I’ve been running a Z-Wave network with five pop thermostats and three switches for quite some time now, and it’s been working perfectly. However, after about 18 days of smooth operation, I started encountering I/O errors with the Z-Wave stick. The errors would appear sporadically, causing the system to crash, and the only temporary fix was to reboot the service or the entire system. This was quite frustrating, especially since the issue would return within a few hours of each reboot.
After some research and troubleshooting, I discovered that the problem might be hardware-related. My setup uses an Aeon Z-Wave stick plus on a Raspberry Pi 3 with Raspbian 2.1.0-1. I considered the possibility of switching to a different device to host OpenHAB, but I’m not sure if that would resolve the issue. For now, I’ve been relying on a fresh installation to keep things running for a few days at a time, but it’s not a long-term solution.
I’m curious if others have experienced similar issues with Z-Wave devices and if there are any recommended troubleshooting steps or hardware alternatives that have worked well for them. If not, I might have to look into upgrading to a Tado system for heating control, though I’d prefer to stick with OpenHAB for consistency across my smart home setup. Any advice or shared experiences would be greatly appreciated!
Here’s a snippet of the error logs I’ve been encountering:
2017-10-31 09:25:40.068 [ERROR] [ing.zwave.handler.ZWaveSerialHandler] - Got I/O exception Input/output error in writeArray during sending. exiting thread.

If anyone has successfully resolved similar issues, please share your approach. It would be fantastic to find a reliable solution without having to switch systems entirely!
