If I was buying a “smarthome” here would be my questions:

If the “smart” thermostat stops working during the transition and the pipes freeze – is that covered by the seller?
Is the seller willing to be techsupport for at least 1 year?
If a “smart” feature fails what is the warranty offered by the seller?

As a buyer – I do not want to figure out a smart home. I want it to work. I would love the cat6 to be laid and data center closet with a patch panel. But I don’t want to inherit any devices with questionable patches, outdated security connected to wires that I have to reverse engineer.
