I have a device (Aeotec Multisensor 6) that is now shown in Homey as “Device Unavailable invalid\_node”. Anyone know - Why might this have happened - How to recover it (without having to remove/re-install/lose all associated flows)? Thanks ---

Reset the Aeotec App. Check the battery. ---

Thanks I’ve restarted the app, and the exclamation mark and “invalid\_node” still appear. It’s powered by a main adaptor so can’t be a battery issue. Does this error message mean Homey is still seeing the device, but can’t talk with it? Or is Homey remembering there was a device once with that node ID but can’t find it? Or something else? ---

It’s a script to be precise 😉 (apps haven’t got sufficient rights for replacing device ID’s), here’s the link @K_S : > [@\[HOW-TO\]\[Pro\]\[Cloud\] - 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.

(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.

I know this is an old topic. But I encounter the problem in a huge way. I issued a ticket to Athom, because the appreciated solutions above are way too difficult for me and my experience. I hope there are easy solutions for simple users like me who just want a working system and dont have weeks and weeks to rebuild 70% of their Homey? This week I migrated from Pro 2019 to Pro 2023 Besides that a lot of one Zigbee devices were not found, a lot Z-wave devices give errors: Invalid Node xx. At least all 21 Fibaro devices do not work anymore becaus of the node-error Also most zigbee devices were not found. I have no wish or time to rebuild everything including close to 100 flows. Am i the only one? ---

No, as far as I know you’re not the only one with this problem. That’s why I suspect it’s a bug. My recommendation is to switch back to the HP19 and wait to hear what Athom support has to report. Before you switch back to HP19 please read this [post](https://community.homey.app/t/howto-homey-pro-early-2023-migrating-from-homey-pro-early-2016-2019-with-early-access/77516) **first**! Because if you already repaired the Zigbee devices on HP23, you have to re-ad them and repair all your flows. > [@Willem59](#): > > Besides that a lot of one Zigbee devices were not found This is also mentioned in the linked post. ---

Thanks Fantross, I did take all the steps pointed out in the post by Dijker. But: the ‘repair’ option did not work with any of my zigbee devices. And most z-wave devices gave the node-error. I did turn of the Pro 2023 and got back to the Pro 2019 already. So there is a lot to re-add. Homey Pro 2019 runs mostly again. But: now the Aqara and Frient devices did not work anymore. I can’t even add them again to the Pro 2019 😢. 6 devices Hours and hours work and a less working Pro 2019 makes me NOT happy 😞. Ill await what Athom has to say about the matter. On the site I read that this could take weeks. Even less happy 😱. ---

> [@Willem59](#): > > But: the ‘repair’ option did not work with any of my zigbee devices. Hi Willem, this is also a known bug and according Athom support this bug will be fixed in the next firmware update. I was informed about this about 3 weeks ago. But no new firmware has been released since then. Just for info, these are some threads according this bug: > [@Reparatur von Zigbee Geräten nach Migration vom HP19 auf den HP23 nicht möglich](https://community.homey.app/t/reparatur-von-zigbee-geraten-nach-migration-vom-hp19-auf-den-hp23-nicht-moglich/86315): > > Nach der Migration vom HP19 auf den HP23 (FW v10.0.1-rc.1) mittels Backup, ist es nicht möglich die Zigbee Geräte zu reparieren.

I can’t even add them again to the Pro 2019 😢. 6 devices If you didn’t re-add the Zigbee devices on the HP23 because repairing doesn’t work, then you don’t really need to re-add the Zigbee devices on the HP19. After starting HP19 again, all devices should be present and should be work. To add the devices again, try the following: – Restart the Aqara and Frient app – Restart Homey – [PTP](https://community.homey.app/t/how-to-ptp/17304) ---

Thanks for your help Fantross, I tried to readd the devices on the Pro 2023 after repair did not work (and before I noticed all Fibaro’s did not work either). But yesterday late I got them working on my Pro 2019 again. I deleted the Aqara and Frient aps from my Pro 2019 and reinstalled them. After restarting the Homey, the Frient’s and Aqara’s could be added again. Repairing the flows was a bit of a nuicance: but my printscreens of the flows helped with that. Your message of the upcoming firmware gives me hope. Thanks. Do you think that could also reair the nodes-problem with z-wave on the 2023? ---

Good to hear, that HP19 is running again. I also take screenshots of my flows. 👍🏻 > [@Willem59](#): > > Do you think that could also reair the nodes-problem with z-wave on the 2023? I hope, but I don’t know. After I migrated from HP19 to HP23 I had no problems with my Z-Wave devices, also not with Fibaro devices (40 pieces). I observed the Z-Wave Network about 2 days and I didn’t recognized also no problems with the “too much traffic” issue. So I’m not in contact with Athom support regarding these Z-Wave issues. **Edit** @Willem59, today a new experimental firmware ([Changelog](https://homey.app/en-us/wiki/homey-pro-early-2023-firmware-changelog/)) with many fixes for Zigbee has been released. ---

THANK, and yeah, i noticed. I am happy… Nothing about Z-wave, I saw. Does anyone know if the Pro 2023 has a repair option for Z-wave too (like Zigbee)? I forgot and -as I am running the 2019 now- i cannot check it quickly. Might be handy to have that for z-wave too? ---

There is node by node (ie 1 at a time) “heal” option at [Homey Developer Tools](https://tools.developer.homey.app/tools/zwave), which sometimes works. “Reset” lower down that page is the nuclear option. **You’d have to re-pair / install every z-wave device.** (Homey doesn’t have anything like the Fibaro controllers, where the repair attempts to re-optimise the entire z-wave mesh network in a non-destructive way)
