I have 2 Dell OptiPlex 5040 with i5-6500 processors and 6.5.5-arch1-1 that no longer properly shutdown or reboot. The power LED remains lit until the power button is held for 4s or longer but the system is off for all practical purposes. This issue *may* have started with the 6.4 kernel. Several other older Dell models still behave normally so it seems to be processor-specific.

After fiddling around with similar problem with my amd driven pc, I found a possible solution, that works for my box. In my case it was the watchdog. After disabling the module via adding a "modprobe.blacklist=sp5100_tco" to the options line of the bootlaoder,
reboots and shutdowns behaves now as they should be. In your case, with the intel setup, the option entry should, as far as i know, look like this "modprobe.blacklist=iTCO_wdt".

I had the similar problem after updating to 6.6.1-arch1-1. No proper/consistent shutdown and suspend. Switching to the LTS kernel solved part of the problems, but added new ones (e.g. glitches after waking up from suspend). But it turned out that the problem was in my motherboard (asrock z370 pro4 ). I have updated the old motherboard firmware (never updated it since I bought it in 2017) and then reset all motherboard settings, now suspend and shutdown works perfectly on the new kernel.

But now I am getting sporadic errors in Flows where functioning items become Unavailable, I have not figured out how to determine exactly what is unavailable quickly so each broken flow takes some examination.

I only have to reboot my Homey Pro if it is updated with a new firmware and after the restart not apps have started well.
Normaly it needs no reboot.
Not all the apps I have are very busy but I have 47 apps installed.

Like Arie already wrote, this is really not much. Currently I have about >500 flows in use.
BUT, that Homey can become sluggish is mostly not depending on the amount of the flows. It could depend on how the flows are build. If all 10 flows are started every second this is of course a higher load on Homey than if 100 flows are started only every now and then.

I built the zwave network the same as my zigbee network, first by adding 20 mains powered devices that also double as relays, positioning increasingly further from Homey until the extremities of my home are covered. Once stable add battery devices.

I was experiencing intermittent issues with zwave devices I was advised on the Homey Forum that the issue was related to the zwave devices being added as secure by default. To fix the problem I had to remove zwave devices off Homey and re-add them using a community app that forces the zwave devices unsecured.

I originally planned on using Homey as the main hub for house, but in order to get it stable I have not got past the basic roll out of mains powered devices, and I am taking the zwave devices off it to reduce loading so it can focus on the things it is doing really well.

I would love to see Homey stable and trusted, I am confident I can achieve it if I remove Hue from the equation, but that involves spending another 4K to replace it, or just not have the Hue lighting/sensors on the Homey hub, but that would reduce Homey functionality substantially.

What vendor zWave devices do you have? I have a good lot of z-wave devices, mostly Fibaro, a couple of Aeotec heavy duty smart switches and one Aeotec multi sensor, and I never have any z-wave problems.

Absolutely agree Phone charger not good for the Homey, so was using an Apple iPad Pro charger, 3A, they tend to be of a good quality.
Once it was clear that the supplied power supply was insufficient I replaced it in consultation with Homey Support.

As documented I am removing the wave devices. I do know that the Atom Hue App is problematic as reported by Homey Support, one of the Flows is just about managing Apps that consume too much memory. I suspect if I remove the Hue App the Homey will be much more stable, but not having access to all my motion sensors, temp /Luminance sensors and all my lights is not really viable.

There are certain issues which indicate a need to reboot and not doing so can cause longer-term problems. There are also times when you definitely should reboot to ensure things like software updates apply properly.
