Do you need to have a cloud-linked OC200 for the update check to work correctly? Because apparently that check returns a "General Error" (I'm getting this info 2nd hand)

Don't think so. If I unbind my OC200, it stil checks for firmware (responding with »Your firmware is up-to-date.«). But IIRC »General Error« during communication with an Internet server could be caused by Omada Controller not being able to determine the MAC address for localhost (127.0.0.1). Just a guess, I never had this problem; it's from 2nd hand info, too. :-)

Update: re-binding my OC200 to the cloud didn't ask for password, so could be that cloud access is indeed needed for firmware update check. Can't factory-reset my device at the moment to find out, sorry. But why not bind it to the cloud?

Uhm, there seems to be more confusion on TP-Link's support sites/online firmware updates:

Online firmware update says no new version, according to the cloud page latest firmware is:

But actually there is a new one on the german support site with the same old version number with different release date.

Download from here, release notes are here:

Previous version (note the same version number) was:

So only build time or release number can be used to identify the newest firmware. After manual upgrade I get from the cloud page:

It seems that this latest firmware version is even not available yet through online update.

I think, official roll-out of Omada Controller 3.2.4 has just started.
