TOMZN 2026 New Model WiFi Smart Automatic Transfer Switch TOQ7s-125A 

Smartlife/Tuya App Supported

Seamless Dual-Power Control with Tuya / Smart Life App Integration
Take absolute control over your home's power dynamics with the New Generation TOMZN WiFi Smart ATS. Engineered specifically for modern solar-hybrid systems, backup generators, and grid-tied setups, this smart Automatic Transfer Switch ensures your home or business never goes dark.
By pairing seamlessly with the Smart Life / Tuya app, this new model upgrades a standard mechanical changeover into an intelligent, data-driven power management hub.

🌟 Key Features & Innovations
📱 Full Smart Life & Tuya Ecosystem Integration
No more running to the main DB (distribution board) or distribution panel. Monitor your power sources, check current status, and manually switch between City Power (Grid) and Backup Power (Inverter/Generator) straight from your smartphone from anywhere in the world.  

⚡ Millisecond Uninterrupted Switching
With an ultra-fast transfer speed, your critical appliances—like computers, Wi-Fi routers, servers, and smart TVs—won't reboot or skip a beat during power transitions. It provides a seamless jump between sources.  

🤖 Smart Automation & Smart Scheduling
Create intelligent automation routines within the Smart Life App.  
 Example: Program the switch to automatically shift heavy loads to solar/battery power during expensive peak hours, and bounce back to the grid during cheap off-peak hours.
🛡️ Enhanced Safety & Manual Override
Equipped with a physical manual/automatic toggle switch and a safety padlocking handle. If Wi-Fi ever drops, the heavy-duty internal mechanical interlock guarantees total safety, preventing both power sources from engaging at the same time.

🛠️ Typical System Application
 Solar/Inverter Priority Setup: Keeps your home on cost-saving Solar/Battery power (Source B) as long as the battery holds a charge, automatically defaulting back to the Grid (Source A) the millisecond the battery runs low.
 Generator Backup Setup: Automatically detects grid failure and routes power seamlessly to your backup generator or UPS once it fires up.
