A sensor gateway to receive, check and aggregate observation data

Main characteristics:

• Import service for observation data (BayEOS Frames over HTTP)
• Completeness and value checks
• Interpolation and aggregation of observation data
• Live charts of measured values
• Export service to BayEOS Server

• Debian 11 (bullseye)
• Root login

• Login as root
• Install basic tools for installation
  apt-get update
apt-get install wget gnupg
• Import the repository key
  wget -O - http://www.bayceer.uni-bayreuth.de/repos/apt/conf/bayceer_repo.gpg.key |apt-key add -
• Add the BayCEER Debian repository
  echo "deb http://www.bayceer.uni-bayreuth.de/repos/apt/debian $(lsb_release -c -s) main" | tee /etc/apt/sources.list.d/bayceer.list
• Update your repository cache
  apt-get update
• Install the package
  apt-get install bayeos-gateway

• Open the URL http://localhost/gateway and log in as user 'root' with password 'bayeos'
• Open the administration menu and change the default root password

Let's send the cpu load of our pc to a local gateway:

• Install the python-bayeosgatewayclient module
• Install the python psutils module
• Run MyFirstBoard.py
• Open http://localhost/gateway to identify our new board record

• Set the board name
• Set the channel names and units
• Configure 10min average aggregation on each channel
• Turn the board auto export option on
• Access the board data on a BayEOS Server
