Hi Richard,
a lot of devices work without their own gatweay/bridge as homey has the antenna’s. But it all depends on if there is an app. Best would be to check the app store to see if there is an app for the brand you use, and then scroll to see if your devices are listed.
Some apps use the brand gateway/bridge, others don’t. Some have both options (for example Philips Hue can be used with and without the bridge, using a different app).
And when in doubt you can always ask here about a certain specific device (in this topic) or the app specific topic if you can find that one, I’m sure there is anyone out here happy to confirm it for you.
And a note: Some apps show:
This means the app still needs to be updated to the new software to be available on the latest homey. Tere is a topic listing all the not converted apps and if they will be updated. Some apps won’t be available on the latest Homey anymore, or not yet.
