> [@Emiliano\_Quetimporta](#): > > If I add the device manually again without removing it first, will it be replaced and all flows keep working out will it be recognized as a new device and have to fix all the flows? During the pairing process of Z-Wave devices, they are automatically removed from the Z-Wave controller in the first step (first green check mark) and then added as a new device in the second step (second green check mark). Therefore you have to repair all flows afterwards. Even though there is a script by @martijnpoppen that makes it much easier to repair advanced flows ([link](https://community.homey.app/t/how-to-pro-cloud-tool-to-fix-advanced-flows-after-removing-and-re-adding-devices/65018)), I would like to ask you to contact Athom support first because of this issue. --- _[View the full topic](https://community.homey.app/t/zwave-no-ack/117561)._
