Gilligan:
Where is everyone on this project?
I have different prototypes running:
- Weight Platform Prototype I with Film Coated Plywood
- Weight Platform Prototype II low cost module, weights only one side of the hive
- Shields for Seeeduino Stalker (3.3 V) or Arduino Pro (3.3 V without RTC) and Yun / Uno (5 V)
- a prototype with an ESP8266 on a breadboard
- and also a prototype version with an Arduion Pro Mini and GSM
With the Seeduino Stalker and Arduino Pro as node I can use radio (RFM69) for data transfer, gateway is an Arduino Yun. I used this lib for RFM69: GitHub - LowPowerLab/RFM69: RFM69 library for RFM69W, RFM69HW, RFM69CW, RFM69HCW (semtech SX1231, SX1231H)
The ESP uses Wifi and I can send the datasets via REST or via MQTT. Tested with the libs for Adafruit IO: GitHub - adafruit/Adafruit_MQTT_Library: Arduino library for MQTT support and GitHub - adafruit/Adafruit_IO_Arduino: Arduino library to access Adafruit IO from WiFi, cellular, and ethernet modules.
I have also a Seeduino Stalker version with a GPRSbee, this sends the data via GSM/GPRS to a PHP script. Data visualization is done by Dygraphs http://dygraphs.com/ There is alos a GPRSbee lib for MQTT so switching from HTTP to MQTT should be possible easily (not tested yet).
We have also a Berlin (Germany) based group that develops a much more elaborated backend for bee monitoring purpose under the project name hiveeyes
It is based on BERadio, Kotori and Grafana mainly.
