Still driving me nuts. I cannot get any Matter device connected to Homey. It always ends in 0x00ac. **unable to connect** internal (0x00ac). I’ve bought different devices, the most recent is the shelly 1 gen 4. The idea was that it does not required a hub to update the firmware. I started with the matter devices from Ikea, but I do not have an ikea hub, so maybe these ikea devices miss a required firmware update or something 🤷‍♂️ . Then I tried Switchbot smartplugs. I was able to connect the Switchbot devices to Homey, but I wasn’t really certain it was via Matter… Adding them was a weird process and it took a zillion years for them to get detected. The Shelly wanted to update the firmware on its own, since I connect it via Wifi to the internet. That worked. The Gen4 versions can connected via Wifi , Zigbee and Matter. I tried Matter, and the first time I tried, all worked like I would have expected. Fast responsive “next-next-next”… great, until the final step. After it says, devices added to Homey 🥳 I get the next screent that says: **unable to connect** internal (0x00ac) (sad trombone) 🫩 I tried to add it to Homekit (AppleTV or Homepod)… works as expected. 🥳 Enabled “Paring Mode” in Homekit and tried to add it to homey. Same result… **unable to connect** internal (0x00ac). 🫪 Where should investigate? --- _[View the full topic](https://community.homey.app/t/issue-with-matter-on-self-hosted-homey/147203)._
