Hi there, Since a few days my Homey Pro is experiencing a very heavy load, which causes the system to go offline for 5-10 minutes. This happens several times per day. I have enabled the logs and I see many errors saying; 2021-12-24T22:58:43.056Z Command[9759] end: isFailedNode I see one topic of a few years ago, which stated it was an issue that has been fixed by Athom so I guess this is not the same. I have checked all visible nodes and don’t see a node that has a problem. The errors don’t tell me which node it is. Anyone that has an idea what it could be or how to check what the problem is? ---

We’re at about 20 moments per day that Homey goes offline for 5-10 minutes. Seems like the problems are accumulating. If anyone has a suggestion… ---

If you still use the original power supply for your Homey, try replacing it with something better (5V, 2A minimum). ---

It’s not that, unfortunately. That has been replaced a while ago. It’s the “isFailedNode” commands that are increasing by the hour and are overloading the system. Thanks for the suggestion. Maybe interesting; the issue seems to have popped up after the Z-Wave network had to start at the top with numbers again. I have about 140 Z-Wave devices and since Homey for some reason skips numbers randomly it came to 230. The next device got number 6 (unused number) and I think the problems started then. ---

Have you contacted Athom’s support desk? ---

You should at least receive a confirmation and ticket number the same working day. Spam folder? ---

Sure, I got that one. And I have updated the ticket with new information. I meant that no one has replied yet, probably because of the holidays. ---

When it keeps quiet they don’t have an instant solution I’m afraid. Well make really really sure your powersupply delivers 5V / 2A min. Some seem to deliver 4 or even 3V after some time in use. This creates the weirdest problems as you can imagine. _There’s the zwave reset option_, but I can imagine you don’t want to use that with 140 devices in use… You can also try post your issue at the Homey channel @ Slack, Athom devs are somewhat active there ---

Thanks for the suggestions. You are right; a Z-Wave reset is definitely not preferred. 🙂 Most of them are hidden away. I have changed the adapter for a new one yesterday, just to be sure. Unfortunately it didn’t make any difference. I had two of the new adapters, one for another Homey Pro. Allright, I’ll try Slack. Maybe they’ll come up with something there. Thanks!
