WIFI smart dual power switch by TUYA/SmartLife
General
TOQ7S is a WiFi-enabled smart Automatic Transfer Switch (ATS) compatible with the TUYA/SmartLife app. It is designed for three‑phase three‑wire systems (AC380V, 50/60Hz) and supports remote switching between City Power (Source A) and Generator/PV (Source B). Functions include remote power switching, countdown, timer, and relay status monitoring.
As an upgrade over the TOQ7e series, the key improvement is that the APP status does not change with the power switching. When you select Source A on the APP, the TOQ7S operates as a normal ATS: upon loss of Source A, it automatically transfers to Source B; when Source A is restored, it automatically returns to Source A. The APP remains consistent with your selection, ensuring predictable operation.

Noted:
1.The product works with Three-phase three-wire AC380V 50-60Hz.
2.The WIFI chip is powered by source A. When source A loses power, the product cannot switch via TUYA/SmartLife.
3.The status of the APP will not change along with the switching of the device status. When source A is selected, even after source A loses power and then reboots, it will still switch back to source A. (TOQ7e is unable to achieve this)
