Review on 🌊 Smart WiFi Motorized Ball Valve Watering Timer - Automated Electric Water Shutoff Controller Robot with Tuya Smart & Smart Life App Control, Compatible with Alexa - No Hub Needed by Ali Mitchell

Based on ESP8266, with 2MB Flash. Gears and all gears are metallic as far as I can see. Has enough torque to drive most thrust valves. 90 degrees. Now for the issues: while the main arm is metal, it sits in a simple hole in the ABS body. I assume it will wear out sooner than it should. There are no reviews. A mechanical polarity setting relay cuts power to the motor at the ends with a single signal from the ESP and the limit switches. The board is installed on the limit switches, nothing else holds the board except for 4 switching contacts. If this thing falls apart, you won't be able to see it from afar. He will probably report that everything is fine. If the motor or valve gets stuck halfway, the power supply will never be cut off, most likely the motor will end up smoking. If the limit switch gets stuck in the closed position, this thing will mechanically self-destruct. controlled by diodes OR, permanently activated by hardware when the valve is open. You can only control it via connection "0" when the valve is closed. The iPhone app requires a registered account on an external server. I refuse. Knowing your limits is a good valve timing kit. Some of the cheapest options right now. I can't comment on the software as I immediately wrote my own Arduino based firmware to avoid being dependent on the cloud.
