bospy 0.0.18

a package for accessing bos resources.

bospy

python wrappers for accessing bos services.

Points are accessed via "pointers". You get a pointer by using a query function like NameToPoint and pass the output to a function like Get or Set.

Pointers are the uri strings that uniquely identify each point in the sysmod.

Get

Get(points) takes one or more point uris and returns values for each uri passed.

Getting a single point by name:

name = 'BLDG3.AHU2.RM1.TEMP'
pt = NameToPoint(name)
value = Get(pt)
print(name, value)

Output:

$ python get_example.py
BLDG3.AHU2.RM1.TEMP 18.0

Getting multiple values by location:

pts = LocationToPoint('ROOM_1')
resp = Get(pts)
for k, v in resp.items()
    name = GetPointName(k)
    print(name, v)

Output

$ python get_multiple_example.py
BLDG3.AHU2.RM1.TEMP 22.5
BLDG3.AHU2.RM1.SETPOINT 21.0
BLDG3.AHU2.RM1.DAMPER_POS 85.0

Set

Set(points, values) takes 1 or more point uris and an equal number of values. You may also pass a single value to be written to all points.

Usage:

pt = GetPointByName('BLDG3.AHU2.RM1.SETPOINT')
ok = Set(pt, 23)
if ok:
    print('success')
else:
    print('failed to write', key)

Output:

$ python set_example.py
success
