synopsis

ACKbot zit in ons IRC-kanaal #ackspace op irc.freenode.org. Met het commando !status geeft het aan of de space gesloten of geopend is.

update september 2015

Inmiddels is de bot een tijdje offline geweest en heeft xopr proberen nieuw leven in de bot te blazen. Samen met de code van de mobile Spacestate Indicator om de JSON te parsen, en de vernieude SpaceAPI zijn temperatuursensors toegevoegd en is het makkelijker om de bot uit te breiden met nieuwe commando's.

software

ACKbot_v1.2.py

De geüpdate versie van xopr. Deze kan ook naar privéberichten luisteren (/msg) De commando's zijn:

!status of !state: laat de status van de space zien en het tijdstip waarom deze gewijzigd is

!temp: laat de laatst gemeten temperaturen zien en wanneer deze gemeten zijn

!help: geeft een kort overzicht van de commando's
