What am I doing wrong here? I have a digikey z-wave controller stick, paired with my hub and I'm trying to use it to add some Fibaro motion sensors with no security (they pair successfully via hubitat with S0, but are clogging up network traffic).
Here's how it looks. I'm pressing the "Add" button, and putting the sensors into inclusion mode (sitting them right next to the hub, or the digikey stick yields the same results)
The node shows up in the controller software as the correct style, but does not exist at all in hubitat. I've done this multiple times with 2 different sensors, I've cold rebooted both the hub and stick several times. I have on occasion seen a longer dialogue that looks more promising, and then shows a device in hubitat, but it is always an unrecognized device that I can't use. They pair easily with the native hubitat interface, but being a C-7, I can't opt out of the S0 security. And yes, I've been removing the sensors with the PC controller after every attempt. The remove seems to go very smoothly, and it has worked to take some ghosts out of my network.
I thought using the stick was supposed to be the better method of z-wave management, and I'm out of ideas- any suggestions for me?
And sometimes I get this, presumably when the sensor goes out of pairing mode. I've tried waking it back up with one button press, or restarting pairing mode, to no avail on either.
I've used 2 different Fibaro sensors. One was successfully working with hubitat until I removed it. The other caused all sorts of network problems when I had it paired. I was led to believe by reading around that the S0 security protocol was to blame, hence why I got the stick to pair them unsecurred. I don't have anything else unless I start removing more working devices.
S0 is definitely an issue, especially when multiple devices are linked at S0. Like you, I have used a USB Z-Wave stick to connect them without security.
If one of the devices worked and this one doesn’t, I suspect it may be an issue with the device. Have you tried resetting it?
To be clear, neither sensor has successfully paired using the stick. Both successfully paired (and very easily) with the hubitat device discovery. Pairing is fine, S0 security device pile up is not. That's why I wondered if I'm doing the pairing wrong with the stick. Is there some sort of security setting I need to play with in the PC controller app? I paired the stick itself with the hub with no security as directed in other discussions. Is there some other setting I'm missing in order to pair an S0 device with no security? I haven't even made it to the stage of being asked about pairing security when using the stick.
Hmm, so I just re-paired one directly through hubitat to confirm it's working. It was easy, but it added the device both as a function new node ID, AND resurrected the old device ID in my list from the previous pairing (although that instance is not working). Is my problem that there is some sort of underlying ghost registration still in the hubitat radio? This is after removing the sensor literally dozens of times, and having nothing on my network list reflecting that. Is so, I'm not sure how to more definitively remove it. I can try a device reset, but it's the hubitat control that's still remembering the old device ID.
After the device was paired, I clicked on it on the left and then clicked on the “Security Scheme” button. If I remember correctly, I then selected “None” from the security options.
After the pairing was successful, I was only able to see it in Hubitat following a reboot.
If you see the device ID in Hubitat, you should also see it in the PC software. It is typically easier to remove it from the software, but you may want to try removing them from Hubitat first.
Remember to reboot Hubitat (via the reboot option) between changes on the PC software to ensure you can see them in Hubitat.
Oh nevermind, there was no ghost device- just me forgetting what I had named everything. But yes, it still pairs easily with the hubitat radio, but not via the stick. Not sure what to do from here. I guess I could re-pair the stick (already done it twice). Isn't pairing with no security the same as pairing with S2 then transitioning to none? On another note, the PC controller documentation implies you can select a node and change it's security pairing... or is that just it's security between the stick and device, not the device and hubitat? Ug, this is messy...
If I remember correctly, you can only pair securely if the USB stick is paired securely, so to avoid issues, I would recommend it is paired S2.
Once paired S2, I would expect that the Fibaro will pair S0. With the stick, you cannot change the security level of devices that were paired directly with Hubitat (I tried), but you can change the security level of devices that were paired with the stick.
OK, so you're saying I pair the hub in S2, then pair the Sensor via the stick in S0, and then I can use that "security scheme" button to change it to unsecure? Presumably right now my stick lacks the security level to add something the hubitat maybe?
OK, thanks so much- that worked like a charm to get the device into hubitat via the stick! I'm still a little unclear how I downgrade it's security now at this point. I can select the node, pick "Security scheme" (which by default is blank), then select none. It lets me do that, but there is clearly no communication being sent out when I do, and no change in hubitat. Is there some sort of a "send new security level" or something like that I need to send out.
I do remember it not being very intuitive... I suspect it will work just as you did it. After rebooting your Hubitat Hub, check what security level it records. If it says “None”, you’re all set.
Yeah, reboot didn't change it. There's a "send node info" button on the controller that seems like it might be the key, but it just tells me that the send info is queued, but that there is no assigned wake-up interval (I assume as it's a battery device). Does that ring any bells? Do I need to assign a wake up interval to get them to talk to each other to send out new info?
@erktrek - thanks I'll give that a try on the other sensor.
Ok, I got it to work. Thanks so much to @Sebastien and @erktrek for all the help. Here's the process in the end for the next poor schmuck to fight with this (and to remind me later when I've forgotten).
1- Pair the Z-wave stick into hubitat with full security authorization
2- Hit the shield icon in upper right on the PC controller. Deselect "enable S0" but leave the rest enabled (otherwise the controller loses its security permission to add devices).
3- Pair your S0 only device, and it will be joined in "none" security mode.
