Long ago I was using my Philips Hue Hub, but had some delay and disconnect issues and eventually migrated everything to ZHA and put the hub in the closet. Things have been working well, but I was curious now that Hue supports Push Updates (as of 2021.6), if there are any compelling reasons to move back to the Hub.
I know I’m missing firmware updates, and there are some cool 3rd party apps that can animate or sync the lights to music when using the Hub. But are there any other reasons to move back to the Hub… or not to move back?
Unless there is some specific feature of the hub you need (eg entertainment}, there is no reason to switch back.
Push only matters for sensors and remotes, and zigbee is intrinsically push.
