These are pretty simple upgrades, I agree not much that can go wrong with these, except the auto feeder, which I would be wary of. I have been debating automating some processes of my aquariums recently as well, such as adding an auto top-off system, but I am a bit cautious, since every brand seems to to occasionally malfunction, and overfill the tank. There are some safeguards you can install of course.
I may have to get myself one of those wifi surge protectors. Looks pretty neat. I could definitely use the day/night timer, as on one tank I have my main lights, and then a plant grow light, on reverse day/night cycles, to keep pH more steady through photosynthesis. I use a cheap reptile day/night timer, but they seem to break after a little while. Let me know how you like the wifi protector after you've used it for a bit, I'd be interested to see how long it holds up.
