I don't think about them because mine still work fine (with a bridge connected to Ethernet) with Alexa for several years without major problems. I have 90+ total of strips, light bulbs, and such. I'm at about the limit for what one bridge can support.

The HDMI audio Sync box is a PITA that doesn't work well and doesn't support many lights. It's a $300 paperweight.

There was a periodic bug where lights would turn back on after commanded to turn off, and wouldn't stay off. That happened maybe 1% of the time but hasn't happened lately.

I also have no-brand, BT-based I2C silicone ARGB "rope" that requires an I2C fan-out repeater because only about 12 feet / 4 m could be powered serially.

You might actually need two hubs, which is why the sync box doesn’t work very well. I don’t have the sync box but I noticed the hub struggling with automations on about 60 something lights.

I now have two hue hubs, and a zigbee 3.0 controller with over 120 devices.

Easily run 8m of the best (high density, super bright which is actually too bright) RGB CCT rope light from a single zigbee controller. Perhaps its the controller and power supply you are using?
