You dead nuts nailed it. I agree a customer is going to search for installer. That is no questions asked the most likely thing they would type in. I remember back in december reading the article you linked to ([Link: cepro.com]).
A home technology professional is probably the best name for it imho. Sounds a little more upscale then installer yet captures it well.

Technologist is just awful. There is about a -82.639 percent chance of someone searching for a home automation technologist.

Leave it up to a typical ceo type and our trade organization to put out a friggin survey polling the entire installer base as to what term fits best fits what we do, then choose the second least popular term and coin that as our industry moniker for installers from here on out. Home Technology Professional was the most popular choice. So why would u separate the installer and create a separate moniker for them as a technologist. He said he wanted to eliminate excess terms for our industry. How is a home tech professional not fitting for an installer. I love this... in closing he stated “Using the ‘licensed technologist’ term will make it so much easier to refer to our potential pool of labor”.
Cedia..... SMH

end of rant lol.
