Hubitat C8 Unresponsive, C8 Locked Up, C8 Frozen,

My old C-7 became the heartbeat monitor. I set things up so that it'll do a power cycle if the C-8 is not pingable. I also have the C-8 shut itself down and then have the C-7 do the power cycle, for certain things like a Z-Wave crash or prolonged Zigbee outage. The C-8 reboots itself if memory goes low.

This is all theory, because it hasn't tripped yet. :slight_smile: Although, I do use it when I want to do a shutdown/power cycle just for the heck of it.

Anyway, I think it's potentially a good use for an old hub. Rather than just sitting in a drawer, it's still in the fray. :slight_smile:

I was thinking the same thing. Nice to know that you did it and made it work. It makes sense and it keeps the automation up and running. Thanks!

Is this true regardless of platform? I never had any issues similar to this running SmartThings.

If Iā€™m hearing you right, in order to keep your C-8 responsive youā€™re using a C-7. I was reading elsewhere that a power cycle is not the best way to deal with an unresponsive Hubitat unit as it could cause Database corruption. Are you rebooting it from the software or turning it off/on again?

I like the creative work around to your solution but it doesnā€™t help people who donā€™t also own a C-7 and C-8ā€¦

What are your thoughts with Joeā€™s predicament? Maybe my set up is screwy because of devices, what would next steps be for him? Just trying to find solutions..

It's never been used in anger.

As I said, I would hope that most times the C-8 would sense something is wrong, and act accordingly first...if it can. So, if Z-wave crashed, it can do a safe shutdown, and then send a command over the lan to the C-7 so that it can do a power cycle (via a ZEN17 relay) of the C-8. If the C-8 doesn't respond to a ping on the lan, I'd say there's not much choice other than to do a power cycle.

Yeah I agree, I havenā€™t found a solution to an ā€œunresponsiveā€ C-8 other than power cycling, but sucks knowing that doing that potentially could corrupt the database, hope thereā€™s a fix for it.

Can you please pick a topic and stick to it? It's easier to follow your issue on one thread. Also, see my private message.

yes for that reason i removed all my sylvania bulbs.. and replaced with hue bulbs on my hue hub.. the only sylvania ones i have left are the gardenspots as there are no similiar replacements. they dont really fx as repeaters as they are on the perimeter and nothing luckily picks them up for the most part.

but it never hung my hub c7 or c8,, they would just not respond and drop off the mesh every so often and were acting as repeaters so screwing a few other things up.. it was a pain to get a chair or ladder and get up there to unscrew and screw back in the bulbs which would reset them.. thus the replacments.s

Did the same years ago. If I remember correctly @King was doing it about the same time I've done it, back in the old days (I mean platform).

I've not had issues with my bulbs, it's really just the C-8 Hubitat itself becoming unresponsive. I haven't had many issues with devices tbh.

You gave up on Hue?

I never had Hue, only SmartThings WiFi (all in one device) and it worked with all my devices, I just switched out because the WiFi speeds were slow really slow, didn't get what I was paying for it.

not a final solution but if you are dead set on using wifi, you could get a cheap tplnk wifi to ethernet adapter .. like 20 some bucks on ebay and 30 some on amazon and see if that alleviates your lockups with wifi.. i have 4 of them on my apc ups in various locations where my wine fridges are so i can monitor them..

and have had good luck with them.

I don't think that works with the c8

it works with anything that has an ethernet port. it works as a ethernet adapter.. connects to your wifi and you connect to your device via the ethernet port with a rj45 cable. he would bypass the wifi and either set a static ip or use dhcp passed through it.

it basically allows you to hook up devices (that have no wifi and only rj45) like my apc ups with smartcards in locations where you otherwise would have no wired internet access without running cable.

basically a cheap access pt.. so obsiously you could also put an expensive router in that location in access pt mode and have it serve the same purpose..

I'm not dead set on using WiFi but when I've tried to use it plugged it kept DC'ing. I went to WiFi using a DCHP reservation and it dropped less but it still had it's issues. I'd like to use it on WiFi otherwise it lives in my basement next to a my main AX6600 router.

I was thinking about the usb tplink adapters not the transceiver type adapters

Curious are you using the oem adapter or something else?

Sorry not following, oem power adapter? Current set up is pretty simple using all the parts that came with the Hubitat.
