pyrehau_neasmart

A python 3 package to interact with Rehaut Nea Smart interface

What is Nea Smart Manager ?

If you are not familiar with the product "Nea Smart" from Rehau, this package won't be very useful for you ;).

Nea Smart Manager is an interface which allows you to control your Rehau electronic thermostat.

More informations here : https://www.rehau.com/en-en/nea-smart/english / https://www.rehau.com/download/1558632/nea-smart-manager-notice-d-installation-et-d-utilisation.pdf

Here is the interface provided by Rehau :

The problem : Nea Smart doesn't expose any public API. We need to play with the Nea Smart interface. If you check your web console, you'll see this : http://neasmart_ip/data/cyclic.xml. It's an XML file with all the information you need. If you want to do some changes, you can post an XML form to /data/changes.xml, with no authentication.

Basically, this python package is a wrapper for this weird API.

Installation

pip install pyrehau_neasmart

Changelog

See CHANGELOG.md

To Do / Done :

• Wrapper for xml documents
• Get HEAT AREAS
• Get IODEVICES
• Get heatareas's schedules
• Modify (POST) some informations (modify the heat area's wanted temperature)
• Logs ?
• Feel free to submit an issue ;).

Usage

Set the right IP address, and nothig more.

By default, properties will be refreshed by querying NeaSmart only if last refresh was more than 1 second ago. Pass "auto_update=False" to disable that behavior (in which case you'll need to call update_status() yourself).

from pyrehau_neasmart import RehauNeaSmart

rh = RehauNeaSmart('192.168.1.18')
# rh = RehauNeaSmart('192.168.1.18', auto_update=False)

List of heatareas

>>> rh.heatareas()
[<pyrehau_neasmart.RehauNeaSmartHeatarea object at 0x7f634adf6860>, <pyrehau_neasmart.RehauNeaSmartHeatarea object at 0x7f634adf65f8>, <pyrehau_neasmart.RehauNeaSmartHeatarea object at 0x7f634adf6668>, <pyrehau_neasmart.RehauNeaSmartHeatarea object at 0x7f634adf66a0>, <pyrehau_neasmart.RehauNeaSmartHeatarea object at 0x7f634adf6630>]

# See below for RehauNeaSmartHeatarea object

Select a heatarea and get informations

>>> my_heatarea = rh.heatareas()[0]

>>> my_heatarea.status
{ 'heatarea_mode': '2',
  'heatarea_name': 'ChBlanche',
  'heatarea_state': '0',
  'islocked': '0',
  'party': '0',
  'party_remainingtime': '0',
  'presence': '0',
  'program_source': '0',
  'program_week': '1',
  'program_weekend': '1',
  't_actual': '22.0',
  't_actual_ext': '22.0',
  't_target': '18.0',
  't_target_base': '18.0'}

Every property you'll get in status in directly callable :

>>> my_heatarea.t_actual
'23.4'
>>> my_heatarea.program_week
'2'

Change the target temperature for a heatarea

>>> ha = rh.heatareas()[4]
>>> ha.set_t_target(18)

Change the heat area mode for a heatarea

>>> ha = rh.heatareas()[4]
>>> ha.set_heatarea_mode(2)
