I have Logitech Home Companion Hub and it works fine w.r.t voltage. But I always had problem with their harmony keyboard. It always lose connection with the hub.
Even iam using the logistics harmony elite home system. And can't recommend it enough. I have programmed it just once. And it works every single time. Now I have dumped all the original remotes for my blu ray player, roku uhd, cable box , LG tv and marantz sr6011.
