Can use my existing Companion HUB to add another Harmony Ultimate One remote?
Do you mean put the better remote on an existing hub with the cheap remote? If that is what you mean then yes but you can have two of the touch screen remotes on one hub. No idea why.
I like to upgrade the cheap remote came with the HUB with touch screen, The existing remote can’t see the buttons when is dark in the room. I know i can install the app on the phone to control the devices, but i like to disconnect myself from everything by not using my phone.
Yeah, you can do that. I did it with mine. Bought the cheap remote with hub then got the better remote refurbished on Amazon.
thank you,i am going check Amazon.
