I migrated over a hundred devices from two Wink hubs last weekend. Not nearly as bad as I thought. I have one misfit I can’t figure out. My Lutron Serena shades show up as a color bulb in both Hubitat and Sharptools. So every time I push that tile I get a color selection wheel. Remarkably enough the on and off buttons to function to make the shades go up and down.
When you added them through the Lutron Integration, did you pick the Shade as the device type? When you say they show up as a bulb in Hubitat, where are you referring to? Dashboard? Device page? Sharptools would only pick it up as a color device if you added it in the "color bulb" section on the SharpTools app in HE or if you were using the wrong driver. As far as in HE, you have to pick which tile to use in the dashboard. You can use the Shade tile.
I went a took another look, it looks like the only way I was able to create a group of shades was under the dimmer option in groups. This is why they bring up the color wheel. From what I can tell there is no way to create a group of shades.
SharpTools determines the tile template based on the reported device capabilities. It sounds like the device group is reporting that it's a Color Control device (even though the individual devices themselves don't support color control).
You can change the template using the following steps:
