This integration causes my Hubitat to have CPU overload and Shutdown the Zigbee radio

[AlohaFlyer]

This integration is working for me, but within a short period of time, it causes severe loads on the HE CPU and shuts down the Zigbee radio.

Any thoughts on how I can make this more stable? My message queue is filling up and it can't handle it. I did turn off all logging.

What was the log showing? I have never heard of anything like that happening (although that certainly doesn't mean it isn't), and I'm not sure off the top of my head what might be the problem.

Thanks for your reply. Here is the error in the log.

System Message: Severe hub CPU load detected. Error Message: dev:612022-02-23 11:26:21.966 am errorjava.lang.IllegalStateException: Queue full on line 427 (method off)

My scenario:

• 48 ZIgbee - Sylvania RT5/6 RGBW lights, 2 Sylvania ZIgbee Outlets, and 1 Zwave Kiwkset Door Lock
• No other automations or Apps
• Drivers are Generic ZigBee RGBW Light, Generic Zigbee Outlet,

-- Home Assistant side sees all of the entities correctly. -- HE side works, then stops and says Severe CPU Load, then shortly after will shutdown the Zigbee radio -- Should I be running an Events Server, configured on the HA side?? -- Should I add a URL to POST device events to, on the HE side?? -- Do I need to configure this "Enable these hosts (comma separated) for CORS support", on the HE side?? -- I am basically using my HE as a Zwave/Zigbee Coordinator to feed HA. -- I wonder if it is an integration configuration error on my end.

Try turning on debug logging for the integration in HA. The only thing I can think of offhand is that HA is, for some reason, sending tons of device commands to HE. The integration itself shouldn't be doing that; it receives events from HE and passes them on to HA, and it sends commands to HE when asked to by other parts of HA, but it doesn't send device commands by itself.

Should I be running an Events Server, configured on the HA side??

The integration starts one up automatically

Should I add a URL to POST device events to, on the HE side??

The integration should set that automatically. If you look in the Maker API instance in HE, the POST URL should be set to an address that includes the IP address of your HA instance.

Do I need to configure this "Enable these hosts (comma separated) for CORS support", on the HE side??

You do not.

I am basically using my HE as a Zwave/Zigbee Coordinator to feed HA.

That's how I use HE, too 🙂

Thanks Jason. I did look at HA and I found an automation I had forgotten about that was meant to save energy by turning off of my exterior lights off. I had accidently left it in a mode that was updating about 80 lights every second! lol ! Anyways, I have that disabled and will watch it for a day or so and report back. It was obviously flooding the HE with requests. Thanks for your patience. And thanks for a nice integration. How can I donate to your fine work, and great support?

We can close this bug. My problem was that HA was running an automation that was overloading the HE system. I am up and running and stable now. Thank you for the help
