Web for old phones through a Raspberry Pi

How to Contribute

You can write yout own service as a backend quite easily. Look at the tutorial HOWTO.

Goals

Task1: I text to my Raspberry some question, I receive its answer within a minute.

Some examples:

• "train next departure StationA" -> "request received at 13h45: next departure from StationA at 14h15, following one at 15h45"
• "bikes Railway Station" -> "request received at 17h46: there is 6 bikes left and 5 free slots at the bike station next to the railway station"
• "train from Paris to Marseille 13th March -> list of trains and prices
• "bank amount [passphrase]" -> amounts of your bank accounts
• "forecast Marseille 14th March" -> precise forecast
• "Gmail subjects list" -> list of (id,subject of id's email)
• "Gmail body 3" -> body of email whose id=3
• "movie Mommy Paris 18" -> next film show of Mommy around Paris 18
• car trafic (e.g., bison futé in France)
• train trafic (e.g., infolignes)
• best restaurants around for giving cuisine (e.g. chinese, indian, ...)
• roadmap for cars (given as a list if directions to follow)

Task2: add the ability to set up SMS notifications for a given request. For instance, we may need to receive a SMS as soon as:

• a delay is expected for a given metro line or
• the last bus/metro/wheteveror of the night is expected at a given place in less than 15 minutes or
• the amount of a bank account becomes negative or lower than X, ...

Task3: I let a voicemail on my raspberry's number with my request, it answers me by SMS.

Tech

Hardware: a Sim Card reader (I bought mine 20€ here), a Sim Card with a 0euro phone plan (e.g., Prixtel in France) only used to receive SMSs, a raspberry Pi. In order to send free SMSs, we use a common feature of most of mobile operators: by sending an email to [phone number]@[mobile operator website], the email is forwarded by SMS to [phone number].

Software: project Weboob (scriptable routines for fetching info from websites), Python and Google scripts to glue everything together. We use Gammu to interact with the SIM card reader.

Roadmap

1. Task1, focus on train and bikes, interacting with the raspberry pi by letting a voicemail (0 or 1) -> DIRECTLY TASK 2
2. 1. • interacting using SMSs
3. Task2

webtext's Issues

Add a RATP backend

By fetching information from RATP, Vianavigo, http://www.transilien.com/ or whatever, we should write a backend that could answer to requests of the form:

ratp depa luxembourg             (next departures)
ratp depa luxembourg; orly       (next departures for a given direction)
ratp traf rer                    (trafic)
ratp traf metro
ratp itiner luxembourg; porte de vincennes  (roadmap)

We may use https://github.com/laurentb/weboob, https://github.com/pgrimaud/horaires-ratp-api or https://github.com/radium226/vianavigo.

[Yelp] new backend

Best restaurants of a given type around a given location (with an optional max distance).
Example: "yelp; indian; 10 rue Pajol, 75018; 2km".

Using the Yelp Api and this piece of code.

[sncf] new backend

Live information for a given train (platform, delay, etc.). Basically all information that the SNCF Direct app provide.
Ex. "sncf; 12454".

We may use this API.
