geniushub-client

This is a Python library to provide access to a Genius Hub by abstracting its RESTful API. It uses aiohttp and is therefore async-friendly.

This library can use either the offical v1 API with a hub token, or the latest v3 API (using your own username and password). In either case, the library will return v1-compatible results wherever possible (this is not a trivial task).

If you use the v3 API, you can interrogate the hub directly, rather than via Heat Genius' own servers. Note that the v3 API is undocumented, and so this functionality may break at any time. In fact, the v3 to v1 conversion if best efforts and may even be broken as is for some edge cases - it was tested with HW, on/off (i.e. smart plugs), and radiators only.

It is a WIP, and may be missing some functionality. In addition, there are some other limitations (see below).

It is based upon work by @GeoffAtHome and [@zxdavb]](https://github.com/manzanotti/geniushub-client/commits?author=zxdavb) - thanks!

Current limitations

Current limitations & to-dos include:

Thus, always check your output against the corresponding v1 API response rather than the web app.

Installation

Either clone this repository and run python setup.py install, or install from pip using pip install geniushub-client.

Using the Library

See ghclient.py for example code. You can also use ghclient.py for ad-hoc queries:

python ghclient.py -?

There are two distinct options for accessing a Genius Hub:

Option 1: hub token only:

Option 2: hub hostname/address with user credentials:

HUB_TOKEN="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCIsInZlc..."
HUB_ADDRESS="my-geniushub.dyndns.com"
USERNAME="my-username"
PASSWORD="my-password"

python ghclient.py ${HUB_TOKEN} issues

python ghclient.py ${HUB_ADDRESS} -u ${USERNAME} -p ${PASSWORD} zones -v

You can compare any output to the 'official' API (v1 response):

curl -H "authorization: Bearer ${HUB_TOKEN}" -X GET https://my.geniushub.co.uk/v1/zones/summary
python ghclient.py ${HUB_TOKEN} zones

curl -H "authorization: Bearer ${HUB_TOKEN}" -X GET https://my.geniushub.co.uk/v1/devices
python ghclient.py ${HUB_ADDRESS} -u ${USERNAME} -p ${PASSWORD} devices -v

curl -H "authorization: Bearer ${HUB_TOKEN}" -X GET https://my.geniushub.co.uk/v1/issues
python ghclient.py ${HUB_ADDRESS} -u ${USERNAME} -p ${PASSWORD} issues

You can obtain the 'raw' v3 API responses (i.e. the JSON is not converted to the v1 schema):

python ghclient.py ${HUB_ADDRESS} -u ${USERNAME} -p ${PASSWORD} zones -vvv
python ghclient.py ${HUB_ADDRESS} -u ${USERNAME} -p ${PASSWORD} devices -vvv

To obtain the 'official' v3 API responses takes a little work. First, use python to obtain a HASH:

>>> from hashlib import sha256
>>> hash = sha256()
>>> hash.update(("my_username" + "my_password").encode('utf-8'))
>>> print(hash.hexdigest())
001b24f45b...

Then you can use curl:

curl --user ${USERNAME}:${HASH} -X GET http://${HUB_ADDRESS}:1223/v3/zones

Advanced Features

When used as a library, there is the option to utilize the referencing module's own aiohttp.ClientSession() (recommended).

Here is an example, but see ghclient.py for a more complete example:

import asyncio
import aiohttp
from geniushubclient import GeniusHub

my_session = aiohttp.ClientSession()

...

if not (username or password):
    hub = GeniusHub(hub_id=hub_address, username=username, password=password, session=my_session)
else:
    hub = GeniusHub(hub_id=hub_token, session=my_session)

await hub.update()  # enumerate all zones, devices and issues

hub.verbosity = 0  # same as v1/zones/summary, v1/devices/summary
print(hub.zones)

hub.verbosity = 1  # default, same as v1/zones, v1/devices, v1/issues
print(hub.devices)

print(hub.zone_by_id[3].data["temperature"])
print(hub.device_by_id["2-2"].data)

await my_session.close()

Unit tests

Please see the README.md file in the tests folder for more details on unit tests protocol.

QA/CI via CircleCI

QA includes comparing JSON from cURL with output from this app using diff, for example:

(venv) root@hostname:~/$ curl -X GET https://my.geniushub.co.uk/v1/zones -H "authorization: Bearer ${HUB_TOKEN}" | \
    python -c "import sys, json; print(json.dumps(json.load(sys.stdin, parse_float=lambda x: int(float(x))), indent=4, sort_keys=True))" > a.out

(venv) root@hostname:~/$ python ghclient.py ${HUB_ADDRESS} -u ${USERNAME} -p ${PASSWORD} zones -v | \
    python -c "import sys, json; print(json.dumps(json.load(sys.stdin, parse_float=lambda x: int(float(x))), indent=4, sort_keys=True))" > b.out

(venv) root@hostname:~/$ diff a.out b.out
