Python wrapper around the request/response API for the UHPPOTE TCP/IP access controllers.
A demo CLI illustrating the use of the API can be found in the examples/cli folder.
pip install uhppoted
v0.8.9 - 2024-09-06
- Enabled per-controller operation timeout configuration.
- Added support for TCP connections.
Invoking an API function requires an instance of the Uhppote class initialised with the information required
to access a controller:
class Uhppote:
def __init__(self, uhppote=None):
where uhppote is an instance of
class UHPPOTE:
bind: str
broadcast: str
listen: str
debug: bool
bind IPv4 address to which to bind the UDP socket. Defaults to 0.0.0.0
broadcast IPv4 address:port for broadcast UDP packets. Defaults to 255.255.255.255:60000
listen IPv4 address:port for events from controller (unused). Defaults to 0.0.0.0:60001
debug Displays the controller requests/responses if true.
e.g.:
from uhppoted import uhppote
from pprint import pprint
bind = '0.0.0.0'
broadcast = '255.255.255.255:60000'
listen = '0.0.0.0:60001'
debug = True
u = uhppote.Uhppote(bind, broadcast, listen, debug)
record = u.get_controller(405419896)

- All API functions raise an
Exceptionif the call fails for any reason whatsoever. - All API functions (other than
get_controllersandlisten) take acontrollerthat may be either:- a _uint32_s controller serial number (legacy)
- a tuple comprising
(id,address,protocol), whereidis the (required) controller serial numberaddressis the (optional) controller IPv4 address or address:portprotocolis the (optional) transport protocol ('udp' or 'tcp') e.g.:
get_controller(405419896)
get_controller((405419896, '192.168.1.100', 'tcp'))
