Web view settings is done at:
Database and web view will be automatically generated when you fill in the form and press the SEND button.
A web address for the display of data from your weather station will be automatically sent to the entered email address.

2. SIM card adjustment
Insert the SIM card into the phone and turn the phone on. When the phone connects to GSM network,
turn off the PIN security.
Turn the phone off, and then turn it on again.
The phone should not ask for PIN security number when you turn it on.
Try test calling a known number and check how the incoming and outgoing calls function.
Turn the phone off, take out the SIM card and adjust the size of the SIM card.
GSM weather station accepts MICRO SIM standard.

3. Device adjustment
Carefully loosen the A, B, C and D screws and open the device cover.
Watch out for the cable connecting the cover (photovoltaic).
Loosen SCREW 1 (Figure 2), move the metal bar and carefully take out the GSM block.
Insert the SIM card as shown in Figure 3.
SIM card contacts must face upwards, the cut corner turned opposite to the direction of SIM card insertion.
Carefully place the GSM block back so that all contact pins are plugged in.
Turn the metal bar to the center of GSM, as in Figure 2. Tighten SCREW 1.

4. Adjustment of APN access point for GPRS.
Turn on the weather station by inserting the red connector so that all 8 pins are plugged into the
red connector. See Figure 2.
Using another GSM phone, send an SMS to the number you installed in MMS4:#APN,username,password
Example if there is no username and password:,,
Wait for about 3 to 5 minutes and then check if the web display is receiving data.If no data is being received, update the APN again.

4. Proper functioning and data transfer

After plugging in the red GSM connector, LED must must flash according to the diagram in Figure 4.

  1. SIM card initialization and attempted login to GSM network (GSM LED lights up for 0.1 sec, turns off for 0.8 sec)
  2. device registered to GSM network (GSM LED lights up for 0.1 sec, turns off for 3 sec)
  3. GSM device in GPRS mode (GSM LED lights up for 0.1 sec, turns off for 0.1 sec)

After the initialization of GSM block, the device starts the first measuring cycle. STAT. LED lights up in 9 identical intervals (lights up for 0.1 sec, turned off for 5 sec), followed by the measured data processing (lights up for 0.5 sec), followed by data transfer to the web. The blues STAT. LED will light up briefly 3 times (lights up for 0.1 sec, turned off for 0.1 sec). After data has been successfully transferred, the cycle is repeated. See Figure 5.


5. Energy save mode (sleep mode), battery voltage <3.49V
If battery voltage drops below 3.49, or the device resets for any reason, and battery voltage is below 3.60V, the device will not initialize. Instead, it will automatically go into energy save mode. The device will automatically leave this state when battery voltage increases above 3.60V and the battery keeps that or higher value for 10 minutes. See figure 6.


5. Battery voltage characteristic
The figure shows voltage characteristic with marginal GSM signal and maximum consumption. The value of voltage is visible at the bottom of the web display or in the measured values table.


6. Faulty operation
GSM LED is off, STAT LED is off or lighting up intervals are longer than 1 min:
- Check the red connector (turn it off and on).
- Check the battery voltage. If the voltage is below 3.49V, the battery needs charging.
- To charge the battery, unplug the photovoltaic cable and in its place plug in a 12.5-13.0V 2.5A adapter. The red LED on the charging block will be on until the battery is fully charged. The charging cycle will turn off automatically when the battery reaches 4.2V value. The charging cycle takes several hours and can be interrupted at any moment.

GSM lights up in 0.1 sec intervals, turns off for 0.8 sec:
- Check SIM card.
- Check if the GSM block is correctly plugged in and connected with the contacts.
STAT LED lights up as in below examples:
