Python Haystack Utility
Pyhaystack is a module that allow python programs to connect to a haystack server using semantic data model for buildings (project-haystack).
Browse a campus, building, floor… find VAV boxes, AHU units, etc. Then extract history data from them and get the results ready for analysis using pandas or your own database implementation.
Actually, connection can be established with :
Connection to Niagara AX or Niagara 4 requires the nHaystack module by J2 Innovations to be installed and properly configured on your Jace. Refer to documentation of nHaystack for details.
pip install pyhaystack
Or you can also git clone the develop branch and use
python setup.py install
As stated in the web site
“Project Haystack is an open source initiative to streamline working with data from the Internet of Things. We standardize semantic data models and web services with the goal of making it easier to unlock value from the vast quantity of data being generated by the smart devices that permeate our homes, buildings, factories, and cities. Applications include automation, control, energy, HVAC, lighting, and other environmental systems.”
Pyhaystack is robust and will be ready for asynchronous development.
We have chosen a state machine approach with observer pattern. See the docs for more informations.
This implementation has been mostly supported by VRT and Servisys. We are hoping that more people will join us in our effort to build a well working open-source software that will open the door of building data analysis to Python users.
