FOCUS Transmitters: Connected beehive scales

Durability, Repairability, Simplicity!

With several hundred transmitters deployed at customer sites, this new design is beginning to prove its worth: perfect resistance to outdoor conditions and reliability are the order of the day.


The advantages of this design
- transmission and power supply are separate
- the transmitter features an LCD display

The separate power supply provides great modularity. It can be supplied either by our solar box, an external battery, mains power or a battery pack.

L’écran LCD apporte une plus grande simplicité d’utilisation. Il affiche :
– le voltage de l’alimentation (charge de la batterie)
– la qualité de la connexion réseau
– la valeur des 4 poids (si les pesons sont raccordés).
Si la tension d’alimentation est insuffisante (<6V), le bouton de RESET clignote et le transmetteur ne démarre pas.


- 1 to 4 weight sensors (load cells)

BS4R-SIG: The BEESCALE4 version SIGFOX "Plain for 4 hives

The "Original" version that uses the SIGFOX network to transmit data.
Allows to connect the 4 scales and the probes to a single transmitter "that does everything". Equipped with an antenna that can be offset and placed on the roof of the hive for better reception. Very economical, this version is limited to lowland areas, rather urbanized. It is often lacking in mountainous areas (Alps, Cevennes, Pyrenees) or in sparsely populated areas.

Are you covered by Sigfox?

We have extremely accurate coverage maps provided by Sigfox. These maps are unfortunately not public. There are small tools to estimate if the coverage is good. We could put them online as many connected object providers do but these tools are very imprecise and do not inform you with certainty. We prefer to give you a coverage analysis. Just ask us!

BS4G : The BEESCALE4 4G/2G "All terrain" version for 4 hives

BS4G Tout Terrain, the version for PRO beekeepers!

The "All Terrain" version which uses the GSM 4G/2G network to transmit data.
This version has been specially developed to allow beekeepers in mountainous and sparsely populated areas to use hive scales. It is a rather complex solution technically but is the only option for many beekeepers. This version is worldwide and works in more than 140 countries. It ensures a very good coverage in all the countries where we currently sell: France, Belgium, Germany, Switzerland, Denmark, Finland.

The SIM card is already integrated in the box. The antenna is also inside the box.

Why do we insist so much on 2G?

If it is relatively easy to propose 4G (especially with the new 4G-LTEM and 4G-NBIOT standards), it is much more complex to propose 2G (GPRS and EDGE standards). We have worked hard to be able to offer a module that communicates in 4G and switches to 2G if 4G is not found.
Why is this?
Today 4G is far from providing full coverage in Europe, most often in remote areas, it is 2G that provides good coverage for GSM. According to operators, this situation will continue until at least 2035.

Extension module for BS4R- SIG or BS4R-4GBS4R-EXTEND

MS4R_EXTEND : The extension module to increase the number of hives per transmitter from 4 to 16

This configuration is a unique concept. It has seduced many beekeepers and apiaries schools who wish to have total control of all their hives. Coupled with the MeteoMiel data manager, this makes it a powerful apiary management tool.

The maximum cable length between 2 units is 7.50 m, covering most apiary configurations.

What budget?

Our priority is the reliability and durability of our equipment. Nevertheless, we keep our costs competitive. For 16 equipped hives, the cost price is €100 (excl. VAT) per hive.

By accurately tracking your hives, you'll never lose a swarm or miss a feeding (and use less of it). Used correctly, it pays for itself in no time!
