Hi,I had ~16 Serena honeycomb shades installed this week, which all look great - our installer set them all up with pico remotes and they all worked when they left. I then went through and added all the shades and picos to our Caseta hub so I could control them through Alexa. This worked great for all but one shade, which just refuses to pair with the hub (it's pico has been moved to the hub). I've reset it several times (validating the alternating red/green flash at the end of the reset procedure). When I go to add device in the app, the green light on the shade does flash after ~30sec or so. When I hold down the button to pair I do then get the fast blinking. But the app never shows anything. It's in the middle of a bunch of other shades that paired so I don't think it's a distance/signal issue.Any ideas on what I can do? Is there a stronger reset than the standard documented one?Thanks so much,Daniel
