The main goal for this is to have a hive sending data in areas not covered with network cable to house or outside WiFi range. There is also a problem with sites without AC power. This is also covered in the section for Solar Panel.

My setup for this is:

  • Raspberry Pi
  • HAT board
  • Weighing cells
  • 2 x DHT22 Temperatur / Humidity sensors
  • TSL2591 Lux sensor
  • Edimax E180 3G modem
  • WiFi from Raspberry

There are several things to think about

  1. Is this the only hive to be connected to internet.
  2. If there is more that one, you need to set it up as a router.
  3. If there is only two hives a ethernet cable between would be the most power effeciant.
  4. If there is more than two, you need a ethernet hub or using wifi between hives (wifi use a lot of power)

1. Only one hive connecting
Setting up for connecting to Internet

Check that you can see the USB modem: $ lsusb Bus 001 Device 004: ID 0c45:7401 Microdia Bus 001 Device 006: ID 12d1:1003 Huawei Technologies Co., Ltd.

Update to latest versions $ sudo apt-get update

Add program for connection to modem with disk partition $ sudo apt-get install usb-modeswitch

Install PPP driver $ sudo apt-get install ppp

Download and install Sakis3G application, this is stable, and easy to configure, more info on www.sakis3g.com $ sudo wget "http://www.sakis3g.com/downloads/sakis3g.tar.gz" -O sakis3g.tar.gz Unpack files $ sudo tar -xzvf sakis3g.tar.gz Make file executable $ sudo chmod +x sakis3g

Test connection (Use sudo, otherwise it maybe fails to open ports) $ sudo ./sakis3g --interactive 1. Connect with 3G 1. USB device 3. HUAWEI Mobile 1. (internet) - (APN, maybe it differ at your mobile provider) E180 connected to Phonero (24201). - Connected to internet

Check connection information

Make your own connection command

After testet internet connection, disconnect modem from menu
