Wink offers its Wink Relay Smart Home Wall Controller 2-Pack for $99 with free shipping. That's $44.50 per unit and the lowest per-unit price we've seen. (It's also $41 under the best price we could find for a 2-pack elsewhere today. For further comparison, we saw a single unit for $70 in January.) It features an intercom system and smart touchscreen buttons for light switches and other items. Tools for installation are also included.
