Send notification after switch been off for 2h

[Ivanhoe1]

Hi,
Cant figure out how to do what seems be a easy thing. I have an Nexa transmitter that sends on/off to domiticz when my robotic lawnmover leaves and return for charging. I want domoticz to send me an notification when the robot been away for 2 hours. How could I do this? In other word, when therese been Off recieved from the switch for mote then 2h i will get the notification.

Hi,
Cant figure out how to do what seems be a easy thing. I have an Nexa transmitter that sends on/off to domoticz when my robotic lawnmower leaves and return for charging. I want domoticz to send me an notification when the robot been away for 2 hours. How could I do this? In other words, when there has been no Off received from the switch for more then 2 hours i will get the notification.

Unfortunately there is no native domoticz timer to help here. The script below uses the afterNNN method of dzVents to emulate this.

When not yet familiar with dzVents please start with reading Get started Before implementing. Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents disabled' is not 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

scriptVar = "yourSwitchDelay" 
lawnmowerSwitch = "lawnmowerActive"

return {
    on  = {     devices = { lawnmowerSwitch }, -- change to 'name' or ID of your lawnMower active switch
                httpResponses   =  { scriptVar}},
                
    logging =   {   level     =   domoticz.LOG_DEBUG,           
                    marker    =   scriptVar    },
                
    execute = function(dz, item)
        local  delay  =  7200               -- delay in seconds Adjust to your needs
        local  jsonString   = dz.settings['Domoticz url'] .. "/json.htm?type=command&param=addlogmessage&message=Waiting%20is%20over"

        if item.isHTTPResponse then
            if dz.devices(lawnmowerSwitch).active and lawnmowerSwitch.lastUpdate.secondsAgo > ( delay - 100 ) then
                dz.notify('Lawnmower','Lawnmower away for '.. lawnmowerSwitch.lastUpdate.secondsAgo ..' seconds',dz.PRIORITY_NORMAL)
            end
        elseif item.active then -- lawnmowerSwitch switched to On
           dz.openURL  ({ url      = jsonString,  
                          method   = "GET", 
                          callback =  scriptVar }).afterSec(delay)             -- to come back after delay seconds 
        end                                      
    end
}

Tried the script but ran in to a problem with "attempt to index field 'lastUpdate' (a nil value) ". Log below.
Should the uservarible be an integer?

No I made a couple of mistakes in copy / pasting the script to the forum. Probably a bit too late or too much wine at that time of night and some confusion about the devicename lawnmower vs lawnmover. I now followed you and used the string 'lawnmover'
Can you please try again with this ?

Code: Select all

scriptVar = "yourSwitchDelay" 
lawnmoverSwitch = "lawnmoverActive"

return {
    on  = {     devices = { lawnmoverSwitch }, -- change to 'name' or ID of your lawnMower active switch
                httpResponses   =  { scriptVar}},
                
    logging =   {   level     =   domoticz.LOG_DEBUG,           
                    marker    =   scriptVar    },
                
    execute = function(dz, item)
        local  delay  =  7200               -- delay in seconds Adjust to your needs
        local  jsonString   = dz.settings['Domoticz url'] .. "/json.htm?type=command&param=addlogmessage&message=Waiting%20is%20over"

        if item.isHTTPResponse then
            mySwitch = dz.devices(lawnmoverSwitch)
            if mySwitch.active and mySwitch.lastUpdate.secondsAgo > ( delay - 100 ) then
                dz.notify('Lawnmover','Lawnmover away for '.. mySwitch.lastUpdate.secondsAgo ..' seconds',dz.PRIORITY_NORMAL)
            end
        elseif item.active then -- lawnmoverSwitch switched to On
           dz.openURL  ({ url      = jsonString,  
                          method   = "GET", 
                          callback =  scriptVar }).afterSec(delay)             -- to come back after delay seconds 
        end                                      
    end
}

Works like a charm! Thanks!
Now you deserve another bottle of wine.
