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

• completely free and open source.
• manages all configured channels of adressable switches in a 1-Wire network.
• every switch can be controlled by timer programs.
• Everey 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.

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.
• 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 starting and final date.
• 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 actions such as switch-ON for given time or 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.
