Het Eversdijk familiewapen

Het geslacht Van Eversdijk dat voornamelijk op Zuid-Beveland gevestigd is, draagt zijn naam naar de ambachtsheerlijkheid Eversdijk. Cornelis was de kleinzoon van Dignus Cornelisse Eversdijk, baljuw van Hoedekenskerke (ca 1553), gehuwd met Geertruida, dochter van Willem, bastaard van Heenvliet.

Garden sprinkler control system

For my home automation system i'm busy building an automated garden sprinkler system. The system determines the sprinkling needs based on the current weather conditions and predictions.

The  garden sprinkler controller consists out of two systems

1) A Vera2 home automation controller as supplied by MiCasaverde (http://micasaverde.com/vera.php)

The Vera box is the master off the sprinkler system and determines the sprinkler needs, depending on the weather prediction as supplied by Google's weather API. (demo) This API provides the current weather conditions and the weather prediction for the next 5 days. For this purpose i've developed a new MiOS LUUP plugin heavily inspired on the Weather Plugin from "guessed" The Vera module provides also a setting dialog to configure the valve control unit (see system 2), sprinkler duration, time, weekdays etc.

2) A Netzer Ethernet PIC module from Sven Schlender (http://www.mobacon.de/Netzer/)

The Netzer module provides the Ethernet gateway between the Vera box and the Pump/Valve relays. The Netzer module also acts as a local control unit (start/stop buttons) and a watchdog preventing the sprinkler keeps pumping when the connection is lost. The Netzer - sprinkler system can be controlled through URL commands. For this purpose i've added a 'Sprinkler web'-page to the Netzer.

Both the MiOS LUUP plugin as the Netzer ROM code can be downloaden from the download area at this website.

(The Netzer ROM code is based on Netzer version 1.1 as provided by Elektor)

 

 

MiOS Vera plug in

To be able to controll the Sprinker - Netzer a plug in is made heavily inspired on the Weather Plugin from "guessed".

See a number of screen shots below.

 

 

 

Netzer module

Around the Netzer module, a number of relais are mounted.Sprinkler webpage

  • 1 Pump relais (at Pin GPIO 0)
  • 2 Valve relais (at Pin GPIO 1 & GPIO 2)

There also 4 switch buttons inputs wired

  • button 1 to  start pump only (at Pin GPIO 4)
  • button 2 to  start pumping with valve 1 (at Pin GPIO 5)
  • button 3 to  start pumping with valve 2 (at Pin GPIO 8/SPI CS)
  • button 4 to  toggle through the operation modes (block, auto and manual) (at Pin GPIO 8/SPI INT)

 


To provide additional information 2 led are installed a green led (at Pin GPIO B/SPI CLK) and a red led (at Pin GPIO A/SPI MISO).

 

The Sprinkler systems has serveral operation modes:

  • SPRINKLER_NO_CONNECTION  = -1 -- no connection possible with device
  • SPRINKLER_MODE_NOT_INIT   = 0 -- not initialised (fast blink RED and fast bilnk GREEN)
  • SPRINKLER_MODE_BLOCK  = 1  -- Not sprinkler possible block pump valve (RED on and GREEN off)
  • SPRINKLER_MODE_MANUAL   = 2  -- Manual sprinkling  (blink RED and GREEN off)
  • SPRINKLER_MODE_NORMAL  = 3 Normal sprinkling = AUTO (RED off and GREEN off)
  • SPRINKLER_MODE_WET  = 4  -- Wet period no spray required (RED off and GREEN off)
  • SPRINKLER_MODE_SPRAY_TODAY = 5  -- We will spray today (RED off and blink GREEN )
  • SPRINKLER_MODE_SPRAY_SKIPPED  = 6  -- We did miss out spray slot today (RED off and fast blink GREEN)
  • SPRINKLER_MODE_SPRAYING_DONE  = 7 -- We did spray today (RED off and GREEN on)
  • SPRINKLER_MODE_SPRAYING_STOPPED   = 8  -- We interrupted spraying today (RED off and fast blink GREEN)
  • SPRINKLER_MODE_SPRAY_ADVICE   = 9 -- Manual mode, but spraying is adviced (blink RED and fast blink GREEN)
  • SPRINKLER_MODE_ERROR  = 10 -- Some kind off error (RED and GREEN toggle)

 


To access the Sprinkler Netzer one can use a webbrowser

 

To controll the Sprinkler Netzer one can use the following url's:

  • http://{netzer-ip}/sprinkler.cgi?start=1 == start sprinkling with Valve 1 (close valve 2) for the a pre configured time
  • http://{netzer-ip}/sprinkler.cgi?start=2&timeout=20 == start sprinkling with Valve 2 (close valve 1) for 20 minutes
  • http://{netzer-ip}/sprinkler.cgi?stop == stop sprinkling, close all valves and stop pump
  • http://{netzer-ip}/sprinkler.cgi?setmode=x   == switch Netzer sprinkler into mode x (x is number as described above)
  • http://{netzer-ip}/sprinkler.cgi?getmode  == return Netzer sprinkler mode x (as described above)
  • http://{netzer-ip}/sprinkler.cgi?settimer   == get the number off minutes the system is still sprinkling
  • http://{netzer-ip}/sprinkler.cgi?getvalve=1  == get the actual status (open/close) and sprinkler time out of valve 1
  • http://{netzer-ip}/sprinkler.cgi?setvalve=1&timeout=5  == set the sprinkler time out of valve 1 to 5 minutes
