If you want zigbee, then this is the only choice. If you only want Zwave, then a Zooz 700 series dongle wirks fine. You don't need anything additional for Matter, since it's IP based. To support Matter over Thread, you need a border router.

The gear is on the far right at the top, right under "Logout"

Well you add the new Alexa spoken in the portal, you get to choose from several types: You need to click on "Scene" to define it as a scene to Alexa. That's probably what you did, since you won't see your scene names in the select list if you choose something else. Unless you have Devices and Scenes with confusingly similar names! But you say it used to work, so that sounds like an unlikely issue. It probably boils down to something creating noise, as was said initially. Lighting devices can go bad, so you can't rule that out without testing. I don't know how many lights are involved in that one scene or how much trouble they are to temporarily remove (light bulbs only need to be unscrewed). The trick is to remove one at a time and test again.

Battery powered Insteon devices don't relink automatically. You have to put them in linking mode and restore them one by one.

My thinking too, and you would have seen orange blinking on a wall switch that can't communicate with the PLM it's expecting to respond.

Yes, the direct device to device links are great for independence, and response speed. As for backups, well you know...

@raydoc , did you get it shared from Google home and configured in UD Mobile?

Just to add to tested devices: I got a GE Cync smart plug. I was at the hardware store for something else and thought I'd take a quick look at the smart devices (mostly bulbs). Not all GE Cync products are Matter compatible, you need to look at the boxes carefully. Again, it wouldn't add directly in UD Mobile, but adding it to Google home first and then sharing it worked, though it took two attempts. I also noted that Ikea will be selling Matter compatible bulbs. These will be the KAJPLATS line. Announced last fall but not yet available, in Canada anyways. Up until now they only supported Matter through their Dirigera hub, exposing their Tradfri Zigbee bulbs as Matter devices, much like the Hue hub does. Looks like they're discontinuing their hub, and support will die out this summer. They will also be introducing other Matter devices (sensors, etc) with equally hard to pronounce names! If the pricing and compatibility are there, it could be interesting.

If you replaced your PLM and never did a PLM restore, then there won't be many shortcuts. If your old PLM is still defined in IoX then you might try a replace procedure. This restores the links in the new PLM's link table, and then updates every device with the PLM's new device id. However battery powered devices then need to be restored individually, by putting them in linking mode manually.

And I'm adding to my notes! 🙂

You'd have to open a ticket with UDI to ask if there is a script you could run to reset it.

Having discovered the possibility to rerun the Matter device Interview, I relaunched the interview on one of the Philips Hue bulb nodes (when you share to Matter from the Hue app, all devices get shared at once). I had initially shared them many months ago in Matter testing, and only had device On Off nodes. Lo and behold, the new interview updated all the Philips Hue devices, adding all the color and hue nodes for the lights with those capabilities. That's great, and reinterviewing sure beats deleting and adding back devices. Hue White bulbs give you On Off nodes (with dimming) Hue White Ambiance give you On Off, and Color Temperature nodes Hue White and Color give you On Off, Color Hue-Sat, and Color XY nodes This now leaves Hue bulbs with two ways to control them: from the Hue plugin, or directly as Matter devices. The Hue plugin offers three ways of setting the color (RGB, XY, or color name). while Matter only has XY. There is also a third way to control Hue bulbs, as Zigbee devices, but that doesn't give you all those options, and I believe cannot be done simultaneously as Zigbee and controlled by the Hue hub.

You can actually feel the resistance with button going in? If the Polisy is otherwise functional then it could be the button itself, though that would be unusual. I'd open it up and watch when you press the button to make sure that's what's you're pressing.

You held the reset button in until all LEDs blinked?

Being on a roll, I thought I'd also try the Nanoleaf bulb. This is a Thread device, and not known for being easy to work with. I already had it configured and working in Alexa, So I generated a pairing code in Alexa and tried adding it in UD Mobile. Nope, getting an error code. Ok...plan B was to share it from Alexa to Google home first, and then from Google home to UD Mobile. That worked 🙂 I think that Google home and UD Mobile are Facebook friends! The interview process took noticeably more time than the Cync bulb did, a good minute it seemed. And the end result was only an On Off device node, no color or hue nodes. Even though the Nanoleaf bulb is a color bulb. Btw you can redo Matter interviews by right clicking on the device node and selecting Matter -> Synchronize -> Update with Interview (tell us about yourself, how long have you been a light bulb?). I tried that but it remained just an On Off device. If I set the ramp rate to a slow value and turn it on, it comes up in a fast series of stepped intensities, looks like blinking. I suspect that it's the bulb firmware more than anything else since these are known to be difficult with compatibility. The same commands were smooth on the Cync bulb. I looked up the bulb in the Nanoleaf app to see if it would alert me to any firmware updates. Nope. But still, now the Nanoleaf bulb works everywhere: Alexa, Google home, UD Mobile, and in the Nanoleaf app. We're getting there!
