PAssist is an Android application to assist you while doing on-call duties. The name PAssist is the short form of Pikett-Assist ('Pikett' is the Swiss German term for on-call).
PAssist works for SMS based alerting systems.
App language translations maintained with the great localization platform Lokalise.
PAssist activates and deactivates itself based on your calendar. All supervision features are only running, when PAssist is activated. PAssist activates some time (configurable pre-/ post-run time) before and keeps activated some time after the events start and stop time. This ensures you won't miss an alert in case of a small time discrepancy between the operations center time and your phone time. All calendar events matching a configured title pattern are considered as on-call events. PAssist shows you an overview with all future on-call events on the calendar tab.
If an SMS is received from your configured operations center, PAssist will race an alert. It is playing a configured ringtone and starts a vibration pattern until you confirm it with a swipe button. When confirmed, an acknowledge SMS is send back to your operations center. The alarm goes into the confirmed alarm state and can be finally closed when all your support activities are completed.
PAssist creates an alarm log with the start and end time of each incident. All SMS messages received between start and end time are attached to the alarm in the log. On the alert log tab you see all your passed alerts in an overview. Selecting an entry shows the details of an alert incident including current state, reaction time to confirm, duration from start to end and all received SMS messages. The alert log can be exported/imported from/to the external file system.
PAssist will supervise the phone signal strength and notifies you with a vibration pattern if the signal strength is bad or off (includes airplane mode). This ensures that you won't stay in a dead spot without recognize it during on-call duties.
PAssist will supervise the battery level and notifies if it is below a configured minimum level.
PAssist can control the ringtone volume during on-call duty with separate profiles for day and night.
If the SMS alarming system in use sends daily test alarms to verify the alarming chain from end to end, PAssist can be configured to automatically receive and acknowledge them, without interrupting the user. On a configured daily check time, PAssist verifies if the expected test alarms have been received. If not, PAssist will race an alert with a configured ringtone and starts a vibration pattern until you confirm the missing test alarm with a swipe button. Test alarms can be configured for different contexts, as your alarming system may send a test alarms for various systems that are under supervision.
PAssist can be installed from Google Play or IzzyOnDroid.
Build PAssist on your own and then install the APK via ADB to your android phone.
In order to perform the functions of PAssist, PAssist needs to be able to receive and send SMS. As these SMS permissions are no more granted by Google, a compatible SMS adapter is required.
Currently the only supported SMS adapter is secure-sms-proxy. PAssist will guide you to install this SMS adapter.
Defines the contact of your operations center sending alarms via SMS. The SMS received from any phone number of this contact are supervised by PAssist.
PAssist also supports operations centers using alphanumeric short code SMS numbers. As contacts in Android cannot use letters in phone numbers, such alphanumeric short codes can be configured in the contact field "Company". It the operations centers uses several alphanumeric short codes, they can be comma separated in the contacts company field.
Be aware that confirmation replies are not possible if alphanumeric short code SMS numbers are used.
Enable or disable whether confirmation replies should be sent back to the operations center. If the warning system of your operations center does not support confirmation messages, you can deactivate this setting to save the cost of sending the extra reply SMS.
Defines the text to send back as alarm acknowledgement to your operations center.
Regular expression pattern to identify SMS messages
to be ignored.
If empty, SMS filtering is disabled.
WARNING: Be careful, if the pattern is not well designed and triggers for a real alarm, you won't be alerted!
Defines the ringtone that is used to alert for on-call alarms.
Defines one specific or all of your calenders, that should be used to look for on-call events.
Defines a Regular expression pattern (case insensitive) to match the titles of your calendar events, which should be considered for your on-call duties.
Defines whether partner contacts are extracted from on-call duty events.
Defines a Regular expression pattern to
extract partner contacts from on-call duty events.
The partner contacts are extracted from the notes field of on-call duty events.
There can be several partner contacts in the event notes.
The extracted partner contacts are interpreted as contact nicknames.
Time in seconds to enable/disable the on-call state before and after the calender event. The default is 300 seconds (five minutes).
Defines whether the signal strength is supervised or not. In case the battery level falls below 10% the check interval is reduced in favour of a longer remaining term.
Defines the lowest accepted signal strength level.
Defines the amount of seconds for which the signal strength must be lower than the minimal expected level before a low signal alarm is raced. With filtering you can reduce false alarms. The filter can be set between 0 (filtering off) and 10 minutes, with a default of 30 seconds. Be aware: With higher values, it takes longer until you are notified of a dead spot. Even with filtering enabled, the airplane mode is detected immediately.
Defines whether an alert for low signal strength creates a notification or not. The phone also shows a low signal strength through a vibration pattern, regardless of this setting.
For dual SIM phones you can select the subscription for which the signal strength is supervised.
Defines whether the battery level is supervised or not.
Defines the minimal battery level in percentage (between 10% - 50%). If the current battery level falls below this minimal level, a alert notification is created. Independent of the this minimal battery level, whenever the battery level is in the danger zone (below 10%) the polling interval for PAssist checks (e.g. signal strength) is lowered to minimize the power consumption.
Enable or disable the test alarm feature.
Regular expression pattern to identify SMS alarm messages as test alarms (case sensitive).
WARNING: Be careful, if the pattern is not well designed and triggers for a real alarm, you won't be alerted!
The regular expression can define a group to extract the test context (for example the name of the system) out of the SMS. As an example the following regular expression could handle test alarms from two different systems 'Helios' and 'Lunar':
^Test alarm for system (Helios|Lunar).*
Test alarms of each group can be supervised individually.
Defines which of the available test contexts should be supervised.
Defines the daily time on which the check occurs whether the test alarms have been received recently or not.
Defines the time window in which the test alarm must have been received before the check time to be accepted.
Defines the weekdays on which the test alarms are checked.
Defines the ringtone that is used to alert for missing test alarms.
Time when day/night profile starts.
Defines whether PAssist should control the ringtone volume during on-call duty or not. The desired ringtone volumes can be defined for the day and night profile separably. If activated, the ringtone volume is automatically restored to the former value, when on-call duty is finished.
Enable "Minimize at night" to reduce power drain at night by reducing the check interval for the signal strength monitoring.
