlusII 12/3000, and a Smart MPPT controller. I had some issues after an firmware update to the MP2 and thought I could add a device after deleting it.
Thanks for your response.
