I have a Hue bulb that is paired to a Hue bridge. When I bought them it was a package deal of 2 bulbs, a motion sensor and a bridge. I used one bulb with the bridge for the last few months. I decided I would rather just pair the bulbs to the Hubitat and use the Hue motion sensor to trigger it.
I did pair the unused hue bulb and the motion to the hubitat but I have not figured out how to get the bulb away from the Hue bridge.
You need to reset the Hue bulb before it will pair to a new network. This is true for any Zigbee device, but it's particularly notable for Hue bulbs given how difficult they have historically been to get un-paired if you're currently using them somewhere. Most other devices have a "reset procedure" you can do with nothing but the device itself, like pressing a button or turning it on/off so many times in a row. The current generation of Hue bulbs (the ones with Bluetooth and Zigbee, not just Zigbee) added that, I think, but I can't find the exact procedure. However, all the other methods will work for any generation of bulb, including these.
These "other" methods can be easy: if you have the bulb paired to an existing Hue network (or can do so), just make sure the bulb is powered on--at the switch, not necessarily "on" and producing light--and remove it from your Hue setup via the Hue app. This should reset the bulb, making it available to pair to another network. If you ever want to move it back to Hue from Hubitat, politely removing it from Hubitat first should do the same (same with any network you put these on).
The "other" methods can also be more difficult. If the above doesn't work, a Hue Dimmer can reset these bulbs: keep the dimmer close to the bulb (within an inch or two), hold the top and bottom buttons together for about 10 seconds, or until the bulb blinks, indicating a reset. Various other Zigbee remotes can also do this with the right button holds (the famed Lutron Connected Bulb Remote, probably the Eria Dimmer, and maybe some Ikea remotes). Alternatively, you can use a third-party Hue app or the Hue API directly to put the Bridge into "TouchLink mode" to reset (or steal and then reset? I've never followed this process all the way through...) a bulb. I believe the Zigbee-wielding Amazon Echos can also be used to reset a Hue bulb by serial number, similar to the process you can use to add one to a Hue Bridge. Some of these methods may not work if the bulbs were used on a non-ZLL (Zigbee Light Link) channel, which won't be a problem with Hue but may if you use it with non-ZLL Zigbee hub like Hubitat. The best way to avoid this is to reset it before you remove it from a network, which "politely" removing it from its network usually does.
That's a good question, too! I like the functionality of the Hue Bridge, but more importantly, it should be noted that many Zigbee bulbs have been shown to be "bad" repeaters on Hubitat that can wreak havoc on your Zigbee network if you habe other kinds of devices, like smart plugs or motion sensors (or anything), paired to the same hub. The Bridge eliminates this concern since they are then on a separate network.
I just like having everything under one control, hubitat. I also did not like the interaction between the hue motion sensor and the bulb. For example under hue if the bulb goes out, as it was programmed to do after so much inactivity, when it comes on it is at 100%. I use it in a pot light over my desk and I much prefer 40%. so I was constantly turning it down. Did some research, no fix for that under hue. Under the hub, no problem, I have a rule ti turn it on to 40% on motion, and another to turn it down towards 0% after a delay of 20 minutes. I like to do it my way
It is the zigbee only type. I cannot see anywhere in the hue app to remove the bulb. I was able to remove the motion sensor but not the bulb. Before I would buy a dimmer I would take it out back and shoot it! I will hold onto it, might find a use someplace else with the hue hub.
Settings > Light Setup > (your light) > Delete, or at least that where it is on the current iOS app. May be a bit different on other platforms--and, of course,requires the bulb to still be paired to Hue, but the Bridge can usually "steal" one back with the serial number if you don't have any other way.
You still can! Keep the bulbs on Hue, but put the sensor on Hubitat (the Hue Motion sensors can pair to Hubitat). Control the Hue Bridge bulbs in the same way you'd control a directly paired bulb as part of whatever Hubitat automation you want. This will avoid the "Zigbee bulb repeater" problem that many Zigbee bulbs, including Hue, are known for when used on Zigbee Home Automation (ZHA) networks like Hubitat--so that's my recommendation. Some people still manage to have good luck. Others seem to but then run into hard-to-troubleshoot Zigbee network oddities later.
Sengled shouldn't be repeaters, nor should innovelli. That said the hue bulbs most certainly are. They use ZLL zigbee protocol where as most devices are ZHA. The problem comes when shutting them down and they're no longer repeating and your mesh goes tits hub. Many threads about this. It's best to keep them either on the hue bridge or another hubitat as the only zigbee devices in that particular network (then share through hub mesh). I picked up a hue hub at home depot with 2 bulbs on clearance for 35.00 a few weeks ago just to add some cree bulbs I had picked up on clearance a few years back for $2.00 at home depot when I had wink! (hahah). The hue bridge runs very nicely for me with cocohue.
Inovelli bulbs are repeaters, but they are Z-Wave, so not of concern for the issue at hand (though there are other concerns with them on a C-7).
That's one issue, but they also have issues when they are repeating: the "eat" some messages instead of actually repeating, causing the problems staff have observed (and likely some problems users have reported, though the exact cause of these is hard to troubleshoot without seeing the actual traffic).
Have several Hue and Sengled bulbs directly added to my Hubitat. Zero issues with them. Even those that are still on a dumb switch. Get found right away when power is applied. I realize this is not a good practice, but from a practical standpoint, they work just fine for me directly connected. It is worth mentioning that those are the only Zigbee bulb brands I use.
