The Hiveeyes project conceives a data collection platform for bee hive monitoring voluntarily operated by the beekeeper community.
Let’s have a look at the environment:
Arduino is a popular embedded computing platform used intensively here.
Telemetry data is forwarded and distributed over a wide area multi-tenancy communication bus based on MQTT.
The Hiveeyes project for collaborative beehive monitoring uses two different kinds of sensor nodes.
Hiveeyes One sensor nodes transmit data to a gateway using RF, the gateway receives and decodes telemetry data from Bencode format, then forwards it to the MQTT broker in JSON. This is specified in BERadio specification and implemented in Python using the serial-to-mqtt forwarder beradio-python.
BERadio handles the radio link communication based on RFM69 and RFM95. It receives data messages in Bencode format over radio, decodes them and forwards them to a serial interface to MQTT encoded with JSON.
MQTT- and HTTP-based data acquisition, storage and visualization¶
Store measurements to the timeseries database.
Automatically create default Grafana panels for instant telemetry data visualization.
Detect events and anomalies on the telemetry data and emit appropriate signals.
There are different ways to get data out of Kotori, see Data export.
Using the Firmware builder, beekeepers can upload customized firmwares to their sensor and telemetry nodes derived from a “golden master” Generic firmware. Firmware images can be easily downloaded using HTTP.
Data currently is measured at intervals of about 15 minutes.
In the following graphs the weight of the hive is shown with the light blue line. The temperature sensor inside the hive is shown in dark blue and the sensor at the air hole, which is in the sun most times, is yellow.
Let’s have a look at the data. During the cold period at the end of April the beehive loses absolute weight because the bees have to live on their reserves. In contrast, the following two weeks were amazingly warm in May, so the worker bees are getting extremely busy.
From April 29 until May 13, the weight has increased by almost 14 Kg. On some days the beehive gained 2 Kg weigth due to pollen and nectar collecting.
It was the time of the fruit blossoms, so the cherry, pear and apple trees were in bloom in the nearby allotments.
The beehive gained a lot of weight on the 2nd of May. After six o’clock in the morning the temperature begins to rise, at 7:15 the first sun rays shine on the entrance hole. The first scouts leave the beehive at 7:45 and at 8:15 everyone is in the air. The beehive suddenly loses 120g since about 1200 bees are leaving to harvest.
At 9:20, the ratio between the arriving and departing bees reverses and the weight increases rapidly.
Throughout the day, bees are flying in and out, collecting nectar and pollen, explore and report. Even as the beehive is in the shadow from 16:00 and the temperature starts sinking, the bee colony continues to collect until 20:00.
1800g have been carried home. It was a good warm and important day, after the long period of winter and the cold snap at the end of April.
Schwarmalarm May 2016¶
This is a weight-loss event from The “Beutenkarl” scale recorded on 2016-05-20 between 10:11 and 10:26 hours CEST after a bee colony started swarming at the Hiveeyes Labs Beehive in Berlin Wedding, see also 2016-05-20 Schwarmalarm.
Entrypoints to the platform running on
swarm.hiveeyes.org as of 2016-01-29:
This section is about running the whole platform on your own hardware. Please be aware this is a work in progress. We are happy to receive valuable feedback for improving things gradually.
Install the platform¶
The most convenient way is by using Debian packages for all infrastructure services and Kotori, see Setup on Debian and Ubuntu. After that, the service should have been automatically started by systemd so the system is ready to serve requests.
Want to dig even deeper? Read on my dear.
When developing on Kotori or for ad-hoc installations, you should follow the instructions for installing Kotori as Python package.
In ad-hoc installations, or when turning off the systemd service, you might want to start Kotori interactively in the foreground:
/opt/kotori/bin/kotori --config /etc/kotori/kotori.ini --debug
For getting your development sandbox up and running, please have a look at Setup development sandbox.
