EspIrrigation is a irrigation controller based on the Homie-Framework. It can control up to 16 valves in either auto or manual mode. In manual mode the valves can be opened individually and in auto mode the valves open in a specific order. The durations of each valve can be programmed and are also available after power loss as they are stored in the EEPROM of the ESP8266.
EspIrrigation provides the following nodes as ranges from 1 to NUM_VALVES. n is the corresponding valve.
valve/open_n: (true|false)valve/duration_n: time in secondsvalve/order_n: [0-NUM_VALVES]
The open nodes define whether the corresponding valves are opened or closed. If the node is set to true the valve is opened for the given time, else if the node is set to false the valve closes immediately.
The duration nodes define the duration a valve is opened. These durations apply in auto mode as well as in manual mode.
The order nodes define the order the valves are opened in auto mode. Only the first order elements greater than 0 are taken into account.
Example:
valve/order_1: 2valve/order_2: 1valve/order_3: 0valve/order_4: 3
In auto mode the first valve opened is valve number 2, followed by valve number 1. All order elements after order_3 are not taken into account as order_3 is 0 and thus stops the auto mode.
