With Google Inc. (NASDAQ: GOOG) paying what feels like an unheard of $3.2 billion to acquire Nest Labs, Wall Street speculators are looking further down the chain to see if they can get in on the next home automation companies. That being said, investors are chasing up stocks in Echelon Corp. (NASDAQ: ELON), Lantronix Inc. (NASDAQ: LTRX) and Control4 Corp. (NASDAQ: CTRL) in relation to the deal.

24/7 Wall St. is highlight each of these companies as a result of the moves seen in them. But be warned that secondary and tertiary strategies are nothing new. They can end very badly because some companies are so small that the investing community does not know of them.

Google bought Nest Labs because it was an easy deal to do. Nest has started selling its products and systems at Home Depot, and Google obviously plans to integrate things far beyond its thermostat and smoke/CO detection systems.

Does the value of these rise if Google bought the VC-backed Nest for a whopping $3.2 billion? In relative terms, yes. Will these be the next buyouts from Google peers? That remains to be seen.
