The plug functions fine, but if there�s background noise (TV, kids, kitchen sounds), it struggles to hear the wake word. I ended up repeating myself a few times. I like the offline design, but the sensitivity could be better.
Thank you for sharing your feedback. We apologize for the inconvenience. Background noises can make it hard for the microphone on the SmartVoice Wall Plug to pick up the wake word clearly. For the best results, we recommend using the plug in a quieter spot or further away from constant noise if possible. Thank you again for your support as we continue to improve the experience.
It�s functional, but the plug is a little bulkier than expected. It covers part of the second wall outlet on slimmer plates, which was inconvenient in my small hallway outlet. A slimmer design would be more helpful.
Thank you for sharing your feedback. We apologize for the inconvenience. We’ll share your suggestion for a slimmer design with our team for future improvements. Thank you again for your support as we continue to improve the experience.
I previously bought some wall plugs that work with Alexa and let me say they were a PAIN to set up. Not too complicatied but complicated enough where I got frustrated. This plug from Emerson was so easy and simple, and I don't have to worry about whether my internet is up or down, it just works.
Wow � this plug is a game-changer. I plugged in a desk lamp and a fan, and just by saying �Hey Emerson, turn on,� they powered up instantly. No app, no Wi-Fi, no hub � just voice control and it works every time. The USB-A and USB-C ports are a bonus for charging my phone and tablet. Super easy setup and excellent reliability.
I love how private this smart plug is. With offline voice recognition, I don�t have to worry about cloud-privacy issues or network outages. The plug is responsive within a couple seconds, and the dual-socket + USB output design makes it really versatile for both lamps and charging devices. Highly recommend for anyone wanting simple, private smart home control.
