That’s a con. You don’t need a “secondary hub” with any bulb that “needs” a hub since you can just use them directly with Hubitat. I’ve got Ikea bulbs that “need” an Ikea hub, Sengled bulbs that need their hub, Innr bulbs that need their hub, and Hue bulbs that need their hub.
I don’t own a single one of these hubs, they’re all connected directly to Hubitat, and aren’t bogging down my WiFi. I certainly appreciate keeping my 2.4GHz as un-congested as possible so my Sonos and other important WiFi devices that don’t have 5GHz work as well as possible. I suppose I could have a dedicated router for Sonos and another for WiFi bulbs… but that would be the silliest possible secondary “hub”…
The only exception to this are the maybe 1 or 2 bulbs on the market that use Thread, but those will with with a C8 via Matter if you have another device that works as a Thread border router, which a ton of people already have, as the newer Alexa, Google, and Apple stuff have a thread border router in them.
