Today none of my flows with sonos worked anymore. The flow indicated “device not available”. none of the devices worked anymore. So checked the sonos app. restarted, and repaired. did not help. I then tried to add a sonos device, and all my sonos devices popped up, i.e. ALL of then had disapeared. I now have all old ones, and the new one, and need to repair all my flows, by replacing the old device by the new one. I find it really strange that this can happen (and it has happend before) any idea how that is possible, and how to ensure it does not happen in the future? I have all sonos devices on a fixed IP address in my router… Strangely enough my HA devices did not have this problem ---

Most probably a restart of your router and access points solves it (next time). I think it’s mDNS related. For repairing flows quite easy, you can use this great script: > [@\[HOW-TO\]\[Pro\]\[Cloud\] - 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. So what do you need: Device ID you would like to update - You can get this via t… ---
