The short answer

The Koogeek O1US is a HomeKit power strip with three outlets and three USB ports that keeps falling off the network. Getting it back means a factory reset and a fresh pairing. Mine last answered a month ago and hasn't been seen on the network since. No firmware update fixes this: the failure is in Koogeek's own firmware, and koogeek.com no longer resolves, so the support and firmware channels are gone.

What works

  • Three separately switched sockets and three USB ports from one wall plug

What doesn't

  • Drops off the network and only a factory reset brings it back
  • Re-pairing wipes its place in every scene and automation it belonged to
  • koogeek.com no longer resolves, so no firmware fix is coming

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 but is not on the network at all.

It’s a HomeKit power strip with three outlets and three USB ports; Apple Home sees the outlets 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 for now it stays plugged in but unused in the living room.

The behavior 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 still connected to Wi-Fi. 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 whose app last saw an update in 2023, and that listing still loads.

I’m not going to state the company’s legal status because I haven’t seen a filing; the checks above are what I can 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.

The Koogeek fails because its firmware loses the HomeKit pairing, and it was losing it while the company was still in business. HomeKit pairing is local, so whether it survives depends only on the accessory’s own firmware, not on the company’s servers. The iDevices firmware has held it here since updates ended around 2019. 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.

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

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.

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.

Common questions

Why does my Koogeek plug keep going offline in HomeKit?

The fault is in Koogeek's firmware. After a network interruption the strip gets back onto Wi-Fi, but the HomeKit session never comes back up, so the Home app shows No Response even though the device holds an IP address. Owners have found no remedy short of resetting the strip and adding it to the home again.

Is there a firmware update that fixes the Koogeek offline problem?

No. Even while Koogeek was active, owners saw update attempts stall partway in the app and never complete, and the failure traces to the company's own code, not to Apple's side or to any router. As of August 2026 a DNS lookup finds neither nameservers nor addresses for koogeek.com, so no download server remains.

Is Koogeek still in business?

I can't confirm its legal status, but every support channel has closed. Checked in August 2026: the koogeek.com domain has dropped out of DNS entirely, the iOS app's App Store page is gone, the Android app left Google Play in November 2023, and retailers stopped carrying the products before that.

What should I replace a Koogeek smart plug with?

Any current smart plug that pairs locally over HomeKit or Matter. In this house, Meross MSS110 plugs have stayed reachable for years on the very network the Koogeek keeps dropping from.
