For the past few weeks whenever I give my Echo a command for SmartThings or try to send a command in the app there’s a serious delay. Sometimes as long as 5 minutes. Also, some of my morning routines will sporadically not run.
I’ve restarted the hub and it worked great for a few hours, but then it’s back to it’s delay. I’m not even sure how to troubleshoot this.
Can you determine if only a particular protocol is having issues? Ie: Z-wave vs. Zigbee devices?
I would recommend you open a ticket with ST support.
I know it’s Zwave. I’m actually not sure I have any Zigbee devices.
Have you tried a z-wave repair? And did you monitor it until it completed successfully?
I did the Zwave repair, monitored it to completion and I think it made stuff worse. I have several devices that will say they are unavailable and then an hour or so later, they are available again. Support suggested I clear the app cache and even reinstall the app (which I did). I also restarted the hub.
I timed it out and there’s a 3 minute delay. Even on commands that don’t go through the app (e.g., I have a smart switch that all it does is turn on a different smart switch and that took 3 minutes. It used to happen within seconds).
Any other ideas on what to check?
Brand and model of those two switches? And are you using the official smart lighting feature or something else to tie them together?
I’ll have to look when I get home. The problem seemed to resolve itself, but it’s happening again. Support keeps telling me to uninstall and reinstall the app (which I’ve done). I have it all done through the smart lighting feature.
My automations are event acting up. I have an ‘Evening’ automation set to run at 10:00 every night, about once a week that won’t run. I also have a ‘Good Night’ automation that we activate manually through our phone or a button on an Aeon remote, that will also take a few minutes before it actually executes.
As far as routines, there are known issues when you have too many actions in one routine where it will just time out before everything gets accomplished.
I would suggest limiting anyone routine or automation, including a smart lighting automation, to no more than 10 individual devices and preferably six.
If you only want to have one trigger, you can daisychain these, so that the first routine turns on a virtual switch which triggers the second routine and so on. But it’s pretty clear that SmartThings just is not designed for high volumes in any one automation.
These are simple automations that only have 4 or 5 devices in them. I’ve had them set up for a few years without any issues, all this trouble started recently.
I’ve been debating whether it’s time to jump ship from ST, but I don’t know where to go and being able to continue using all the devices I have is obviously a requirement.
Understood. Unquestionably the most frustrating thing about a SmartThings platform is when you have something which is worked great for months or even years and then it stops working.
I am facing this with the intentional removal of a feature which was the whole reason I came to home automation in the first place: hands-free operation of a smart lock. unquestionably the most frustrating thing about a SmartThings platform is when you have something which is worked great for months or even years and then it stops working.

As far as where else to go, different things work for different people. And it depends very much on which exact devices you currently have. You can find a number of conversations in the forum about various options. Here’s a recent one:
