The Google OnHub, in pieces. Even after our review of Google’s OnHub router , the device is still a mystery. Today Google is selling a $200 Wi-Fi router with an abundance of processing power that promises to some day be a smart home device. We’re guessing it will power the “Google On” smart home ecosystem, but Google isn’t talking about any details today. Further Reading Perhaps the mad scientists over at iFixit can shed some light on the device. They recently ripped open the Google OnHub, displaying its internals for all the world to see. They found lots and lots of antennas, a huge heatsink, and it was mostly held together with clips. The big surprise is the sizable speaker that sits at the top of the device. During setup, the speaker emits a loud ringtone-like sound that pairs the OnHub with a phone, but the OnHub speaker is much larger than what you would find in a smartphone. It’s still a far cry from Amazon’s woofer/tweeter combo in the Echo, though. iFixit was able to confirm that the odd little “plug” in the speaker grill is really an ambient light sensor, which Google told us doesn’t work yet. There’s also a Silicon Labs EM3581 SOC network co-processor for ZigBee and Skyworks 66109 2.4 GHz ZigBee/Smart Energy front-end module, which are also dormant.
