Plant Watering

This recipe combines a momentary button and a timer to control a relay that is switched on for 5 min. 3 times a day. This can be used to control a valve for watering plants.

The central element is a switch that controls a relay on a digital output. There are 3 sources that can control the switch

1. In the web UI the switch is shown and can be switched to start/stop the relay.
2. The momentary button on the digital input can also be used to toggle the switch.
3. The timer switches the switch on for 5 min every 8 hours.
