Window open -> stop heating

[groovesurfer]

Hello,

I use different heating sensors (Eurotronic Spirit) and windows open/closed sensors.
Now I want the heating sensor to lower the temperature to 10 degrees when the window is opened. When the window is closed again, the temperature should return to the previous value.
I tried to do this with the following event:
This works, but the heating sensor continuously readjusts (every 30 seconds) loudly.
Is there any other way to do this?
My heating plan:
0am - 18 degrees
6am - 21 degrees
9pm - 18 gedrees

I would not know how to do this in Blockly (probably something with an additional uservariable)
but in dzVents it could look like below script.

When not yet familiar with dzVents please start with reading Get started Before implementing (~ 5 minutes). Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents enabled' is checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state."

Code: Select all

return
{
    on =
    {
        devices =
        {
            'Türe Terrasse',
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG, -- change to domoticz.LOG_ERROR when all ok
        marker = 'Heizung',
    },

    execute = function(dz, item)

        local heizung = dz.devices('Heizung Wohnzimmer')

        local function setSetPoint(dv, setPoint)
            local function round(value)
                return dz.utils.round(value, 1)
            end
            if round(dv.setPoint) ~= round(setPoint) then
                dv.updateSetPoint(round(setPoint))
            end
        end

        local function thermostat(dv)
            local setPoint = 18
            if dz.time.matchesRule('at 06:00-21:00') then
                setPoint = 21
            end
            setSetPoint(dv, setPoint)
        end

        dz.log(item.name .. ' updated. State is now ' .. item.state,dz.LOG_DEBUG)

        if item.state == 'Open' then
            setSetPoint(heizung, 10)
        else
            thermostat(heizung)
        end
    end
}

Thank you very much for your reply.
The script works, but when I open the door/window (the heating sensor goes to 10 degrees) an close it again, it goes to 18 degrees and not to 21.
What can I do?

Please try again after changing the line

Code: Select all

if dz.time.matchesRule('06:00-21:00') then

to

Code: Select all

if dz.time.matchesRule('at 06:00-21:00') then

[groovesurfer]

Cool, that works. Thank you very much.

Now it´s after 21:00 o´clock and the heating didn´t change the temperature to 18 degrees.
What can be the mistake?

So far the script only reacted to a device event. This one should also control the thermostat time based.

Code: Select all

return
{
    on =
    {
        devices =
        {
            'Türe Terrasse',
        },
        timer =
        {
            'at 06:00',
            'at 21:01',
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG, -- change to domoticz.LOG_ERROR when all ok
        marker = 'Heizung',
    },

    execute = function(dz, item)

        local heizung = dz.devices('Heizung Wohnzimmer')

        local function setSetPoint(dv, setPoint)
            local function round(value)
                return dz.utils.round(value, 1)
            end
            if round(dv.setPoint) ~= round(setPoint) then
                dv.updateSetPoint(round(setPoint))
            end
        end

        local function thermostat(dv)
            local setPoint = 18
            if dz.time.matchesRule('at 06:00-21:00') then
                setPoint = 21
            end
            setSetPoint(dv, setPoint)
        end

        if item.isTimer then 
            thermostat(heizung)
        else
            dz.log(item.name .. ' updated. State is now ' .. item.state,dz.LOG_DEBUG)
            if item.state == 'Open' then
                setSetPoint(heizung, 10)
            else
                thermostat(heizung)
            end
        end
    end
}

I have the same constellation with the Eurotonics and window-sensors. I did it in another way. When window is opended, I change the haeating mode to off, when window is closed, I turn it on again. It switches automatically to the last temperature. The time based temperatures are onyl handled in time-plans of the thermostat device. To switch the heater off or on, I have a dummy-switch. When turning this off or on, the eurotonics changes the mode. The advantage of this is, that I see automatically at this switch, if all works correct when window status changes. All is done with lua.

[groovesurfer]

Thank you for your posts.
@harry: can you tell me it how you have done it with lua? I never used lua before.

[harrykausl]

If you want to do it with lua, you should test a little bit with that environment. Then I can try to help you.

[waaren]

I never used lua before.

Yes you did
dzVents is 100% Lua

[groovesurfer]

ah ok
The script (waaren) works now perfect.
Thank you
