Devolo - DLAN 1200+ Wifi Firmware update 6.0.1

Hi All,

Bit of an odd one here. I logged into my HA server today to see an update notification on the Devolo network. Being a bit impulsive I just clicked the install button without thinking about it, then started looking for details after.

The update was concerning, in that it seemed to be bricked after it finished (solid red light), but after resetting the device it has come alive and I was able to re-add it to the PLC network.
I can log into it and find that it has a snazzy new interface… well I say snazzy, it’s black, otherwise it seems the same:

Sadly, it doesnt appear to connect to the other devices and pull my settings through from the devices still on 5.8.5, or at least I havent been able to get it to do that yet, whereas previously “config sync” just… worked.
Home assistant is also having issues connecting to it now.

It’s just this one device that seems to have had the update pushed, and the other ones cant find the update using the built in tool, Home assistant, devolo cockpit, or even available manually on the website.

They are all the same model number (MT:2675), so really not sure how or why this happened. I will contact Devolo support and keep everyone updated, but figured I would drop a post on for anyone who sees this notification and has the sense to check before hitting “install”.

As the device is not bricked, I think I should be able to roll back.

(I did have a bunch of images but it seems I am only allowed one)

The plot thickens… I just plugged in my spare ac adapter and that has also updated to 6.0.1 though cockpit :confused:

I have managed to get everything added back into HA though.

Got the same proposal from HA

Devolo cockpit is showing an update on this device (but not on others)

the firmware is not available in the official devolo website, and not proposed to all my devices

i wonder how this is possible

A second device has started to upgrade

It seems the firmware update infrastructure is enabling update in a sequential way using the Serial Number

  • this is not illogical
  • this has nothing to do with Home Assistant
  • this is just badly documented, generating stress. I am sure some users have lost a lot of time finding a solution for an issue that does not exist

My interface is still blue by the way…

Hi Legantois,

I don’t think it is serial number order, I think that was just a co-incidence on your side, as I had a
1611… and
1406…
that upgraded to 6.0.1, but then a
1603… and
1605…
that are still on 5.8.5.

The Devolo service team did get back to me and provide me with a link to the update for the ones that havent upgraded yet.

Perhaps the interface thing is to do with “dark mode” which is selected in my browser?

Either way, you’re correct in that this has nothing to do with HA.
