I have used these with previous hubs without problem (2 different c7 hubs). I have reset them all (confirmed with blue/orange flashing light now when attempting to pair).
The C8 just will not pair to them.
I even tried doing this in the same room, a mere 10 feet from the hub, just to remove that as a possible issue.
Existing plugs of the same model that were paired with my C7 and moved to the C8 are working fine. It is only for trying to pair new ones that this is failing.
No - it most certainly is supported. Zigbee 3.0 is backwards compatible with ZHA 1.2. It is not compatible (for pairing) with the zigbee version used in Iris V1 devices.
Have you tried any of the alternate pairing methods that will be available if "regular" pairing fails? I have a couple of these on my C-8, so they can at least pair, though there must be something unqiue here why they won't, and maybe one of these will help.
Yes I have tried both to no avail. I have tried 2 of the plugs and both fail. I have 4 unpaired in total but stopped trying all after 2 failed pairing.
Lowes Iris had at least two generations if smart outlets branded with the Iris name.
The first one, a v1 Iris device, will not pair with the C8/C8-Pro due to the changes in the Zigbee radio chip and software stack on these newer hubs (i.e. Zigbee 3.0.)
Here is an example of an Iris v1 smart outlet that does pair with a C8/C8-Pro
The Iris v2 devices, were manufactured by Centralite. These devices all work fine with Hubitat hub from the C3 through the C8-Pro. I have a house full of Iris v2 outlets, leak sensors, motion sensors, and contact sensors. They are working great on my C8-Pro hub.
Here is an Iris v2 3210-L smart outlet
Iris v2 Motion Sensor
Iris v2 Contact Sensor
Iris v2 Leak Sensor
There were also some Iris v3 devices produced, just before Lowes decided to shut down the Iris platform. The Iris v3 devices should also work fine with all Hubitat hub models.
It is curious that your Centralite 4200-C Zigbee outlets are not pairing with Hubitat... I don't have any of those on hand to test with, unfortunately.
Don't own any of these, but do own many of the v2 3210-L's. Getting them to factory reset can be tricky and if I remember correctly, there were a couple of different ways to do it based on the firmware.
The hard part to reset on the old 3210-L outlets was their Z-Wave repeater. It required some rapid button pressing a specific number of times. I have long ago abandoned that portion of the 3210-L. Resetting the Zigbee portion is trivial, just hold the button while plugging the 3210-L into the wall.
Long shot, but try this. Start pairing on the hub, activate pairing on the plug next, wait about 25-30 seconds, and while the hub is still in pairing mode-restart the pairing process-on only the plug.
While doing all this, keep the plug as close as possible to the C8.
Maybe a long shot, but I ran into an issue with a GE branded Zigbee plug (I posted abut it here ) which, during initial join, only scans channels that are part of the "preferred channel mask" that is part of the HA 1.2 spec (Channels 11, 14, 15, 19, 20, 24, and 25).
My C-3 uses channel 18, and attempts to join this plug will always fail because the plug's radio doesn't include ch 18 in its channel scan when in join mode (though once joined using one of the preferred channels, it's capable of switching to ch 18 and operating perfectly if the hu'bs Zigbee operating channel is subsequently changed via Zigbee settings). I wound up temporarily setting my C3 to one of the preferred channels, joined the plug, and then switched the hub back to Ch. 18 (the plug followed the channel change back to 18 and has been operating without issues since).
I have a couple of these on my C8, and they have paired to it without issue.
Not saying your problems aren't real, I've have Zigbee issues on my C8 that were specific to my setup as well. Just wanted to note that they can work with the C8 line.
My C8 is on Zigbee channel 15, power level 8, FWIW.
When you change channels your existing devices will need to reconnect and that can take a little while sometimes. Just making sure you're aware of that. In some cases I've had some repeaters I've had to unplug and plug in again to get them to reconnect.
Also depending on your local 2.4 gigahertz Wi-Fi environment and any other Zigbee controllers you have in your house, 15 may or may not be a great channel for you.
Technically yeah you can do that. I'm not sure it's a great idea though, to flip your Zigbee network back and forth between two channels quickly. Outside my pay grade, but might not be a great idea. @ogiewon@Tony@kkossev may know more about that.
