Why choose 3G dual

Networks: Mobile providers continuously upgrade their networks and will stop supporting 2G in the near future. Some countries have already stop supporting it. 3G version ensures continuity and international support. Additionally, Huawei’s gsm module together with an external antenna “ensures” signal reception even in areas where mobile phones are out of coverage!
Second scale: With more samples the result is ensured. Also one can experiment with different breed to see which one performs better in the area.
Input/Outputs: It supports a variety of analogue and digital ports to connect many sensors like your watering system, siren, alarm switches e.t.c.


Antenna booster

High gain 3G antenna for areas with weak signal.

zygi assembly

All electronics from a zygi pro or 3G without the metal and wood construction.

Liquid level sensor

To be informed of bees watering. Can be mounted externally.

Reed switch

N/O or N/C magnetic reed switch for alarm.

Why choose Zygi

Very low power consumption

Consumes very low power in deep sleep mode being totally harmless to bees.

Cost efective

We made a clever design to make it affordable to hobbyist and professional beekeepers. We give 5 years complete warranty, lifetime support and trial free period.

Fully customized reports

The software supports sms/email/web interface. Up to three recipients for sms users and with any time interval at any mode of operation. Everything is easily programmable local or remote. Graph representation for each mode of operation. Android and iphone application are supplied free of charge.

Precision weight scaler

The mechanical contruction of the metal chassis with the 15mm plywood and the top quality weight sensor gives uniform weighing capabilities at every point of the platform. Scales are temperature compensated from -10° up to 60° Celcius giving outstanding linear measurements in a wide temperature range. The result is true 1 gramm analysis.


Proper system operation from -30°C to +70°C. Tests have been made at the laboratories of a certification company Labour SA.
GSM sensitivity has be proven better than normal mobile phones.

Technical support

We provide excellent support. We work on that project for several years and we are confident to provide 5 years of full warranty!

The adjustable sensitivity tilt sensor and external digital inputs activates the alarm system. Upon alert, corresponding messages are sent with the current coordinates of the device.


In web mode Zygi gives you the possibility to upload sensor data on the Internet. The alarm events are still sent by SMS for prompt intervention.

The web service is free of charge and accessible from any web browsing capable device (computer, smartphone etc.)

IoT sensor data logger in graphs

Zygi main system is placed inside a specially designed wooden box made of 1.5 cm plywood sheets giving extra strength to the weighting system, weather protection and invisibility to thieves.

What beekeepers say

Alichos Vasilis

It is a reliable scale with a very good accuracy. Configuration is very easy and the 3 batteries are enough for at least 6 months. It has become an absolutely necessary tool in my beekeeping occupation.
