Jessica,
I will chime in on the ECU part of your inquiry. This is a bit of a loaded question. There are so many options now, it really depends on what they want to control/have access to.
Most people start off with a thermostat and a video doorbell, you can them move onto locks and light switches. I will warn you that although marketed as a "DIY", most consumers would find the setup daunting.
If you are totally green, I would start with Alexa and a thermostat or a light bulb (no install required). There are light bulbs that do not require a hub, so it can be a very inexpensive way to get started.
Now, if they are wanting to operate a number of things, TV, locks, and all that - that is a hoarse of a different color.
Sincerely,
