Continuous Zigbee disconnection , Bad News

Hi All
Thanks for the Help
I have the following problem
i found 5 or 6 zigbee device disconnected i pair it, and all is working well
1 day later
the same devices 1 plus 1 minus get disconnected, i pair it again
5 hour later
they disconnet again , pair all ok for a day and then 5/6 devices disconnect again.
They are always the same all zigbee.
This problem start 1 week ago when after i added my last door sensor.
It happen once in past but now every day or more than once a day.

Some details
The objet that fall disconnected are
3 bulbs, 2 outlets, 1/2 door sensors... most of the times
sometine i can find 4 door sensor disconneted

What devices are having this issue?

I had a similar problem with my Xiaomi Mi contact sensors.

I found that my Sinopé thermostats would boot them off when they tried to mesh through them.

I moved them to a 2nd hub and continued having less, but still occasional issues until I added a lot of the Tuya Repeaters.

Likely the issue are your bulbs. Most zigbee bulbs are ZLL. These make terrible repeaters and will crash your mesh (the exception is Sengled as their bulbs don't repeat or zigbee 3.0 bulbs). Keep zll bulbs on a seperate hub.

i have only one hub

Some are like this

is mandatory to hame more hubs?

This is a cheaper solution

Other question
3 bulb disconnect too, they are connected directly to the hub i think
what i can do for them?

Those will need a repeater close by to work well.

Also, as @rlithgow1 noted, most Zigbee bulbs will cause issues and should not be on a hub that has other Zigbee devices.

Having more hubs can help when you absolutely want to have devices that don’t play well with others.

If you have a hue hub, pairing bulbs with it will work better and is what a lot of people do.

a devices under HUE hub can be handled like a normal device?
i have 2 ikea repeater near this sensors it should be ok?
HUE hub is the final solution or i have to buy a second Hubitat?

Yes, you can link your Hue Hub to Hubitat and then control the bulbs like any other device.

Ikea repeaters should help. It is what I use to have but I am finding that the Xiaomi contact sensors almost never disconnect since I changed them to the Tuya sensors. You want to ensure that the devices are not too far from the hub or the repeaters. Some setup have more interference, and sometimes the channel used will also make a difference (I am on channel 20).

Buying another hub is also a great option as it can also provide you with a backup if your hub has an issue, but you should try the other options first. :slight_smile:

Yes most of us connect shitty bulbs and other zll lights to a hue bridge or another Hubitat with only those type of zigbee devices so they're kept separate from the zha devices. So if you have a hue bridge, put them on there and use cocohue from Hubitat package manager to allow Hubitat to directly control them. My self, I prefer to use switches for my lights (Lutron Caseta), and bulbs for the occasional table lamp

Other few questions?
How i can see if the device is zll or zha?
I have for example Osram smart light bulb with temperature and intensity correction they are zll or zha?
Via Hue i have full control as i have with direct connection?

Do you mean this hub?

I believe the Osram are ZHA 1.2, or at least the older ones in the US were (newer ones might be Zigbee 3.0). In Europe, I believe they were sold as ZLL, and for a while they allowed you to "update"/change the firmware, but not anymore. If you're lucky enough to have ZLL firmware (or Zigbee 3.0), you should be able to pair them to a Hue Bridge. Hubitat doesn't care either way, and the problems aren't restricted to just ZLL bulbs (Osrams have a problematic reputation, and those, again, are usually ZHA in the US), but do seem to be more common with those.

The Hue Bridge you linked to above is the one (or anything that looks similar to that model; they've done at least one "silent" hardware update, but for new users I'd just avoid the round v1 model, which no longer works with Hue's optional cloud services, unless you see yourself never wanting those).

I just need to have a bridge for my "problematic" lamps. i don't need someting to program, more than the HE.

Someone have experience with Osram and HUE? and someone are from Europe?
