Hello,

it seems that I have run into a brick wall and I am in need of an extra set of eyes (more experianced!)

I am building a script for my wellpump and 3 zones that are switched via a z-wave powersocket
I want the pump to automatically start when I enable one of the zone switches for 60minutes -1 and the zone for 60minutes.
if I switch on 2 zones and switch off one zone, then the pump must continue as there is still a zone who is "asking" for water.

I have used user variables in domoticz voor_aan, achter_aan and druppelslang_aan.
what I see happening is that the pump will start how it is requested, but it will not disable.
I see that the user var seems to be changed after the script calls for the enable/disable pump function and thus sees still one zone as 'true'

is there a way how I make sure the order is done correctly and (for me) as expected? or am I missing something?

return {
	on = {
		devices = {
			'Waterpomp',
			'Sproeier Voor',
			'Sproeier Achter',
			'Druppelslang'

What I see is that you set the uservariables to 'false' and in the same execution of the script check if the value is 'false'
This does not work in eventscripts because the actual change of the var (and also the switch of a device) will only happen after the script finished. The commands are send back to domoticz and the domoticz main process will perform the actions.
If you want variables to be interpreted during the same execution of the script and also in other runs of the same script you need to change them to dzVents persistent variables.

Thanks, I was not aware of that fact, I just read up on the persistent vars and I will change it and check if it works!

hmm, I guess I am in need of some more advice, I guess I am using the persistent variable wrong, can some one please have a look. if I execute one of the zones, i get this message: Error: dzVents: Error: (3.0.4) .../domoticz/scripts/dzVents/generated_scripts/pomp_lua.lua:57: attempt to index a nil value (field 'data') I am also not sure if I can use actual booleans here, so I reverted to string checking.

You misplaced one }
dzvents now sees data as part of the on = section
the data can be boolean.

Should look like

Code: Select all

return 
{
    on = 
    {
        devices = 
        {
            'Waterpomp',
            'Sproeier Voor',
            'Sproeier Achter',
            'Druppelslang'
        },
    },
    
    data = 
    {
            voor_aan    = { initial = 'false' },
            achter_aan  = { initial = 'false' },
            druppel_aan = { initial = 'false' },
    },        
    
    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = 'Waterpomp',
    },

lol that makes sense, thanks!
its good to make mistakes, now I learned what to look for in my other scripts, as I am converting my blockly to dzvents.
