Depends on your long term goals. If you will keep adding devices you need to make sure that the chosen brands are compatible and you won't use at some point 8 apps to control your home. As a personal opinion, I've installed all of them and the most ROI(return of investment) you will get with thermostatic valves. +1 to Wiser as they are backed by Schneider Electric, so you have a piece of mind that they won't pull the plug suddenly and leave you without support for your devices.
