On the first view, you have problem with Node71. I would suggest to remove it (remove unknown nodes) and pair it again - you also would need to manually repair your flows, eg. using script (ensure you note down the device ID prior removal) : [[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) Also it’s not clear from your list,which of those devices are NON-battery, so they can act as routers. If you have lack of routers and higher distances from Homey, then issues may arise as Peter mentioned. Als you can try to build ZWAVE map to see or to troubleshoot further. > [@\[HOW-TO\]\[Pro\]\[Cloud\] - Z-Wave Route map](https://community.homey.app/t/how-to-pro-cloud-z-wave-route-map/105763): > > Hi, I saw this [thread](https://community.homey.app/t/mesh-map-of-zigbee-network/91010) and was inspired to create a script which can do this for you. I made 2 variants: [Zigbee Variant](https://community.homey.app/t/104966)[Zwave Variant](https://community.homey.app/t/105763) Instructions: Run this script in the [WebAPI playground](https://tools.developer.homey.app/tools/api-playground): (make sure to empty the text area first) const main = async function () { console.log('Starting main function...'); let state = await Homey.zwave.getState(); let data = await Homey.zwave.runCommand({ command: 'getNetworkTopology' }); let failed = Homey.zwave.runCo… --- _[View the full topic](https://community.homey.app/t/z-wave-unreachable-issues/114365)._
