OWSTC is an Open Source project performing as a programmable timer switch for One Wire technology addressable switches such as DS2408 (8-Channel Addressable Switch) or DS2413 (Dual Channel Addressable Switch).

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.
• 7-day programming: time programs are valid only for selected days of the week
• Time programs may be valid for a specified time period only.
• Each switch may be in one of the three modes: constant ON, constant OFF, TIMER. Mode may be set without affecting the programming of the timer.
• Option to automatically delete time program after it's expiry date.
• Option for time program to override other active time programs when switching OFF.

Web interface

• Management of time programs (insert, update, delete)
• Designed for usage on smart phone
• Cloning of time programs
• Interruption of time programs for a given time period (ideal for holidays etc.)
• Immediate action: switch ON for given time, switch OFF in given time.
• Access to log
• Display of at queue

The script which actually switches on or off the One 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 to 59 seconds to late/early.
