… and is running 20 degrees above usual.

I’m getting the following error over and over again, would anyone know what it means or at least point me in the right direction?

Thanks

Ok so morre than eecent enough hardware, i did a google on this [quote=“RoadkillUK, post:1, topic:979570”]
data is too short to contain 4 bytes
[/quote]
And my first hit suggests problems with the firmware on a zigbee stick. Can you check what firmware you are running and try to update it?

Thanks again, I’ve recently got some zigbee hardware so it’s all new to me. I’ll have a look.

Sorry it’s taking so long to answer, 1) I don’t know what I’m doing :slight_smile: and 2) HA takes 10 mins to restart!

I can’t seem to find an issue. I’m backing up my device, and I have a backup from this morning, before it went dodgy.

The firmware is up to date …

Take a look at this thread and see if you see any similarities Failed to deserialize ZDO packet / Data is too short to contain 1 bytes · Issue #1131 · zigpy/zigpy · GitHub

I have no idea what the issue is, It still runs. I’ll have another look tomorrow.

Edit: I’m at work today, but I’ve just checked my system and it’s running cooler since I restored yesterday mornings backup, but It’s still getting many errors (10255 times in just over 14 hours).
