I have a couple of performance-related concerns. When I make a simple lighting rule, it doesn’t seem to work right away. If I walk away, and come back in 5 minutes or so, it’s fine. Is there a recompilation or something that’s happening in the background? I just want to know what to expect.
I also seem yo be having some zwave concerns/lag. I use zigbee sensors, and zwave switches. I also have zwave buttons. The zigbee motion sees me (it flashes), and the zwave doesn’t always respond immediately; or sometimes there’s a major lag. Also, same with the button. What might be the likely culprit? Suggestions?
In my experience, Z-Wave motion sensors are just categorically slower than pretty much any Zigbee sensor. You can narrow down device vs. app by checking live logs as you trigger things (or digging through past logs after the fact)--the idea would be to see when your sensor reports motion compared to when you think you should have set it off and when the lights actually turn on (enable logging for you app and devices too to help).
I'm not sure what buttons you're using, but some seem to go to deeper sleep if they've been dormant for a while and take a few seconds to return to normal. Whether it's them rejoining the network behind the scenes or finding/verifying a mesh path or something, I don't know. I haven't used enough Z-Wave buttons to see how they fare but can't imagine it's much better. Logs may again help narrow it down. If you have a SmartThings button, making sure it's on the latest firmware may help.
I’ve been paying close attention and have noticed some things —
The motion sensors don’t always pick up the motion immediately. I’m ok with this. It’s not perfect; but definitely good enough.
I definitely have zwave problems. Definitely. I’m using GE zwave plus dimmer switches. I’m using the custom driver to give me double tap functions. There are multiple automations when motion {zigbee} (or other automations..) that I have turn on 2 switches. The lag between one switch coming on and the other is seconds. Sometimes they both lag out, not coming on for seconds. The logs have the “on” time for both switches being identical. So to me, it’s a zwave issue. Those logs are the time that the on command was sent.
I have run zwave repair. It has not seemed to fix things (4 days ago).
You could disable apps / child apps to find out what is causing this. There is this very handy function in the app list right top of the screen, next to the grid view icon, X. It gives you the ability to easily and quickly disable apps.
I don’t think it’s an app; I am just getting started. This lag is all I’ve known since I started with 3 switches/dimmers and some basic simple lighting automations. I now have 10 switches or so moved over from SmartThings.
I know somethings wrong when the cloud performance on ST was as good or better than Hubitat. That’s not the experience others had, nor what I expected. Somethings just not right.
My hub is sitting right next to my AP, on top of a server inside my furnace room. I didn’t have to do that with SmartThings, because ST had WI-FI built in. Would this be an issue?
Heat could definately be an issue. You can get the hub out of the furnace room (recommended. All that metal isn't doing you any favors with your Zigbee and Z-Wave signals), by using Powerline adapters to convert your powerlines to carry ethernet from the furnace room, to the hub in a better location.
You may also have a device that is misbehaving. If Z-Wave it could be that one or several of them didn't properly exclude from the SmartThings hub. You should try an exclude, then factory reset, then include to Hubitat. If Zigbee, it could also be a channel conflict with SmartThings. Check what channel ST is using, then change HE to something a few channels away to there is enough separation.
Also, keep in mind that when you first install devices, the hub is very busy building the mesh. You wouldn't have experienced this with SmartThings, because you most likely added devices one at time or just a few at a time. You probably didn't sit down with several devices and connect them all to the ST hub within a few minutes, hours or even days, so the mesh had time to find the bast parents and establish a strong mesh network.
