SONOFF Outlet Switches Editorial Review

The Sonoff S31 Plug is a popular smart plug that has many features and is compatible with various systems, including ESP Home and Home Assistant. Customers have found it easy to program and schedule, and the build quality is good. However, there are concerns over the company's demands for precise location data during the pairing process, which some users find suspicious. Also, the manual is tiny and unclear, which can lead to frustration during setup. Overall, the Sonoff S31 Plug is a highly recommended product that can be customized with open-sourced firmware.
