BASpi – Raspberry Pi-based BAS controllers
The first design is a 6-universal input, 6-relay output, BACnet server, Sedona-programable board which mounts on top of the Raspberry Pi’s GPIO header as a HAT.
With the installation of the free BASpi firmware and the HAT/daughterboard, you can turn your Raspberry Pi into a powerful BACnet-networked, Sedona-programmable building automation controller with resident web pages for monitoring and configuration and free software tools.
No one had used the Raspberry Pi in building automation before and no such boards were available on the market. There is now customer demand for more controllers built on open technologies.
The company has expanded the BASpi family with the addition of fundamental features required in building automation such as 24VAC/VDC power input, DIN rail mounted enclosure, large screw terminals, and capacitor-backed Real Time Clock for maintaining schedules.
On the horizon are a few more models which open up even more possibilities to open control proponents.
These new BASpi models incorporate feature sets currently in demand such as cloud connectivity, weather API, REST API, MQTT over SSL, and Haystack.
The new additions to the BASpi series include a second open circuit HAT board for Raspberry Pi (6U4R2A) which is very similar to the first design with the difference that it now allows users to drive 0-10V output signals thanks to its 2 analog outputs in addition to its 4 relay outputs.
The BASpi evolution continues and the features pile up with the introduction of the BASpi Enclosed series.
These are the 24VAC/VDC, DIN rail-mounted controllers with larger screw terminals for convenient installation.
These two BASpi-IO 12-point controllers in DIN rail enclosures differ only by I/O type and are fully web page configurable with BACnet Server, weather API, REST API, email alerts, secure cloud connectivity using MQTT over SSL, and Haystack tagging for their 12 physical I/O points and 24 Virtual Points.
The BASpi-BCC (BACnet Client Controller) is different. This “controller” does not have any on-board IO, but thanks to its BACnet Client capability, 192 Virtual Points, and special NetV (Network Variable) Sedona components, it can read and write other BACnet device points on the network.
The BACnet client plus the NetV components allows you to treat any BACnet point on the network as a Sedona programmable point in the BASpi-BCC’s wire sheet.
