I couldn’t pin down exact shutdown dates for all three of these, so treat “cloud died” as unverified here. Wink, Iris and the original 2014 SmartThings hub were each dropped by their makers at different times, and the stuff paired to them stopped working.
Almost everything paired to one of these hubs is a standard Zigbee or Z-Wave device underneath the branding, and those devices don’t care who’s talking to them. A cheap USB radio plugged into a computer running Home Assistant can take over from the old hub directly. You don’t need the old hub for any of this.
What to do
- Buy a USB Zigbee or Z-Wave radio. A Sonoff, ConBee or similar dongle runs around $20 to $50, depending on which protocol your devices use.
- Install Home Assistant if you don’t already run it.
- For Zigbee devices, add ZHA or Zigbee2MQTT. For Z-Wave, add the Z-Wave JS integration.
- Factory reset each bulb, plug, lock or sensor and re-pair it to the new controller, the same way you’d pair it fresh.
Names and automations from the old hub don’t carry over, so you’ll set those up again.
