The Koogeek O1US in my living room has been unreachable for about a month. Apple Home lists it as No Response. When I scan the network for HomeKit accessories every other device here answers straight away and this one doesn’t show up at all, so it isn’t the Home app being confused. The strip has power. It just isn’t on the network in any way that counts.

It’s a three-outlet HomeKit power strip, and Apple Home sees it as one accessory offering three separately switched sockets, named outlet1, outlet2 and outlet3. Firmware 2.3.16. Three independently switched sockets from a single plug is a useful thing to own, which is why I bought it in the first place.

The failure

It drops off and stays off. The only way I’ve found to bring it back is a factory reset and pairing it into Apple Home from scratch, which wipes its place in every scene and automation it belonged to. I’ve done that more than once. Doing it again costs more time than the strip saves, so at the moment it sits powered and dead in the living room.

The behaviour isn’t specific to my setup. Other owners describe the same sequence: the plug rejoins Wi-Fi without trouble, then fails to re-establish its HomeKit pairing, so it reports as unavailable while sitting on the network perfectly happily. Some have reported the Koogeek app hanging partway through a firmware update and never finishing. The fault has been pinned on Koogeek’s firmware rather than on HomeKit or any particular router.

No fix is coming

I went looking for a firmware release that addresses it. Checked in August 2026:

• koogeek.com returns no address records and no nameservers. The domain doesn’t resolve at all, so the support pages and firmware downloads are unreachable.
• The Koogeek Home app returns a 404 on the App Store. It was pulled from Google Play in November 2023.
• The products stopped being sold some time before that.

I ran the same App Store check against the iDevices Connected app, from a brand absorbed in 2017 that stopped shipping updates in 2023. That listing still loads. Koogeek’s doesn’t.

I’m not going to state the company’s legal status because I haven’t seen a filing. A dead domain, a delisted app and a discontinued product line are what I can actually verify.

Compare it to something older

Two iDevices switches in this house have run daily since 2016, on firmware that stopped being updated around 2019, from a brand that was acquired and wound down. They work every day.

Being discontinued didn’t kill those, and it isn’t what killed the Koogeek either. HomeKit pairing is local, so an accessory can outlive its manufacturer indefinitely provided the firmware holds its pairing. The iDevices units do. The Koogeek doesn’t, and it didn’t while the company still existed. Abandonment only removed the chance of it being fixed. There’s more on how that plays out over a decade in the iDevices Switch review.

Hands-on notes

Living Room, firmware 2.3.16, three outlets. Currently No Response in Apple Home and absent from a network scan that finds everything else here.

The pattern across ownership has been consistent. It works for a stretch, drops, and only a factory reset and re-pair brings it back. I’ve stopped bothering.

Nothing about the house explains it. Meross plugs, VOCOlinc plugs, iDevices switches, IKEA Thread sensors and Matter bulbs all sit on the same network and stay reachable. One accessory fails repeatedly and it’s this one.

Verdict

Don’t buy it. It’s discontinued, the offline fault sits in firmware nobody will patch, and the recovery procedure costs you your automations.

If you own one and it’s behaving, fine, but don’t put anything load-bearing on it. If it’s dropping the way mine does, replacing it is less work than resetting it again.
