A:Answer Yep, you can use ANY of the AmpliFi devices (standalone or Meshpoints) and add them into your existing Amplifi network. Their Support articles and Amplifi App have a pretty easy to follow tutorial about. I'd post the article directly here but Best Buy doesn't like URL's, so just search "Amplifi article 360016183893" and you should find it. Only downside: most Best Buys in my area don't sell the additional units on their own but they're certainly available through BestBuy.com, the vendor, or elsewhere. The two recommended products below would work just fine.
