Arduino UNO ? W5100 LAN module ? 433-module ? RTC-module (DS3231) ? Self-learning power switches Added functionality: ? Daylight Saving Time for CET ? Sunset/Sunrise calculation The RTC-module (DS3231) is added for two reasons. ? Unaware if the time can be retrieved from Cheyenne ? Store in the alarm if we are on DST-time or not Some lines are set to comment, you can use this section to reset your RTC-module and/or to set a new time. In this section you also “give the “DTS_check the initial correct value; DST in CET is calculated a bit odd). ## Triggers & Alerts The Present time, sunrise and sunset are used to calculate if it is night time or not: if (time_now >= time_sunset or time_now <= time_sunrise) { and saved as a digital sensor. This sensor is used in a trigger to switch light on/off at sunset/sunrise. ## Scheduling Sunset and sunrise is calculted daily at 2 AM. Some lights will switch off at pumkin time (others on sunrise done with a trigger). ## Dashboard Screenshots The dashboard: ![](https://discourse-cloud-file-uploads.s3.dualstack.us-west-2.amazonaws.com/business5/uploads/mydevices/original/2X/b/b5554dd50bb9d29c089187f8889052929507b217.JPG) Trigger: ![](https://discourse-cloud-file-uploads.s3.dualstack.us-west-2.amazonaws.com/business5/uploads/mydevices/original/2X/9/99191931578c2202da084ae8f2e9442254c2d7d8.JPG) **Original links:** - - **Relational links:** - - --- Source: https://maker.wiznet.io/rena/projects/Home-Automation-with-Selflearning-433-Power-Switches/
