Fish pond pump script

[D3LTA]

Anyone here knows if there is a Fish pond pump script that deals with time and weather data?

i searched everywhere and also tried making my own from some heating scripts but without any luck and working script....

what i'm looking for is a script that sets on the pond pump x time (for example 2 hours and then off) at a x interval (example 2 hours on and 1 hours off and repeats that )

and if the temperature is below a x variable (like 0 degrees) it will not turn in on at all of turns is on continuously

i truly hope some of you could help me out or can give me some examples to work with.

(made serveral bash and python scripts, but i can't seem too figure out this one)

thanks alot

In Lua, just give youre some idea;s to get you started with the timing :

Code: Select all

time = os.date("*t")

put the time/date table in variable time

Code: Select all

 if (time.hour==7 or time.hour==19) and time.min==0 then ....pump on or off  ..... end

time.hour contains the hours of time.
time.min contains the minite of time

Code: Select all

if ((time.min% 2)==0) then ..... end

would run every 2 minutes, this can also be done with time.hour.

Dont forget to load the table in time (first sentence)

thanks for the push in right direction.. will give it a shot tonight.. is it okay if i post my progress here.. so you can maybe help me out a little?

See PM and yes you can post it here if you made something, that way others can benefit or think together with you

With pass2php times are quite easy:

Code: Select all

<?php
$temp=status('temperature');
$pump=status('pump');
if($temp>25){
	//To hot, let's pump continuosly
	if($pump!='On')sw('pump','On');
}elseif($temp>0){
	//Normal temp
	if($pump=='On'&&timestamp('pump')<time-7200)sw('pump','Off');
	elseif($pump=='Off'&&timestamp('pump')<time-3600)sw('pump','On');
}else{
	//It's freezing cold, don't pump at all
	if($pump!='Off')sw('pump','Off');
}

$pump=status('pump');

}elseif($temp>0){

}else{

	if($pump!='Off')sw('pump','Off');
}

that looks very good indeed, but how does it get the var temp and pump? are those the names in domoticz ?

i can read the script and understand it.. but can you explain the "timestamp".. is that a persistant value? or does it read the time variables from domoticz? ("last seen")

How do i implement it?

[Egregius]

Yes, the names of Domoticz.
You'll need to get pass2php running. All the magic happens there.

[D3LTA]

thats no problem, please help me understand the script (timestamps) as i have no php knowledge.

is it also possible to store values? because for example if it freezes for 2 days, and temp gets above 0 again.. it takes for example 5 days before the pump can start again because the ice needs to melddown.

[D3LTA]

realy hope you or someone willing to make this a working script... i just don't have the knowledge..yet..

[Egregius]

you can store custom variables with the setstatus() function and read them with the status() function of pass2php.
You could (for example) set a variable 'hasfrozen' to the lowest frost temperature. pass2php automatically remembers the last set time of a var.

Didn't test this, but something like this could be a good direction:

Code: Select all

<?php
$temp=status('temperature');
$pump=status('pump');
if($temp>25){
	//To hot, let's pump continuosly
	if($pump!='On')sw('pump','On');
}elseif($temp>8){
	//Normal temp, let's cycle 2 hours on, 1 hour off	
	if($pump=='On'&&timestamp('pump')<time-7200)sw('pump','Off');
	elseif($pump=='Off'&&timestamp('pump')<time-3600)sw('pump','On');
}elseif($temp>0){
	//It's cold, did it freeze lately?
	$hasfrozen=status('hasfrozen');
	$hasfrozentime=timestamp('hasfrozen');
	if($hasfrozen<-20){
		//damned that was cold, lets wait 10 days
		if($hasfrozentime<time-(86400*10)){
			if($pump=='On'&&timestamp('pump')<time-7200)sw('pump','Off');
			elseif($pump=='Off'&&timestamp('pump')<time-3600)sw('pump','On');
		}
	}elseif($hasfrozen<-10){
		//damned that was cold, lets wait 5 days
		if($hasfrozentime<time-(86400*5)){
			if($pump=='On'&&timestamp('pump')<time-7200)sw('pump','Off');
			elseif($pump=='Off'&&timestamp('pump')<time-3600)sw('pump','On');
		}
	}elseif($hasfrozen<-5){
		//damned that was cold, lets wait 2 days
		if($hasfrozentime<time-(86400*2)){
			if($pump=='On'&&timestamp('pump')<time-7200)sw('pump','Off');
			elseif($pump=='Off'&&timestamp('pump')<time-3600)sw('pump','On');
		}
	}elseif($hasfrozen<0){
		//Just a litle frost, one day will do
		if($hasfrozentime<time-86400){
			if($pump=='On'&&timestamp('pump')<time-7200)sw('pump','Off');
			elseif($pump=='Off'&&timestamp('pump')<time-3600)sw('pump','On');
		}
	}else{
		//It didn't freeze, lets cycle
		if($pump=='On'&&timestamp('pump')<time-7200)sw('pump','Off');
		elseif($pump=='Off'&&timestamp('pump')<time-3600)sw('pump','On');
	}
}else{
	//It's freezing cold, don't pump at all
	if($pump!='Off')sw('pump','Off');
	$hasfrozen=status('hasfrozen');
	if($temp<$hasfrozen)setstatus('hasfrozen',$temp);
}

Thank you very much Egregius.. will give it a try

what will happen if it's -11 2 days in a row? it will just stay 5 days with every extra day its still freezing -11 ?

Anyone willing to help debug and improve this script?

thanks in advance
