dzVents script for heating control [SOLVED]

[alarm_guy1]

Cheers

[renerene]

Does the scrtipt calculate the heating start point in order to reach the setpoint as soon as the required time zone starts?
Or is it just working during the selected time zone?

in other words: Does this script 'think ahead'?

It does not think ahead. Depending on the time zone set and setpoint it tries to keep the temperature in the hysteresis range.

Code: Select all

      -- switching the boiler on or off if the set temperature has been reached
        local temp_to_compare = domoticz.devices(devHEAT).state 
		local switchOnTemp = temp_set - HISTERESIS
		local switchOffTemp = temp_set + HISTERESIS

What is happen (with mode switched) if i just click on "Fire icon" on "Workin mode" device?

[uzturre]

hello:
thank you very much for this good script, with all my respect towards the author, I have translated it into my usual language.
But the object of this message is the error that appears to me and that I have highlighted it in red.
What can be the cause?

Script from line 38 start like this.

Code: Select all

 --=======================================================
        -- USER VARIABLES   // name of user variables in Domoticz ( Setup > More options > User variables). 
 --=======================================================
	local usrStateWorkHEAT     = 'HeatWorkCondition'           -- helper variable to work script 
	local usrLastStatement      = 'HeatStatement'                 -- helper variable last statemen 

"HeatWorkCondition" is the name of the variable you must manually create in "Domoticz". As You see above is also second variable "HeatStatement" which of course You also have to create.

Of course You can change name of variable according to your own needs in this line of script and domoticz's "user variables".

By the way, a slightly newer version of the Polish-language objects names.

"HeatWorkCondition" is the name of the variable you must manually create in "Domoticz". As You see above is also second variable "HeatStatement" which of course You also have to create.

Of course You can change name of variable according to your own needs in this line of script and domoticz's "user variables".

I tell you my installation, I have two pi zero w, one pi zero for the temperature probe installed in the room and the other pi zero with the relay modules next to the boiler, in this pi zero I have a module with 2 relays (relay 1 and relay 3) when the relay 1 is activated its contact closes to give way to the current and activate the relay 3. The relay 3 is subject to the start of the relay 1. This I did because it used blockly and in this way I could do the boiler operated at certain times activating relay 1 (relay 1 with time condition) and this way activate relay 3 which in turn had to meet the temperature condition of the room probe.

As you see in your script, I have changed line 12 and it works for me that way, but only relay 1 remains OFF, relay 3 always remains activated, I do not know how to do it in the correct way.
If you read line 13, if I put it in active mode, the script does not work.

Thank you.

This script cant be used with 2 relays. A lot of line used syntex like egz. " domoticz.devices(devHEAT).switchOff()"
so

Code: Select all

local devHEAT = 'RELE -3-' and 'RELE -1-'     -- switch that will be turned OFF and ON 

is not correct.

If you want still use this script and you have 2 relays, you can use it with one relay and in another script "dzVents" or even blockly do action depending on the condition second and link the actions of these relays.

Thank you very much, the problem is that I do not know how to write code...

Thank you very much, the problem is that I do not know how to write code...

So You can do this in blockly, but i recomnends write script in dzVents. It not very hard to learn and in future you will have more posibilities. Is very good documentation on wiki with a lot of egzamples. See https://www.domoticz.com/wiki/DzVents:_ ... _scripting

Hello, I am using this script for regulating de heating in our house, but unfortunately the ' Holiday' function does not work.
We are on holiday now and I noticed that de heating was still working.
At for now I lowered the ' Comfort temperature' to holiday-level, so the heating is ok, but I would like to make the script work also when we are on holiday.

Any suggestions to solve this?

Does "name" in line nr 25 is the same as SetPoint ?.

Code: Select all

 local devSetpoint_holidays = 'Temperature HOLIDAYS'           -- setpoint: eco temperature for holidays mode

You can debug log from script (of course you have to turn on it in line nr 7)

Code: Select all

 local LOGGING =  true                   -- true or false LOGGING info to domoticz log. 

[corthebor]

Problem solved: Edited the selector switch ' Working mode' . Changed HOLIDAY into HOLIDAYS. And now it's working.
thanks a lot, Very nice and useful script.

These are just messages from the script but send with a loglevel that is recognized by domoticz as an Error. You can change that by changing the lines which are producing these messages and remove the last ,true.

As example change line:

Code: Select all

log(domoticz,' > 24. Target temperature reached, Status => off',true)

to

Code: Select all

log(domoticz,' > 24. Target temperature reached, Status => off')
