CellCius is an automatic low-balance notification tool for the Cell-C mobile network in South Africa. CellCius ======== CellCius is an automatic balance checking and low-balance notification tool for the Cell-C mobile network in South Africa. Receive email warnings when one of your balances (Voice Minutes, Data MB or SMSes) drops below configurable thresholds. The script can make use of either gmail or a local MTA to send the warning emails. You can configure how frequently you want to receive the warning emails (ie. Every 5 hours) in the settings file. View settings.py for more info on configuring. CellCius is a robust, retrying (with exponential backoff), long running process. WHY? ---- Because knowledge is power. Having this running in the background means that I never run out of airtime at an awkward momement, or end up without data needed to buy more data. Also, not receiving warnings means that once your data bundle is up, you'll chew through your remaining "airtime" at 99c per mb instead of the in-bundle 15c. Shouldn't Cell-C be sending these kinds of alerts? YES! INSTALLATION: ------------ * Setup your Cell-C "My Account" at cellc.co.za * Copy settings.py.sample to settings.py and configure accordingly. * Run "python cellcius.py" to confirm it's running correctly. * Run it inside a Screen session or get fancy with startupd etc. Dependencies: Use VirtualEnv and `pip install -r requirements.txt` * requests (HTTP for Humans) * lxml (for parsing HTML) * retrying (Elegant retrying with exponential backoffs) HOW DOES IT WORK? ----------------- The script jumps through some hurdles to complete the single sign on, then calls a page that returns some badly formatted (unstructured) text, which is then parsed using regex. It keeps the session open so you'll only receive an SMS from Cell C confirming your login when the application first starts up, CellCius then polls the site (using the existing session) every 9 minutes. If the sesssion dies (ie. Cell-C reboot their servers?) it will detect the lost session and recreate it, at …
