Residents at 685 First Avenue in Midtown East will find their tech integration much easier with a one-app solution called Pyng that controls most functions of their unit. It handles everything from A/V to temperature, and it can integrate with Amazon’s Alexa. The app can also create custom scenes—such as Party, Sleep, or Wellness—that can be programmed to occur routinely or whenever they desire. One-bedroom residences start at $1.52 million, with two- to four-bedroom units ranging from $2.875 million to $8.18 million.
