Dzvents as sprinkler controler

hello,
i would like to control my sprinkler system (4 valves visible as switches in domoticz)
what would be best approach to create dummy switch controlled with dzvents
i want to run (on switch)
1 valve (x min on then switch off)
2 valve (x min on then switch off)
3 valve (x min on then switch off)
4 valve (x min on then switch off)
it even possible to run script for so long?
problem is that i want to be able switch off at anytime and interrupt program and disable valves anytime....?

@devros,
I am not sure I completely understand you requirements but this might be a start.
Create a virtual selector switch with level 0 = Off and other levels are the names of your Valve switches.
If you choose a valve it will be switched to On for 30 seconds by the script or until you manually switch it to Off
- Spoiler: show
Code: Select all
--[[ Sprinkler.lua
]]--
return {
on = { devices = { "Sprinkler" } },
logging = { level = domoticz.LOG_DEBUG,
marker = "Sprinkler"},
execute = function(dz, trigger)
local choice = trigger.levelName
local myValves = {"Valve 1", "Valve 2","Valve 3","Valve 4"}
if choice == "Off" then
for k,v in ipairs(myValves) do
dz.devices(v).switchOff().checkFirst()
end
else
dz.devices(choice).switchOn().forSec(30)
trigger.switchOff().silent()
end
end
}

Wow thanks so simple
this should be as example how dzvents is powerful
thats even better then i wanted...
now only figure out how to add another choice to switch, to run all 4 valves consecutive
and maybe create dummy text variable with time (for easy change)

Add another level to selector with name "All" and add requested time in the description field in seconds like
SprinklerTime: 40
or modify the script a little bit to get different times per valve; you got the idea

logging = { level = domoticz.LOG_DEBUG,

execute = function(dz, trigger)
local choice = trigger.levelName
local sprinklerTime
local description = trigger.description
if description ~= nil and description ~= "" then
_, _, sprinklerTime = string.find(description,"SprinklerTime: (%d+)")
end
sprinklerTime = sprinklerTime or 30
local myValves = {"Valve 1", "Valve 2","Valve 3","Valve 4"}
if choice == "All" then
for k,v in ipairs(myValves) do
dz.devices(v).switchOn().forSec(sprinklerTime)
end
elseif choice == "Off" then
for k,v in ipairs(myValves) do
dz.devices(v).switchOff().checkFirst()
end
else
dz.devices(choice).switchOn().forSec(sprinklerTime)
end
trigger.switchOff().silent()
end
}

great
last question how to handle stop when i run 4 valves consecutive switch
my idea is add next switch selector with stop and use cancelQueuedCommands() function and then disable all valves, or is more elegant way how to interrupt for loop?

Just press the Off selection button; the script will react to that even if the Off was already selected

ooh thanks, will have to study your code

FWIW, I implemented a sprinkler controller with Dzvents, and I'm pleased with it.
I use ESP's running ESPEasy to actually control the relays which turn on the sprinkler valves. I have a front and back, so I have two ESP's (Wemos D1 mini's) to handle this.
Dzvents is used to send the commands to turn on and off the sprinklers.

Yes im also using esp easy - used rflink relay, but esp easy is better

all works great
BTW nice trick with description value
edit: one thing in program (all) are trigered all switches in same time (i want to triger them one after the other)
somehow to modify for loop, dam time to start study Lua
tried this but thats not working
Code: Select all
for k,v in ipairs(myValves) do
dz.devices(v).switchOn().forSec(sprinklerTime).switchOff().afterSec(sprinklerTime)
end

can you try (not tested)
Code: Select all
local delay = 1
for k,v in ipairs(myValves) do
dz.devices(v).switchOn().afterSec(delay).forSec(sprinklerTime)
delay = delay + 1
end
