Hackerspace Wroclaw Alarm Bot

Warning: this is a proof of concept, don't rely on it

It was very basically tested, and while it seems to work, approach it without any expectations. In other words - treat it as a toy, not as a tool that will save your life or valuables, because it probably won't.

Usage

$ TELEGRAM_APITOKEN=YOUR_API_TOKEN ./alarm_bot --satel_addr=127.0.0.1 --satel_port=31337 --tg_chat_id=YOUR_CHAT_ID_FROM_BOTFATHER

Notification via HTTP callbacks

Set the following environment variables:

NOTIFY_URL_ARM - for an URL that will be POST when partition 0 is armed
NOTIFY_URL_DISARM - for an URL that will be POST when partition 0 is unarmed
ALARM_URL_ARM - for an URL that will be POST when any partition alarm is activated

Filtering events by change type

It's possible to filter events by change type. Use the --allowed-types=TYPE1,TYPE2,... command line parameter to do that. If that parameter is not provided, then all change types are allowed, otherwise only the provided ones will be used for notifications.

Supported types are:

zone-violation
zone-tamper
zone-alarm
zone-tamper-alarm
zone-alarm-memory
zone-tamper-alarm-memory
zone-bypass
zone-no-violation-trouble
zone-long-violation-trouble
armed-partition-suppressed
armed-partition
partition-armed-mode-2
partition-armed-mode-3
partition-with-1st-code-enter
partition-entry-time
partition-exit-time-over-10s
partition-exit-time-under-10s
partition-temporary-blocked
partition-blocked-guard-round
partition-alarm
partition-fire-alarm
partition-alarm-memory
partition-fire-alarm-memory
output
doors-opened
doors-opened-long
status-bit
trouble-part-1
trouble-part-2
trouble-part-3
trouble-part-4
trouble-part-5
trouble-memory-part-1
trouble-memory-part-2
trouble-memory-part-3
trouble-memory-part-4
trouble-memory-part-5
partition-with-violated-zones
zone-isolate

Filtering events by index (which meaning depends on the change type)

Use the --allowed-indexes=1,2,3,... command line parameter to set the list of allowed indexes (of course provide your own list instead of 1,2,3,...). If that parameter is not provided, then all indexes are allowed; otherwise the notification is sent for all indexes.

Set the OMIT_TG environment variable to, well, omit sending anything over to Telegram and just see the logs instead.
