4. Support real-time feedback of switch status when both the device and APP are online;
5. Support two modes of self-locking and timing (including countdown, cycle timing, random timing, jog switch),
6. There are 4 5V, 10A/250V AC 10A/30V DC relays onboard, which can be activated continuously for 100,000 times, with diode effusion protection, and short response time;
7. Power supply voltage: AC90-250V;
8. Number of channels: 4 channels, the maximum overcurrent per channel: 10A, the maximum total power of 4 channels: 3200W;
9. Onboard WIFI status indicator, relay switch indicator;
10. The PCB board and materials used in the smart switch adopt lead-free technology, with high-quality materials, environmental protection and safety.
11. Size: 93*87mm
Mode introduction:
Self-locking mode: each channel is independently controlled, press to open, press again to close;
Timing (jog switch) mode: each channel is independently controlled, press to open, and automatically close after a delay, and the jog time can be set from 2 seconds to 1 hour;
Timing (countdown) mode: each channel is independently controlled, and the countdown time can be set from 1 minute to 24 hours;
Timing (cyclic timing and random timing) mode: please check the app setting operation for details
Various modes can be selected by APP:
Mobile APP control:
(1) APP download and installation: search for ‘Tuya Smart’ APP in the Android/IOS application mall and install it
(2) Open the APP, register an EasyTuya account and log in:
(3) Device registration on the network: Press and hold any of the S1/S2/S3/S4 keys for more than 7S. When the WiFi status indicator (D5) flashes, it means that the device is waiting for pairing and adding, and the phone is connected to the WiFi router. (2.4GWiFi) and turn on Bluetooth, click the ‘+’ button in the APP interface, select the switch (Bluetooth), use APP to complete the addition, the indicator D5 changes from flashing to off, the specific steps are as follows:
Note: There are two other modes for network configuration. Bluetooth configuration is used here because registration will not fail.
(4) APP control device switch: After the addition is complete, the mobile phone can remotely control the device through WIFI/4G/3G network (if the WiFi is disconnected, you can turn on the Bluetooth and use the Bluetooth control within ten meters of the device). For example, use APP to turn on the first switch, then channel 1 is turned on, channel 1 indicator D6 is on, and the device connected to channel 1 works.
Instructions for 433M remote control:
(1) Directly press the A button on the remote control to control the on/off of the relay;
(2) The remote control has been paired with the 433M module in the device by default. If you need to pair other remote controls,
Methods as below:
?Code pairing method: press the button 2S on the 433M module in the device, release it after the indicator light turns on, and then press any button on the remote control. The indicator light flashes 4 times to indicate successful pairing;
?Clearing method: Press and hold the button on the 433M module in the device for more than 8S, the indicator light is off, indicating that all the remote controls have been successfully cleared.
