Historically in this community those have usually been referred to as a “dashboard.” Or less frequently a “control panel.”
Two of the most popular are from third parties: ActionTiles and SharpTools. They have different features and pricing, so check out both. (SharpTools also has a rules engine.) Both are browser based, so they are typically run on an inexpensive android phone or tablet using WiFi. Both allow for customization. The aesthetics are obviously up to you. 
You can find lots of discussion of them in the forum. Here’s a useful thread:
(We should note that Terry Gauchat who posted in that thread as an ActionTools developer has sadly passed away since that thread was opened. He is much missed in the community. But ActionTiles was founded by a different person, @625alex , and remains a viable service even though you probably won’t get direct responses if you reply to one of Terry’s posts. If you do have ActionTiles questions, you can tag Alex in your posts here, or ask in the forum on the AT site.)
