In the same developers tool, go to Tools - ‘Devices’, and try to find the removed device here. When found, hit the bin icon on the right to remove it. > [@Adrie\_van\_Uden](#): > > I can use reset Zigbee network, but all devices will be unavailable and I assume all devices should be repaired again. Is my assumption correct? Yes, but your devices have to be paired again. Repair isn’t possible, while Homey sees them as new devices. And the flows used with these devices have to be fixed.

When you have many flows to fix, there’s a neat script which can replace the device ID’s with the new ones BUT you’d have to know the exact ‘old’ device names, and you’d name the ‘new’ devices slightly different. > [@\[HOW-TO\]\[Pro\]\[Cloud\] - Tool to FIX (advanced) flows after removing and re-adding devices](https://community.homey.app/t/how-to-pro-cloud-tool-to-fix-advanced-flows-after-removing-and-re-adding-devices/65018): > > rotating_lightwarning Use at own risk! warning rotating_light Hi, So I just go a new house and wanted to make my Zigbee network a bit better by removing an re-adding my devices so I get a stable network. But the issue with this is you have to fix all your flows. (Ofcourse [Flow Checker App for Homey | Homey](https://homey.app/a/com.athom.flowchecker/) can indicate the broken flows) I made a small script which can help with fixing the flows.
