OWST is an Open Source project performing as a programmable timer for 1-Wire(R) switches such as DS2408 (8-Channel Addressable Switch) or DS2413 (Dual Channel Addressable Switch).

• Completely free and open source.
• Manages addressable switches in a 1-Wire network, every switch can be controlled by separate timer programs.
• Every switch may be in one of the three modes: constant ON, constant OFF, TIMER. Mode may be changed without affecting the programming of the timer.

• Nearly unlimited time programs. Number of time programs are limited only by the resources of the server and/or the used database management system SQlite3.
• Time programming is based on weekly repetition.
• 7-day programming: time programs can be set to be valid for selected days of the week only.
• Time programs can be limited by a start and end date.
• Option to automatically delete time program after it's end date.
• Option for time program to override other active time programs when switching OFF.

• Management of time programs (insert, update, delete)
• Cloning of time programs
• Interruption of time programs for a given time period (ideal for holidays etc.)
• Immediate actions such as switch-ON in given time for a given time (e.g. switch on in 00:30 for 02:15) or switch-OFF in given time (e.g. switch off in 01:45).
• View log
• View 'at' queue

The script which actually switches on or off the 1-Wire switches may be called periodically using cron or at the corresponding date and time using 'at' (with automatic reprogramming of 'at').

OWS Timer Control works on a time resolution of minutes. Therefore time programs might switch off/on up too 59 seconds to late/early.
