First things first: where do you live? Both device selection and services available can vary quite a bit. This is an international forum, and we’ve had community members from Vietnam, Malta, Greece, Mexico, Argentina, many parts of the UK and Europe, all over the United States and Canada, and other locations as well.
Second things second: what kind of budget are you looking at? A high-end system, very reliable with lots of features, typically cost 10% of the price of the house plus an annual fee. My own budget runs a maximum of about $500 per room and under $5000 for the entire project, although I’m willing to replace every individual piece of equipment, including the hub, every three years. Some people want to spend only 2000 and Expect it to last for 10 years (which typically means not just doing your own wiring but building your own devices).
And another critical factor is what your own highest priorities are. When you are looking at low to mid range systems, people could have very different priorities among three big project factors:
B) versatility in both the devices you can and the rules you can create
C) project cost.
At the lower end, you generally have to trade off between these three – – if you want high reliability, you may not only have to pay more, you may have to give up some versatility in order to get that reliability.
So different things work for different people, but I think the first thing is to put some scope on the project: what country will it be built in, what kind of budget are you looking at, and then what your priority balance is between complexity and reliability.
