• Based on dustmeter.

The setup will present a BACNET device with a collection of AnalogInputObjects. The AnalogInputObjects are the readout of various remote meters.

• A thermorasp that runs the server.py
• A pumpstation that runs the daemon
• A DYLOS DC1700 air quality monitor connected to a USR-TCP232-302 on TCP server mode listening at 8888 port

• python 3.4 or newer
• bacpypes 0.16
• PyQt5

pip3 install bacpypes==0.16

apt-get install python3-pyqt5

python3.4 main.py

Please make sure previous seesion of main.py have exited and relased the network port.

The configuration file is called server.cfg. It contains multiple [sections] of key = value pairs. Lines can be comments by prepending a #.

The server section is the main configuration section. It has the following configuration keys:

• ip: IP address String
• port: Integer
• objectName: String
• vendorIdentifier: Integer
• vendorName: String
• location: String
• modelName: String
• description: String
• dustmeters: Optional, list of space seperated section names
• thermorasps: Optional, list of space seperated section names
• pumpstations: Optional, list of space seperated section names

The last three keys dustmeters, thermorasps and pumpstations have the value section names seperated by spaces. Each of those section name corresponds to a configuration section of a meter to monitor.

All meter configuration sections have the following optional keys:

• description: String
• deviceType: String
• updateInterval: Integer
• resolution: Float

A section that has been given in the value of the dustmeters key can have the following keys:

• host: String, defaults to localhost
• port: Integer, defaults to 8888
• name: String, defaults to dustMeter
• default_dust: Defaults to 0
• reconnect: Bool, defaults to True

A section that has been given in the value of the thermorasps key can have the following keys:

• host: String, defaults to localhost
• port: Integer, defaults to 50007
• name: String, defaults to ThermoRasp

A section that has been given in the value of the pumpstations key can have the following keys:

• host: String, defaults to localhost
• port: Integer, defaults to 63432
• name: String, defaults to Pumpstation
• reconnect: Bool, defaults to False

To add support for another type of meter, create a new module with a new class, which inherits from meter_base.MeterBase.
The module must be imported in the main.py file and must be added as a value together with the configuration key it shall use to the METERS map in main.py.
The module needs to have a function called getMeters, that takes a map of configuration values, which was read from the configuration file, and returns a list of new meter objects.
The new class must implement start and join methods, which have the functionality of those of threading.Thread.
In addition the class has a stop method, which gets called when monitoring is supposed to be stopped, and a getPresentValue method to retrieve the current value.
