*Before using percentages, first calibrate the shutter switch (percentages cannot be used before calibration).
The panel is automatically calibrated. (use without internet)
Press and hold the “tentative key” and “up key” at the same time for 5 seconds, the switch will enter the automatic calibration mode, during which the keys will be locked (except for exiting the calibration) until the calibration is completed.

4.2. Manual percentage calibration

Usage scenarios of manual calibration: This function is a backup function. When the automatic calibration cannot be completed normally, the manual calibration mode will be used for calibration.
Operation method: Use both hands to press the upper, middle and lower buttons at the same time for 5 seconds, the switch enters the manual calibration mode, and the manual calibration can be completed according to the light guide.
The operation sequence is: up–pause–down–pause.
Note: When the curtain reaches the limit point, please click pause in time! To ensure that the percentage is accurate.

4.3. Exit calibration mode

During calibration, you can press and hold the “tentative button” for 3 seconds to exit the calibration mode.

4.4. Clear calibration data

press and hold the “pause button” and “down button” at the same time for 5 seconds, when the panel percentage indicator flashes 3 times, the percentage calibration data is cleared.

5. Set up and Use for TASMOTA 

Step 1 – On your smartphone, connect a hotspot like “tasmota_xxx”, created by the device.

Step 2 – After Step 1, it will go to the tasmota wifi connection page HTTP://192.168.4.1, and you should select the 2.4G ssid and input the correct password for pairing.

Step 3 – Once it links the wifi router successfully, it will show the IP address of this device and go to this page directly.[in some cases, the device IP address cannot display correctly but you cannot find the hotspot like “tasmota-xxx” anymore to pair it again. You can go to the router setting page, like 192.168.0.1, and find the device’s correct IP address.]

Step 4 – You can access the device via its IP address. When you see the page like below, the device is connected successfully.

B. Über Zeiteinstellungen:
Auch die Uhrzeit sollte vorher festgelegt werden! Dies ist besonders wichtig für Zeitschaltfunktionen. Stellen Sie die in Deutschland verwendete Zeit (Berlin/Deutschland) mit dem folgenden Befehl ein:
$TimeSTD 0, 0, 10, 1, 3, 60
$ TimeDST 0, 0, 3, 1, 2, 120
$ timezone
$99 time
