Hub process slowdown after several days

🛎️ Get Help
21

I'm watching this thread with interest. I experience a slow down every couple of days, and only a reboot will help. But a reboot does make everything snappy again.

I don't have a system that's all that big: 11 Hue lights via a Hue Bridge, 1 lock, 2 contact sensors, 6 motion detectors, a couple of buttons, 1 GE z-wave plus switch, a handful of pocket socket repeaters, some Aeotec extenders, a bunch of virtual devices for various automations, my "friend" Alexa, Logitech Harmony. That's about it.

1 Simple Lighting rule, 1 Motion Lighting rule, a dozen or so RM4 rules.

User apps: Average This, Reliable Locks, Super Tile. At one time or another I've tried disabling each of these. It didn't help.

User drivers in use: SuperTilesDisplayDevice, Reliable Lock Virtual Device, Logitech Harmony Hub Parent, HTTP Momentary Switch, the new DarkSky.Net Weather Driver, and the Logitech Harmony Hub Parent and Child Switch.

I was using Botched1's GE Embrighten Z-Wave Plus Switch driver, but at one point I changed my GE switch back to the generic z-wave switch, just in case that was what was causing the slow downs. It doesn't seem to have made a difference.

As someone else noted above, it mostly seems to be my RM4 lighting automations that slow down, to the point that I'm well into a room -- sometimes for a while -- before the lights come on.

I've tried deleting various user drivers. I've tried disabling some virtual devices. I've tried splitting up my RM4 rules to make them simpler. I've gotten rid of all global variables. I've added in private booleans and exits by mode to keep rules from running when they don't need to. None of this has made any difference.

Don't know where to go from here other than to keep rebooting. I've set up an RM4 rule to automate a reboot in the middle of the night.

What’s your rule look like that reboots the hub?

I'm very similiar to you. Slowdowns every 2-3 days. I have a two hub system, and my main hub (C5) is the hub that slows down. I've removed most of the iffy devices to my second hub (C4) which has no issues.

Devices              Main (C5)    Client (C4)
 Sonos               Yes          Yes
 Hue                 Yes          No
 Network alarm       No           Yes
 Network TV          No           Yes
 TPLink integrations No           Yes
 Apixu Weather       No           Yes
 Yealink             No           Yes
 Iphone presence     No           Yes
 Dashboards          Yes          No
 SuperTile           Yes          No
 Average All         Yes          No
 Zwave devices       Yes          No
 Zigbee devices      Yes          Yes

I know it's better to have the zwave devices on the client hub, but I have not yet had time to move them. I run two zigbee neworks to keep my Xiaomi's away from problematic routers. The zigbee networks are on different channels, and also different to the Hue hub.

All devices on C4 client are mirrored to the main C5 hub with Hubconnect using websocket. Yet, it's the C5 hub that has slowdowns!!! Frustration plus. Even loading the device pages is slow after a 2-3 days. The speed difference is obvious between the C5 (slow) and C4 (fast) when loading apps, devices, and settings. I notice that my lighting rules are sluggish after 2-3 days. It can be to 5 seconds into the room before the lights turn on. A reboot fixes the issue. I'd really like a fix. Local processing is no good if it's this slow after 2-3 days.

I have no evidence of this, and just thinking out loud, but could it be the Hue integration? It seems to be a constant above with reports of slowdowns?

Edit: my two HE hubs sit next to each other, literally on a cooling fan (Australia). They are connected via Ubiquiti Unifi switches. My mesh are great. I have XBee mapping.

You should look at this thread as it seems to have fixed my problems. BTW I also have Hue integration Hubitat web is VERY slow. It defeats the benefit of local processing

25

Yeah, I've posted in that thread, but had no responses. I use Ubiquiti Unifi products, not Asus.

26

Same here, I don't think this particular issue has anything to do with networking equipment - I contacted Bobby and he said my Netgear switch should not be affected. Besides network issues don't explain why logic processing on the hub is slow.

27

I also experience the slowdown over several days and a reboot seems to speed the rules back up. I have 2 HE's with 1 hub with all the Zwave and Zigbee devices and the second hub with all the cloud connections like Rachio, Hue, Sonos. I made this move hoping that cloud connections were the problem but I didn't notice an improvement. I have avoided a bunch of the third part apps and drivers to try and avoid any poorly written drivers that might drag the hub down.

28

I'm not using Netgear nor Asus, and my dashboards are actually usually pretty zippy.

It's my lighting rules that drag. I'm wondering about Hue as well, since that seems to be a common thread. I'd hate to delete my Hue, though. I can't do the kind of automations I want in the native Hue app. Complex automations were one of the features that sent me to HE.

29

I have Hue as well and No issues going on 48 hours, which might be a record as I was rebooting daily for a while. I had NST Manager and uninstalling that made a big difference. I also disabled several TP-link lights and plugs. I have read that unresponsive lan devices can crash the hub, like wifi lights and other integrations.

30

I have found the built in Ecobee app or for that matter any Ecobee app installed on HE slows down the hub. Not sure if anyone experiencing issues is using the app.

31

I dont use Ecobee, so not that for me.

Here's the rule

reboot

I'm having slowdowns so bad it's taking up to 2 minutes to trigger a light switch via the portal or sharptools. It's unusable right now. This just started about two weeks ago for me. Been running it fine for about a year with no changes in the past 4 months

34

No NST, TP-link, or Ecobee here.

35

I also went through all if my device pages and discovered that they were still showing up as being in rules that they had been removed from. As in opening the rule showed they were not there. I ended up deleting and rewriting a lot of rules, which may have been an issue. I also removed most of my scenes and just created rules for them. I also had several null devices in the zigbee routing page.

36

Just a thought.... do you guys have older rules than 4.0 still in operation ??
Changed all mine over last the weekend (thx @denise.grider) :slight_smile:

It might be another thing to explore !

All of my rules are RM4. I changed them over pretty soon after RM4 was released because I like it better than RM3.

I don't use a lot of scenes, and what I do have are usually triggered by RM4 rules twice/day. Rarely I have another couple of rules that might be triggered a couple of times per day.

I don't have any null devices.

I think I saw in another thread that someone -- Bruce, maybe -- said that the leftover rules showing up on the pages of devices that were no longer in the rule don't really hurt anything. I haven't tried to do anything about those.

38

All RM4 here. the only integrations using LAN are Sonos, Lutron, HubConnect, and Hubduino on my main hub, which seems to be having the slowdowns. Tried disabling all and it had no effect. I am thinking that there is something about RM4 hanging onto resources, or a process not releasing resources, such as logs, and as the resources disappear, the hub slows down. Not sure, not really my forte, but seems plausible! lol

39

All RM4 here too. I dont have any chromecasts either. That has been a problem in the past, from memory.

I do have Google home on my main hub, and it's been faster than me pulling out my phone, opening a dashboard (and waiting) and pressing a button.

Hmm Ok, that pretty much rules out old rules conflicting with RM 4.0.
FYI I'm also pure 4.0 and do not experience any hub slow downs and have only ever rebooted my C4, twice in more than 12 months. Those times were to rewire or for a planned system change.
I've also just got the single Hub and have beta Chromecast doing TTS to a single GoogleHome Mini.

It's been a good while since the HE guys pushed out a release so perhaps there's a big rolled up version in the wings ?
