I have recently migrated from Vera Plus to Hubitat. Overall, I am very pleased with the options and richness of the system. However, I seem to be having some stability issues. When it strikes, I can see the dashboard, but any request to control a device fails. Also, when I go to the local web interface, I can see the devices, but all attempts to control them fail. I am able to navigate across the various pages and reboot the hub which restores service. This might be triggered by an rule I have that monitors the power consumption of my well pump in order to alert when the water has been on too long, and to alert me and ultimately shut down power to the pump.
The involved switch is the GE 14285 Indoor/Outdoor smart switch, which I have used for years. To make it work with the Hubitat, I am using the add-on Z-Wave Metering Switch driver with power consumption as the monitored variable. Unfortunately, it is necessary to have a rule refresh that switch every couple minutes to get the power value. My suspicion is that some interaction between the rules and that switch is causing the issue. I have looked at the logs, but frankly don’t know what to look for.
In the meantime, I am getting a WiFi outlet that I will plug the Hubitat into. I do have a Raspberry Pi with TeamViewer set up to be able to control remotely. My thought is that if the hub freezes and I cannot access it with the Pi, my final recourse will be to cut and restore power to reboot the hub.
Please point me in the right direction and also point out anything in the above that is stupid! I did some searching and did not fine anything that would help. If there is another resource I should know about, please let me know.
It may be your only option but cutting the power is never a great answer. It will sometimes result in database corruption with all the pain and anguish that entails. It looks like you are on the right track to diagnose - I'm not familiar with the switch or that driver so I can only say good luck!
Shut it down again, unplugged for a minute, and it is working again. I changed the drivers for the switches to generic z-wave smart switch and paused the rule that I am concerned is triggering the issue. Since one of the most important uses for my hub is this rule on these devices, sure hope I can figure it out.
Thanks for your response! The switches will return on/off status, but in order to have them report power, unfortunately, they need to be refreshed. So I created a rule to refresh them every couple minutes.
Currently, they are using the generic z-wave smart switch driver and I have the rule that monitors them disabled. I assume I should return to the previous config, wait for a failure and then check?
Thanks. I responded to the message with a couple of images. Looks like I was wrong that those switches/apps were to blame. The damned thing is just failing. Hopefully I can figure this out. This thing seems vastly more unstable compared with the Vera products I have owned, which surprises the hell out of me.
If you did not get the images, please let me know.
Sorry, I don’t know. To the best of my knowledge I did not reset it.
But unfortunately, the hub no longer recovers after a reboot or a shutdown/restart. So, I am trying leaving the hub off for 30 minutes after a shutdown. I suspect after that, I will need to try a factory rebuild and reset or backup. I kind of feel like I am rubbing a lucky rabbit’s foot and hoping for the best. Once again, thanks for your help!
Do you think I should try to restore a backup? Oddly, the behavior started after the hub had run find for quite a while.
And please let me know anything else you think will help or any other ideas before I go through the mind numbing rebuild process!
I would first try generating a backup and immediately restoring it. This can help to clean up issues with the database (if there are any).
If that doesn’t do anything, generate the backup, soft reset the hub, and restore the backup. That can also help to clear up issues if it happens to be a database problem.
