Hallo zusammen 😉 Unsere Community wächst enorm, das sieht man an der Anzahl der Aufrufen aber auch an den inzwischen 700 Mitgliedern in unserer Facebook Gruppe – vielen Dank!! Vor nun 3 Jahren haben wir das Projekt Bienenwaage als Studienprojekt begonnen und sind immer noch fleißig am optimieren und verbessern. Inzwischen sind auch aus der Community einige… Read More »

Firmware v1.1

Die Firmwareversion kannst du unter Downloads herunterladen und anschließend auf deine Speicherkarte übertragen. Vielen Dank an Christian Weber, der an dieser Firmware sehr viel mitgeholfen hat. Neue Features und Verbesserungen seit dieser Version: Unterstützung drei neuer Sensoren: SHT31 + AHT10 + HDC1008 Unterstützung eines CO2 Sensors: EE895 (Übersicht aller unterstützten Sensoren hier: Schaltplan und Sensoren) Verbessertes Protokoll. Es… Read More »

Neue Platine (v2) für Raspberry Zero

Es gibt eine großartige Neuigkeit! Michael Drewitz hat die vergangenen Monate damit verbracht eine neue HoneyPi Platine zu entwerfen. Sie ist aus eurem Feedback entstanden. Generell ist es für den HoneyPi Versuchsaufbau nicht notwendig aufwendige Lötarbeiten zu verrichten oder eine Platine zu verwenden. Dies wird in diesem Beitrag erläutert. Jedoch vereinfacht die Platine das Anschließen der Sensoren durch… Read More »

Add-on: Stockkarte von

Wer sein Bienenvolk im Blick haben möchte, der setzt auf eine Stockkarte. ist eine kostenfreie App, mit der die Bienenvölker verwaltet werden können. Außerdem können dort auch direkt Messdaten visualisiert werden. Aufgrund der hohen Kompatibilität von unserem HoneyPi Messsystem ist es auch möglich, die Messdaten zur App zu übertragen. Dies ist völlig losgelöst von unseren HoneyPi… Read More »

Spannungsanzeige (PCF8591)

Wird der Raspberry Pi über eine 12V Batterie mit Strom versorgt, so kann mit dem Modul PCF8591 die Spannung der Batterie gemessen werden. Das Modul kostet nur ca. 5 Euro. Dies hat den Vorteil, dass man weiß wie viel Spannung in der Batterie verbleibt. Außerdem kann man auch die Eingangsspannung des Solarpanels damit messen. Der PCF8591 verwendet, wie… Read More »

Firmware v1.0

You can download v1.0 firmware here and then load it onto your SD card New features and improvements Multiple Thingspeak channels can be set up so that multiple hives can be monitored with one Raspberry Pi  If the Raspberry Pi is connected to your LAN it will stay continuously connected even when maintenance mode is started.  There is… Read More »

4x Half Bridge load cells

This article shows the wiring of cheaper “half bridge load cells” (YZC-161E). Such half bridge weight sensors are available on Ebay partly even together with a HX711 for only 9€. On Amazon they cost about 13€ ? Quality At constant temperatures, these sensors work okay, but these cheap sensors show a so-called temperature drift. This means that the… Read More »

Building a scale frame

Many beekeepers see the greatest challenge in the construction of the beehive’s weighing frame. As our picture gallery shows, there are many racks suitable for reproduction. In addition, our Facebook group also allows an exchange/trade among each other. In this article I would like to introduce the possibility to build your own scale rack. Otherwise there is the… Read More »

HoneyPi iOS App

Currently still in BETA test. Therefore we are looking forward to your feedback. Besides our Android App we now also have an App for iOS devices. With the LIVE display the current temperature and the weight of the bee colony can be constantly checked from the smartphone. The “HoneyPi Dashboard” app runs as a web page in the… Read More »

Visualize and analyse measurement data

The HoneyPi measurement system uses the ThingSpeak platform to store the data. ThingSpeak is open source and specializes in storing all measurement data from the Internet of Things. The nice thing about it is that the whole thing is completely free of charge and can be done without special technical know-how. In addition, ThingSpeak offers many different interfaces.… Read More »

Time and energy management with Witty Pi (optional)

As of version “v0.1.1” of the firmware, the software for the “Witty Pi Mini” module is already pre-installed. You can connect this module to the Raspberry Pi – but you don’t have to. Since it is actually quite clever and can be saved especially in the winter months additional energy, we have supported this module obviously. You can… Read More »


HoneyPi gets even better! But we need your help. Give us feedback and contribute (maybe your own Raspberry Pi extensions). Our goal is to offer you a simple solution. Therefore there are continuous improvements: To-Dos for the upcoming firmware version ☑ An operating mode without Internet connection. This means that the measurement data can be downloaded on site… Read More »

LED (optional)

Is the HoneyPi and measuring mode or in maintenance mode? An LED light integrated in the housing can provide information about this. The light signals when switching between maintenance and measurement. The pre-installed green LED on the Raspberry Pi indicates the following: Function LED maintenance mode (“HoneyPi”-WiFi avaiable) ? lights up measuring mode ⚫ does not light up… Read More »

Calibrating load cells

Different load cells can be connected to the architecture selected by us. For this reason, it is possible to store a calibration for each connected scale in the maintenance mode. Since version v1.0 a guided calibration mode has been introduced. This simplifies calibration so that the text below is no longer necessary. The calibration consists of two values.… Read More »


Before downloading the firmware: Under Downloads you can download the latest version of the firmware. After downloading the firmware: Follow the steps in the instruction to write the firmware to a memory card. The downloaded ZIP file has about 720MB. After unpacking the image (IMG file) has about 2.3GB. After the firmware image has been written to the… Read More »

Shopping list

The parts list is intended for one beehive. However, further sensors can be connected flexibly. The connected sensors can then be configured in maintenance mode. Plug n’ Play and optional upgradeabilityNot all sensors need to be purchased and connected! These can be added at any time. The system also runs if, for example, only one temperature sensor is… Read More »

HoneyPi soon available for all beekeepers

After we finished HoneyPi as a university project in July, there will soon be documentation and downloads on, such as firmware and app. Some instructions have to be written. Stay up to date by following our Facebook page: HoneyPi in the news of the Duale Hochschule Baden-Württemberg (DHBW) Karlsruhe: Planned milestones: ✓ Upload of shopping list… Read More »

Why do we use ThingSpeak?

Beekeepers can register for a free account in ThingSpeak and create a channel for each colony. The decision to use ThingSpeak as a central web service to store the measurement data has proven to be correct. In addition to the obvious reason that beekeepers should not rent web space and that ThingSpeak is free, other advantages have emerged.… Read More »

Autonomous power supply at the apiary

Normally there is no power supply at the apiary, therefore this article is dedicated to the autonomous power supply of the Raspberry Pis (RPi). The Raspberry Pi 3 B needs 5.1V and 3A as optimal input voltage. Compared to other boards like the Arduino or the ESP8266 this is a lot. Nevertheless such a power supply can be… Read More »
