No numbers on the remote is a big issue. Unless I can use an after-market alternative remote with numbers etc, and preferably a QWERTY keyboard on the back, it would likely be a deal breaker for me. I have a MINIX Neo A3 airmouse, which is a media remote on one side and a full keyboard on the back. It would be great if I could use that.
Also, I have had issues with my current Sky box not liking learning remotes and IR blasters. That would also be major issue for me, as I'm planning to use something like a Broadlink RM Pro in a couple of rooms to ite control of all my devices (DVD/BD recorders, TVs, Soundsystems, heating, Sky etc) together and control them off Google Assistant. So I would be looking for that to work fine.
Minimum three satellite tuners (preferably four) or I'm not interested.
It would also be nice if I could continue to use the Sky app on my phone to remotely schedule recordings, like the current box allows me to do.
