Well, since no one said STANDARD Zigbee, I’ll throw in Xiaomi. Try to pair a Non-standard Xiaomi Zigbee device to Hubitat or SmartThings and you’re inevitably going to get inconsistent results. Pair a Xiaomi Mijia or Aqara device to a Xiaomi Mijia or Aqara Gateway (their lines seem to work equally well with both Gateways) and you get really inexpensive devices that pair very easily to an inexpensive hub and just don’t falter, as has been my experience, as well as many others.
There’s currently only two ways I’m aware of to link the Xiaomi Gateway to HE. The Aqara HomeKit Gateway via Homebridge and HomeKit automations, or a very specific Xiaomi Mijia Gateway and an app called MiConnector. This is a more complete integration than via Homebridge, but more complex to achieve.
If you think you might swap your main hub down the road, then the Aqara HomeKit Gateway is the safer bet due to the huge number of Homebridge plug-ins available to integrate various hubs with HomeKit if the hub doesn’t natively support it.
