fx = BAC0.device('16102:19', 1610219, bacnet, object_list = my_obj_list)

p=fx.points

for point in p:

    print(point)

The code is returning the point values as expected, but throwing an exception. Can not figure out what I'm doing wrong.

I've made some tests trying to replicate your bug and I think you may be fighting with a weird device.

Using the exact same script I succeed reading all points.

If I may suggest though, declaring your device using default "poll" parameters will assure reading of all points every 10 seconds.

Using points will force a reading of points (one by one) when called which will slow the process. For that, I would use point.lastValue

When the device polls its point list, internally, it'll use a ReadPropertyMultiple that will read a bunch of points and properties at the same time. It is more efficient.

Something like (playing with format...) :

import BAC0



bacnet = BAC0.lite()



# # Provide it as an argument

fx = BAC0.device('2:5', 5, bacnet)



for name in fx.points_name:

    if fx[name].units:

        val = '{:>10.2f}'.format(fx[name].lastValue)

        units = fx[name].units

    else:

        units = '({})'.format(fx[name].properties.units_state)

        val = '{:>10}'.format(fx[name].lastValue)

    print('{:<20} : {} {:<10}'.format(fx[name].properties.name, val, units))
