First Alert, a subsidiary of Newell Brands, has quietly acquired Luma, a home WiFi system maker that had raised $22 million in VC funding from firms like Accel Partners and Amazon.

Bottom line: This comes shortly after Luma rival Eero announced layoffs, reflecting the difficulty of competing with NetGear and Google.

More notes:

• The deal officially closed last week, and the two companies unveiled a joint product offering this week at CES (without announcing the acquisition).
• No specifics yet on pricing, but this was not any sort of win for Luma shareholders.
• Luma CEO Michael Bruinisse and chairman Paul Judge will transition out over the next couple months, but the Atlanta-based product and engineering teams will remain in place, per a source familiar with the situation.
• Per an internal memo from Judge: "Now that Luma is part of a Fortune 500 company (Fortune #208 to be precise), we have much wider distribution, reach and scale."
