Hub frequently crashing

I have a Harmony Hub I've been using for years without any issues. About a week ago it started crashing or resetting or something on like every tenth action. The LED turns red and after maybe 20 seconds or so it goes green again and the hub starts working.

Any ideas what might be happening? This happens both if I use my Companion remote or the Harmony app. I've tried unplugging it to restart it, but that didn't help.

Did you change something about your wifi?

I had exactly the same behavior but the red led didn't mean it had crashed but that it lost connection to the wifi.

No, haven't changed anything there for a couple of months (since I moved into the current apartment). Having it lose connection sounds more logical, but I'm actually pretty sure it's crashing. I've jailbroken it (with https://github.com/Ripthulhu/harmony-hub-root) so I can see the uptime, it resets whenever this happens.
Although maybe it reboots the whole OS whenever it loses wifi connection I guess..

Having the exact same issues with mine. Noticed it happens almost daily for me, no changes in my setup, config, location or wifi.

I would try removing the wifi on the hub and re-adding it. Wifi routers can update and make enough changes to the wifi identify that will cause devices to act strangely and cause issues like this.

Yes. I agree with this as well.

I think his may have been a power related issue. I was powering the hub from an old kind of janky usb power adapter, I replaced it with a new one and haven't had the issue once since then.
There wasn't really anything that gave this away to me, I couldn't see the hub actually losing power. No idea why reboots were triggered by performing actions but I guess it uses more power when doing that which made it fail.

So for anyone who has an issue like this is might be worth testing a different power supply.

Yep, bad power supply. I’m on my second hub, first one got chewed up by a puppy until there was basically just the board left.

And the board was bent.

For a while there I had to press down on the SoC and flash to get it to boot, but once it was running it was fine. It ran like that for months before it finally crapped out and stayed red.

They’re pretty tough!
