How to add Ikea DIRIGERA to Matter integration? | Home Assistant | Page 1

Hello everyone! I can usually figure things out, but I'm running into a real head-scratcher. I recently bought an Ikea Dirigera and some of the Inspelning outlets to try and do energy monitoring for a few devices. The issue I am running into is that when I go through the steps to add the Dirigera to the Matter integration, it fails with a generic "Unable to add device" error, and seemingly no log entries either.

The steps followed are, Connect hub to ethernet, connect phone to wireless network on that same network segment, open the Ikea smart app, open hub settings, "Create matter bridge", copy the code given, open Home Assistant application, add device, add matter device, no/new, more options (this doesn't have a scannable QR) , accessory isn't shown, "enter code", paste code. And it fails with a generic error.

Not to put the cart before the horse, but I see few reasons for this to not work. The fact that the Home Assistant app can't seem to locate the hub device automatically is a bit of a clue. I can pull up the licenses on the web port of 8082 on the Dirigera device. I set a DHCP reservation so that I would always be able to locate the device on the network, which is how I have the IP. Firewall exceptions are set "allow all" in both directions. I'm bringing this up because I am 99% sure that between these things the issue is that there is some unwritten assumed dependency on some network protocol or facility that isn't enabled on this network, but I have found nothing even hinting as to what that might be in any of the reading I have been doing. I would have posted this in Open Protocols etc, but I don't think this has anything to do with Matter itself, rather Ikea's implementation of this device.

If anyone can tell me what it is that I'm missing, it would be greatly appreciated.

udated to latest os? Rebooted?

Latest Home assistant? Yes. I have also reset and restarted the ikea Dirigera many times. I have not restarted Home Assistant, but I suppose I could do so. This is a HassOS VM by the way.

Installation method
Home Assistant OS
Core
2025.10.1
Supervisor
2025.10.0
Operating System
16.2
Frontend
20251001.0

no restart but a full reboot of vm will do

outer viper Oct 6, 2025, 6:54 AM

#

Done. Should I try again?

vapid summit Oct 6, 2025, 6:54 AM

#

yes please

#

after (firmware) updates i usually reboot vm as a restart sometimes is just not enough to kick things into the right place..

#

I still get "Unable to Add Accessory".

vapid summit Oct 6, 2025, 6:56 AM

#

reboot hub too?

#

i have to bring my car to the mechanic, i'll be back in a while, or others will kick in from here.

It takes a bit for it to come up. I also have to sleep for a short while but I will be back inline in 6 hours or less. FWIW I have restarted everything a whole lot trying to get this silly thing working.

I still get "Unable to Add Accessory".

To follow up: I asked my local smart home guys, and it turns out that the Matter protocol specifically hard requires IPv6, which I have disabled on the network segments I'll be using for this little exercise. Because of this, it's not ever going to work, and I will need to return this and go buy something else. Thank you for looking into it though!

yeah ipv6 makes sense 😉

@outer viper Chances are that IPv6 isn't actually the problem here, because
a) HA would also use IPv4 adresses to communicate with dirigera,
b) fe80:: addresses should be generated on the fly via SLAAC.
But the fact that you mention segments might be a problem:
a) Then IPv6 would not neccessarily be routed
b) Even if it was: Matter uses multicast DNS for device identification, which is not being transported between segments by default.

Your conclusion may very well be the same though.

gentle raven <@823545781268512781> Chances are that IPv6 isn't actually the problem here, bec...

IPv6 is blocked; Multicast DNS is also blocked, or at the very least won't cross the boundary that it needs to cross here. So, I think you're right. I'm going to need to go with some other solution, but the devices I want to use in the end, are just zigbee and I see there are options in that space. Thank you for the input!

#

if ha is on a diff vlan, then mdns would need to be reflected between vlans. If you are going to use zigbee only (wich i would recommend) then i would ditch matter

gentle raven Oct 6, 2025, 3:05 PM

#

I mean the decision is totally yours, so out of curiosity: Why wouldn't you want to host HA and Dirigera in the same network segment?

#

and @outer viper just because you mentioned ZigBee only: That "something else" could possibly be an HA compatible USB stick to create a ZigBee Network and migrate stuff to HA.

#

Home assistant is accessible to/from the outside while the dirigera should be isolated from the outside. HA is in the "DMZ" zone while the dirigera would be in the "IOT" zone. I can allow whatever needs to pass between those two points, but everything else is firewalled.

Also, no go on the USB stick as this is a VM that will roam around (live migration).
