==What is it?==
[[Home]] appliance to control other [[Amazon]] [[Blink]] devices.
According to the manufacturer:
"The Sync Module is a hub that plugs into an electrical outlet to relay commands and network details to devices in the system it manages. The [https://support.blinkforhome.com/en_US/faq-sm/sync-module-2-faqs Sync Module 2 ] requires a power outlet and is connected to your always-on Wi-Fi network to handle activity for up to ten [[Blink ]] devices. This extends camera battery life, saves clips without a subscription, improves convenience for scheduling, and arms a group of devices at once."<ref>[ https://support.blinkforhome.com/en_US/faq-sm/sync-module-2-faqs]</ref>
