EDIPLUG-PY - Python Class for EDIMAX Smart Plug Switch SP-1101W

2016-26-01 Stefan Wendler sw@kaltpost.de

Simple Python class to access a "EDIMAX Smart Plug Switch SP1101W/SP2101W". Supports simple switching as well as programming the schedule of the plug and reading power and current consumption. The class could be used as an API or as command line utility:

Important note: I think the library does not work with newest FW versions. Only FW versions which connect to EdiPlug App work. The ones connecting to EdiSmart use a different protocol. The latest versions working are:

• SP1101W: v2.02
• SP2101W: v2.03

Requirements

• Python 2.7
• The requests library (e.g. use pip install requests)

Use as command line utility

General:

• To specify the hostname or IP address of the plug us the -H <host-or-ip> parameter.
• To pass along the login for the plug use -l <login>.
• To set the password for the login user -p <password>

Get device info:

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -i

Turn plug on:

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -s ON

Turn plug off:

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -s OFF

Get plug state:

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -g

Get power consumption (only SP2101W)

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -w

Get current consumption (only SP2101W)

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -a

Get schedule of the whole week (human readable):

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -G

Get schedule of the whole week (python array):

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -P

Set schedule for one day:

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -S "{'state': u'ON', 'sched': [[[11, 0], [11, 45]]], 'day': 6}"

Set schedule for the whole week:

python smartplug.py -H 172.16.100.75 -l admin -p 1234 -S "[
    {'state': u'ON', 'sched': [[[1, 0], [1, 1]]], 'day': 0},
    {'state': u'ON', 'sched': [[[2, 0], [2, 2]]], 'day': 1},
    {'state': u'ON', 'sched': [[[3, 0], [3, 3]]], 'day': 2},
    {'state': u'ON', 'sched': [[[4, 0], [4, 4]]], 'day': 3},
    {'state': u'ON', 'sched': [[[5, 0], [5, 5]]], 'day': 4},
    {'state': u'ON', 'sched': [[[6, 0], [6, 6]]], 'day': 5},
    {'state': u'ON', 'sched': [[[7, 0], [7, 7]]], 'day': 6},
]"

Use as API

For reference, there are the following examples:

• turn the plug ON and OFF
• query week schedule
• set the schedule of one day
• set the schedule of one week
• read device info
• connect the plug to Blynk

General API usage is as follows.

Import:

from ediplug.smartplug import SmartPlug

Create plug object:

p = SmartPlug("172.16.100.75", ('admin', '1234'))

Get device info

print(p.info)

Turn plug off:

p.state = "OFF"

Turn plug on:

p.state = "ON"

Query and print current state of plug:

print(p.state)

Get power consumption (only SP2101W)

print(p.power)

Get current consumption (only SP2101W)

print(p.current)

Read and print complete week schedule from plug:

print(p.schedule.__str__())

Write schedule for on day to plug (Saturday, 11:15 - 11:45):

p.schedule = {'state': u'ON', 'sched': [[[11, 15], [11, 45]]], 'day': 6}

Note: 0 - Sunday, 6 - Saturday

Write schedule for the whole week:

p.schedule = [
    {'state': u'ON', 'sched': [[[0, 3], [0, 4]]], 'day': 0},
    {'state': u'ON', 'sched': [[[0, 10], [0, 20]], [[10, 16], [11, 55]], [[15, 19], [15, 32]], [[21, 0], [23, 8]], [[23, 17], [23, 59]]], 'day': 1},
    {'state': u'OFF', 'sched': [[[19, 59], [21, 1]]], 'day': 2},
    {'state': u'OFF', 'sched': [[[20, 59], [21, 12]]], 'day': 3},
    {'state': u'OFF', 'sched': [], 'day': 4},
    {'state': u'OFF', 'sched': [[[0, 0], [0, 30]], [[11, 14], [14, 31]]], 'day': 5},
    {'state': u'ON', 'sched': [[[1, 42], [2, 41]]], 'day': 6}]

Complete examples could be found in the examples directory. Don't forget to set your python path properly. E.g. when running the 1st exmaple from the projects main directory:

PYTHONPATH=./src
python ./src/examples/sample_01.py
