Use an error in log as a trigger

[waaren]

This is not test message. Its a button with not existing URL on action - thats what i want to monitor, if i turn on heating and device (esp8266) is not respondig, revert status of my switch back by call url directly to device in domoticz.. Maybe this is not the correct way, because now is searching for all erros in log.

Do you know any better way how to monitor and revert back if URL of switch is not accessible ?

I do not completely understand all the steps in your procedure but it seems to me that you try to notify dzVents that something happened via the domotiocz-log. Would it not be easier to notify dzVents directly if the device is updated or if that's not feasible, trigger a customEvent using the API from the On action?

Code: Select all

/json.htm?type=command&param=customevent&event=MyEvent&data=MyData

see for a detailed howto [url=https://www.domoticz.com/wiki/DzVents:_ ... _.7D_3.0.0\ the dzVents wiki [/url]

I have few esp8266 devices, which all i am using http commands instead of mqtt because if URL (esp is not running) is not accessible, domoticz write it to log and i know, the button is showing "on" in domoticz but in reality is "off" because it was not able during "switching on" process in domoticz... Now few critical switches like heating or irrigation when i am using out of my house, i always manually checking in domoticz log, if everythink is okay...and that is what i want to automate :-/

[Biiiiino]

For example:

When i switch in domoticz button "heating" to on, it calls url (on action in virtual switch):

http://192.168.1.241/control?cmd=GPIO,12,0

If that URL is not accesible from domoticz (esp8266 is not running) it will mark it to log as "Error opening url: http://http://192.168.1.241/control?cmd=GPIO,12,0

After that i want automaticaaly open another URL directly to switch button in domoticz back:

http://127.0.0.1/json.htm?type=command& ... itchcmd=on


When this happen, i see the real state of the heating unit in domoticz

[waaren]

If that URL is not accesible from domoticz (esp8266 is not running) it will mark it to log as "Error opening url: http://http://192.168.1.241/control?cmd=GPIO,12,0

Below solution seems to be simpler.
Please make sure you remove the "On action" from heating before testing

Code: Select all

local scriptVar = 'myheating'

return 
{
    on = 
    {
        devices = 
        {
            'heating',
        },
        httpResponses = 
        {
            scriptVar,
        }
    },
    logging = 
    {
        level = domoticz.LOG_DEBUG,
        marker = 'scriptVar',
    },
    
    execute = function(dz, item)

        if item.isDevice and item.active then
            dz.openURL(
            {
                url = 'http://192.168.1.241/control?cmd=GPIO,12,0',
                callback = scriptVar
            })
        elseif item.isHTTPResponse and item.ok then
            dz.log('Heating on ESP switched on', dz.LOG_DEBUG)
        elseif item.isHTTPResponse then
            dz.log('There was a problem with the ESP. Switching back the heating switch ', dz.LOG_ERROR)
            dz.log(item, dz.LOG_DEBUG)
            dz.devices('heating').switchOff().silent()
        end

    end
}

Waaren OMG!!! thank you so much, please last think from me. Could you add there also option, when this situation happen if i turn switch off ?

Its possible to have it in one script ? Revert to on ( when url not avalabile) revert to off ( when url not available) ?

again thank you a lot

[waaren]

Please last thing from me. Could you add there also option, when this situation happen if i turn switch off ?

What is the url to switch the heating to Off on the ESP ?

[Biiiiino]

http://192.168.1.241/control?cmd=GPIO,12,1

[waaren]

please last thing from me. Could you add there also option, when this situation happen if i turn switch off ?

Could look like below

Code: Select all

local scriptVar = 'myheating'

return
{
    on =
    {
        devices =
        {
            'heating',
        },
        httpResponses =
        {
            scriptVar,
        }
    },
    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = 'scriptVar',
    },

    execute = function(dz, item)

        if item.isDevice then
            local action = 1
            if item.active then
                action = 0
            end

            dz.openURL(
            {
                url = 'http://192.168.1.241/control?cmd=GPIO,12,' .. action,
                callback = scriptVar,
            })

        elseif item.isHTTPResponse and item.ok then
            dz.log('Heating on ESP switched, dz.LOG_DEBUG)
        elseif item.isHTTPResponse then
            dz.log('There was a problem with the ESP. Switching back the heating switch.', dz.LOG_ERROR)
            dz.log(item, dz.LOG_DEBUG)
            dz.devices('heating').toggleSwitch().silent()
        end

    end
}

Looks great, its possible to split log message based on action?

Eg if “on” cant be switched - log message: heating cant be turned on is stiĺ off

And reverse on off action

Its that possible? Thaank you

[waaren]

Looks great, its possible to split log message based on action?
Its that possible? Thaank you

Yes that's possible. You can retrieve the current state of the device using dz.devices('heating').state and base your log message on that state.
Please try it yourself

[Biiiiino]

Okkay thats totaly out of my skill you can trust me:) but again one more big THANK YOU waaren.

[Biiiiino]

but if you have a bit of free time...

[Biiiiino]

Im trying to do it like this:

Code: Select all

local scriptVar = 'myheating'
local kurenie = 'test_switch'


return
{
    on =

        devices =
        {

        },
        httpResponses =
        {
            scriptVar,
        }
    },
    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = scriptVar,
    },

    execute = function(dz, item)

        if item.isDevice then
            local action = 1
            if item.active then
                action = 0
            end

            dz.openURL(
            {
                url = 'http://192.168.1.800/control?cmd=GPIO,12,' .. action,
                callback = scriptVar,
            })

        elseif item.isHTTPResponse and item.ok then
          dz.log('Heating on ESP switched', dz.LOG_DEBUG)
        elseif item.isHTTPResponse then
            if dz.devices(kurenie).state == Off  then
                dz.log('Cant turn switch ON, stay turned OFF.', dz.LOG_ERROR)
                dz.log(item, dz.LOG_DEBUG)
                dz.devices(kurenie).toggleSwitch().silent()
            
        elseif item.isHTTPResponse then 
            if dz.devices(kurenie).state == On  then

You were quite close. States are strings

Aah okay, thank you one more time.

[Zachtstaart2002]

Found this discusion because i want the same thing. Copied the script and edited to my need. Works as a charme. I have one question. Is it normaal that it logs in the error log of domoticz every time it finds a error message?

this is the script i have running every three minutes.

Code: Select all

-- WLED: No transport, write directive to 'JSONConn' ignored.
myHttpResponse = "getDomoticzErrorLog"

return {
    on      =   {   httpResponses   =   { myHttpResponse },
                    timer           =   { "every 3 minutes"},
                },

    logging =   {   level           =   domoticz.LOG_DEBUG,
                    marker          =   "getStr from log"    },

    data    =   {   lastlogtime     =   { initial = 0 }}, 

    execute = function(dz, trigger)
        
        local searchStr = "WLED: No transport, write directive to 'JSONConn' ignored."          -- Change to reflect the messages you want to catch

        local function askDomoticzForLogLines()
            local lastLogTime = dz.data.lastlogtime            -- get time last logrequest
            local logLevel    = 4                              -- loglevel (1=normal,2=Status,4=error,268435455=all

            local logURL      =  dz.settings["Domoticz url"] .. jsonString
            
            dz.openURL  ({ url      = logURL,
                           method   = "GET", 
                           callback = myHttpResponse 
                        })

            dz.data.lastlogtime = dz.time.dDate        -- store current Time as seconds from epoch  
        end

        local function findString()
           if trigger.json.result ~= nil then               -- Only when there are errormessages in the log
               local resultTable = trigger.json.result
               for i = #resultTable,1,-1 do                 -- traverse backwards to get latest violation first
                    local s = resultTable[i].message
                    local found = s:find(searchStr,1,true) -- searcg plain string starting at pos 1 (no pattern) 
                    local dzVents = s:find("dzVents")
                    if found and not(dzVents) then
                       return true
                    end
                end
            end
        end

        if trigger.isDevice or trigger.isTimer then
            askDomoticzForLogLines()                     -- get the relevant loglines
        elseif trigger.ok then
            dz.log("Show ALL: \n" .. trigger.data,dz.LOG_DEBUG)
            if findString() then
                dz.log("string " .. searchStr .. " found!!!!!!!!!! ",dz.LOG_DEBUG)
                if dz.devices('Vir_Openhaard').state == 'On' then
                    dz.log("Zou Openhaard aan moeten gaan",dz.LOG_DEBUG)
                    dz.devices('Openhaard').switchOff()
                -- else
                    -- dz.devices('Openhaard').switchOn()
                end
                -- dz.notify('Openhaard gereset vanwege WLED foutmelding',dz.PRIORITY_LOW)
                -- dz.notify("searchStr", searchStr, dz.PRIORITY_NORMAL, nil, nil, dz.NSS_PUSHOVER)
            else    
                dz.log("No (new) occurrences of string " .. searchStr .. " in the domoticz log ",dz.LOG_DEBUG)
            end    
        else
            dz.log("Access problem to log. Data found: " .. trigger.data,dz.LOG_ERROR)
       end
    end
}

In the error log of domoticz it looks like this:

Any idea why this appears in the error log? Is it something to wory about?

[mgugu]

I asked chatGpt for such a dzvents script, here its answer:

Code: Select all

return {
	on = {
		log = {
			types = { "error" },
			level = 4
		}
	},
	execute = function(domoticz, item)
		-- Code for action
		domoticz.notify("Error detected in log", "An error has been detected in the Domoticz log. Check the logs for details.", domoticz.PRIORITY_HIGH)
	end
}

Syntax is correct but it is not working because the on log trigger does not exist.
Stange, where does that come from ? Nothing from Google

Change the logging level to LOG_ERROR there:

Code: Select all

    logging =   {   level           =   domoticz.LOG_DEBUG,
                    marker          =   "getStr from log"    },
