Checking a sensor every few seconds

[paul402]

I want to check my fridge door using rxfcom and a door switch. The door switches normally work fine but if the fridge door is closed quickly then the closed signal is missed.
So I looked at this thread for inspiration. viewtopic.php?t=36400
Thanks for that.

My mods look like this.

Code: Select all

local scriptVar = 'every10Seconds'

return
{
    on =
    {
        timer =
        {
            'every minute',
        },
        customEvents =
        {
            scriptVar,
        },
    },

    logging =
    {
        level = domoticz.LOG_ERROR,
        marker = scriptVar,
    },

    execute = function( dz, item )

        if dz.devices('Fridge Door_D3').state == 'Off' then return end -- If fridge door check device state is Off the script will not do anything,

        if item.isTimer then
            for delay = 10, 50, 10 do
                dz.emitEvent(scriptVar).afterSec(delay)
            end
        end

        local fridgedoor = dz.devices('Fridge Door_D3')
        

        local function setvar(var, to)
            if var.value ~= to and dz.startTime.secondsAgo > 60 then var.set(to) end
        end

        if fridgedoor.lastUpdate.secondsAgo > 60 then
            domoticz.log('Fridge Door switch >x seconds')
            msg="Fridge Door Open " .. fridgedoor.lastUpdate.minutesAgo .. " mins/seconds"  
                        domoticz.openURL('https://api.telegram.org/botxxxxxxxxxxxxxxxxxxxxxxxx/sendMessage?chat_id=xxxxxxx&text=' .. msg)   
        else
            domoticz.log('Fridge Door closed')
        end
    end
}

and I'm getting these error messages.
2022-11-14 22:16:00.650 Error: dzVents: Error: (3.1.8) every10Seconds: An error occurred when calling event handler Script #1try-fridge-door
2022-11-14 22:16:00.650 Error: dzVents: Error: (3.1.8) every10Seconds: ...s/dzVents/generated_scripts/Script #1try-fridge-door.lua:42: attempt to index a nil value (global 'domoticz')

It's late, I'm tired, yes and I've had a few glasses of wine too. Please can anyone tell me what I'm missing here.

Replace 'domoticz' in your script (after execute) to 'dz' (without quotes)

Additionally, you should add 'local' in front of 'msg'
I've changed it for you:

Code: Select all

local scriptVar = 'every10Seconds'

return
{
    on =
    {
        timer =
        {
            'every minute',
        },
        customEvents =
        {
            scriptVar,
        },
    },

    logging =
    {
        level = domoticz.LOG_ERROR,
        marker = scriptVar,
    },

    execute = function( dz, item )

        if dz.devices('Fridge Door_D3').state == 'Off' then return end -- If fridge door check device state is Off the script will not do anything,

        if item.isTimer then
            for delay = 10, 50, 10 do
                dz.emitEvent(scriptVar).afterSec(delay)
            end
        end

        local fridgedoor = dz.devices('Fridge Door_D3')
        

        local function setvar(var, to)
            if var.value ~= to and dz.startTime.secondsAgo > 60 then var.set(to) end
        end

        if fridgedoor.lastUpdate.secondsAgo > 60 then
            dz.log('Fridge Door switch >x seconds')
            local msg = "Fridge Door Open " .. fridgedoor.lastUpdate.minutesAgo .. " mins/seconds"  
            dz.openURL('https://api.telegram.org/botxxxxxxxxxxxxxxxxxxxxxxxx/sendMessage?chat_id=xxxxxxx&text=' .. msg)   
        else
            dz.log('Fridge Door closed')
        end
    end
}

Wow! Thanks so much for your help. It works perfectly, of course.
