Are those three devices Bulbs, or something else? Hubitat only supports Hue lights, not outlets. You may be able to overcome this limitation by adding each outlet/relay to its own Hue Group. Then, import those Hue Groups into Hubitat. It's worth a try.
Another option may be to use the CoCoHue community integration. It might support a wider variety of Hue attached devices. @bertabcd1234 would know for sure.
