Trigger on "Dummy/Usage/Electric" device

[Freemann]

I have a Dummy device which holds the "household power usage", which can be positive or negative (solar panels production) value.

I want to trigger on this device, but I can't get it to work.

Here's the script;

Code: Select all

return {
	active = true,
	on = {devices = {'WebSolarLog - HuisVerbruik'}},
		execute = function(domoticz, device)
			domoticz.notify('Energy trigger!!')
			domoticz.email('Energy trigger!!')
		end
}

'WebSolarLog - HuisVerbruik' is the dummy device.

[Freemann]

Nobody an solution?

[freijn]

This one is in Lua , not perfect (as I am struggeling with the trigger as well )but working.
My problem is that the updates from the solar are much less then the power meter , hence you get weird values now and then.
I still need to work on report after the solars are not generating energy anymore.

Perhaps it helps you getting started ?

Code: Select all

--
-- Domoticz passes information to scripts through a number of global tables
--
-- device changed contains state and svalues for the device that changed.
--   devicechanged['yourdevicename'] = state 
--   devicechanged['svalues'] = svalues string 
--
commandArray = {}

--powersensor = "Power"

--if (devicechanged[powersensor]) then
 --  print( " ####Power debug: "..devicechanged[powersensor])
   -- commandArray['Variable:LUX']=tostring(devicechanged[luxsensor])
--  var1, var2,var3,var4,var5,var6 = string.match(otherdevices_svalues['Power'], "(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*)")
--   print( " ####Power debug: "..var6)
 --  end

solarsensor = "SolarEdge kWh"
if (devicechanged[solarsensor]) then
   --print( " ####Solar debug: "..devicechanged[solarsensor])
   Solarvar1, var2 = string.match(otherdevices_svalues[solarsensor], "(%d+%.*%d*);(%d+%.*%d*)")
   print( " ####Solar debug: "..Solarvar1)

   powersensor = "Power"
   -- if (devicechanged[powersensor]) then
   --print( " ####Power debug: "..devicechanged[powersensor])
   var1, var2,var3,var4,Powervar5,Powervar6 = string.match(otherdevices_svalues['Power'], "(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*);(%d+%.*%d*)")
   print( " ####Power debug: "..Powervar5)

   powercount = tonumber(Powervar6)
   solarcount = tonumber(Solarvar1)
 
   consume = solarcount - powercount
   print( " ####Consume debug: "..consume)
 
   ttidx = otherdevices_idx['PowerConsumtion']
   commandArray['UpdateDevice'] = ttidx..'|0|'..consume
end

return commandArray

Thanks for your script and code!
I also have a very extensive LUA scripts to do certain stuff based on my Solar production.
I'm moving some native LUA scripts to dzVents and now I'm struggling to get the script triggered on the Dummy Energy device.

So for now my native LUA is running OK, but I can't get it to work in dzVents.
Really want to get this to work, because dzVents is an awesome extension and save me a lot of coding

[dannybloe]

Ok, there are a couple of things you can try. First of all, you can put dzVents in debug logging mode (Domoticz settings). Then see in the log if you can see if there is an event triggered if your device was changed. dzVents should log this even though it may not call your script. Also, maybe trivial, make sure the script is active if you created it using the web editor to create the script. I tend to forget this occasionally myself.
If that is all the case, try to use the id/idx instead of the device name to create the on-trigger and see if that works.

[Freemann]

Logging isn't showing an trigger (debug is at highest level), also the notify and email are not received.

Will try the IDX option and report back.

[Freemann]

script is now, with IDX in place, looking like this;

Code: Select all

return {
	active = true,
	on = {devices = {82153}},
		execute = function(domoticz, device)
			domoticz.email('Energy trigger!!')
			domoticz.notify('Energy trigger!!')
		end
}

No notifications and/or email and here's the logscreen and device with its last trigger time;

(the red oval should be one device lower)

[dannybloe]

Is that the id of the device??? Check the idx column of the device list in domoticz. Never seen such a high number.

Hi,

some time ago I had a problem with virtual Temperature device - LUA (nor dzVents ?) not triggered on device change. I solved it differently, but now i tested it again - looks it still not works (on beta 3.8312 currently). Maybe other dummy/virtuals types have same problem.

Simple script:

Code: Select all

return {
        active = true,
        on = {
                devices = {
                'esp Temp' -- virtual Temperature device
                }
        },
        execute = function(domoticz, esp)
                domoticz.log('esp Temp changed')
        end
}

Then update via JSON call:

Code: Select all

192.168.1.23:8080/json.htm?type=command&param=udevice&idx=126&nvalue=0&svalue=21

Script not triggered. Interesting part - simple Blockly event works OK

Is it bug or feature ? (I think it's in Domoticz event system, not dzVents)

And you are sure that the script is active in the internal editor and dzVents is enabled? Does it log anything when dzVents is set to debug logging after you call the json?

[mivo]

Aah, sorry Danny, I had dzVents logging set to Errors + forced - too early morning . Works now via JSON call for dummy Temperature and dummy Usage/Electric too.

I just looked to my old scripts, where I tested behaviour of not triggering Dummy Temp device. It worked via JSON call, but not by domoticz.devices('some dev').updateTemperature(). Tested now again and I can confirm it.

@Freemann, how do you update dummy Usage/Electric device, which does not trigger script ? JSON, or LUA/dzVents method ?

[Freemann]

Tried to duplicate the dzVents script to Blocky and it looks like Blocky is also not triggering on the changes of the Dummy device.

I update the dummy devices through LUA and here's and short snippet;

Code: Select all

dIDX = getDeviceIDX('WebSolarLog - ZonneStroom')
commandArray[1] = {['UpdateDevice'] = dIDX .. '|0|' .. data.totals.production.GPOverall}

dIDX = getDeviceIDX('WebSolarLog - HuisVerbruik')
commandArray[2] = {['UpdateDevice'] = dIDX .. '|0|' .. data.totals.metering.liveEnergy}

dIDX = getDeviceIDX('WebSolarLog - StroomBeschikbaar')
commandArray[3] = {['UpdateDevice'] = dIDX .. '|0|' .. powerAvailable}

I'm now a bit lost on this subject.

[dannybloe]

Ok, back to the start.. you have a device 'WebSolarLog - HuisVerbruik' and you want it to be triggered by dzVents but that doesn't happen somehow.
In my dzVents development branch I have added a troubleshooting section to the documentation. This is not in the wiki yet but perhaps you can read it and see if that helps you (most of the stuff in the troubleshooting section should still work in the current released version):

Nice Wiki!

Is dzVents enabled?
Yes

Is your script enabled?
Yes

Turn on debug logging;

So, every time Domoticz starts dzVents ánd debug logging is enabled you should see these lines:
dzVents version: x.y.z

Script is still not execued?
If for some reason you script is not executed while all of the above is done, it is possible that your triggers are not correct.
There's no timerule and the ID's are (now) correct (153)

Also, make sure that your device names are unique!
Name is unique

If your script is still not triggered, you can try to create a classic Lua event script and see if that does work.
Tried to make a classic LUA and that's also not working (already posted that)

Debugging your script
The script is very straight forward.... what should i debug?

This confuses me. In your Domoticz version you should see something like this every time dzVents starts processing: Event trigger type: ... I don't see that here. And... Warmtepomp? I was expecting to see 'WebSolarLog - HuisVerbruik'.

What did you do exactly to trigger this event (if it would work)?

[Freemann]

This was just a random set of lines, because I don't see the 'WebSolarLog - HuisVerbruik' coming by.
This is the current script;

Code: Select all

return {
	active = true,
	on = {devices = {153,'153','WebSolarLog - HuisVerbruik'}},
		execute = function(domoticz, device)
			domoticz.email('Energy trigger!!')
			domoticz.notify('Energy trigger!!')
		end
}

Ok, but I'm more interesting in what you do that should cause the 'WebSolarLog - HuisVerbruik' script to be executed.

Hi,

JSON / openUrl update method of dummy device triggers script correctly:

This script updates dummy device based on switch states (just example):
test_switch.lua

Code: Select all

return {
    active = true,
    logging = {
        level = domoticz.LOG_INFO,
    },
    on = {
        -- trigger on device with name
        devices = {'switch'}
    },

    execute = function(domoticz, device)
        -- check state of device
        if device.state == 'On' then
                -- log for debugging purpose
                domoticz.log('switch is ON')
                -- JSON call
                local updDevice = domoticz.devices('test temp') -- device to update
                local newValue = '21' -- new value
                url = domoticz.settings['Domoticz url'] ..
                        '/json.htm?type=command&param=udevice&idx=' .. updDevice.idx  .. '&nvalue=0&svalue=' .. newValue

                domoticz.openURL(url)

        elseif device.state == 'Off' then

                domoticz.log('switch is OFF')
                -- JSON call
                local updDevice = domoticz.devices('test temp') -- device to update
                local newValue = '23' -- new value

Yes, I see this.. we are exploring this and see if we can fix this. Thing is that perhaps people in some situation don't expect the event system to be triggered when sending in UpdateDevice command.

[Freemann]

What do you need from me to help debug this further?
