dzvents after update to version 4.97

Posted: Wednesday 22 August 2018 15:27

Domoticz ver 4.97 on Raspberrypi

The dzvents-script below (ventilator-switch based on a humidity-sensor) worked fine under domoticz-version 3.87. After an update to version 4,97 this script and some others (also based on humidity) do not work anymore. In domoticz version 4.97 the versionnumber of dzvents is not visible anymore.
Th script has a test-mode, but also the test-mode does not work anymore! :cry:
Probably something small, but i cannot find the solution.

Can anybody help?

Thanks

Paul

Does setup->about not show the dz_Vents version? It does on my installation.

Th script has a test-mode, but also the test-mode does not work anymore! :cry:
Are you sure this script worked in other versions ?
Do you see anything in the log ?

The two lines below will give errors

Code: Select all

   local   Vent = domoticz.devices('VentSchakelaarSL1-')                         -   ??? This single - will cause  unexpected symbol error
    Temp = domoticz.devices('').temperature                               ???? This empty string will cause a problem with the device-adapter

I found the versionnumber: dzvents 2.4.6 and
Indeed between the ' ' a sensor was mentioned so no errors occured (Temp = domoticz.devices('Zolder TH_ch2').temperature)
The single - in Local, Vent = domoticz.devices('VentSchakelaarSL1-') did not give any problem and
I am sure the script worked!

Could it be a cache problem? How to flush cache(s) in Domoticz?

I was not referring to the - between the quotes but to a single - probably left behind after removing a comment on the same line. Lua will not accept such a single - in the middle of your script and therefore dzVents cannot continue with the execution of this script.
Cache can only be a problem in the gui not with execution of any script.
What is in the log ?

I found out that the script works again if I remove the 'test'-part of the script:

=== removed

if (tonumber(uservariables[TEST_MODE_HUMVAR]) > 0) then
current = tonumber(uservariables[TEST_MODE_HUMVAR])
if PRINT_MODE == true then
print('Current Humidity Test Mode: ' .. current)
end
else
current = domoticz.devices('Zolder TH_ch2').humidity
if PRINT_MODE == true then
print('Current Humidity: ' ..SENSOR_NAME .. current)
end
end
=======
For some reason the user-variable "TEST_MODE_HUMVAR' (type variable = integer) causes the trouble.
A nil value error.
Any suggestion?

Thanks
Paul

Change uservariables to domoticz.uservariables

I changed the uservariable.
The error (nil-value) is solved, but as long as the test-mode part is within the script, the script stops further execution. So all log-message before the test-mode part are visible, after the test-mode part the script seems dead.
Remove the test-mode part and the scripts works fine.

So what is de diffrence for this part of the script under this dzvents(2.4.6) in comparision with the version before the update?

thanks for your help.

Paul

Don't know of any relevant differences but if you look at logfile you will see where the script fail.
the dzVents syntax to get the value of a domoticz uservar is domoticz.variables("name of uservar").value

maybe my simplified ventilator activation script can help you.

Code: Select all

 -- Bathroom humidity.lua
 
return {
    on = { timer = { 'every minute' }},
    
    data = { humidityBefore = { history = true, maxItems = 10 }},

--    logging =   {   level   =   domoticz.LOG_DEBUG,
--                    marker  =   "Bathroom humidity" },    

    execute = function(dz)
        local humidity          = dz.devices("Badkamer (Zwave)").humidity
        local vent              = dz.devices('Centrale afzuiging')
        if dz.data.humidityBefore.getOldest() == nil then
          dz.data.humidityBefore.add(99)
        end  
        local humidityBefore    = dz.data.humidityBefore.getOldest().data 		-- value from 10 minutes ago
        
        if humidity == nil or humidity == 0 then
            dz.log("current is 0 or nil. Skipping this reading",dz.LOG_ERROR)            
            return
        end
        
        dz.log(humidity  .. "  HumidityBefore: " .. humidityBefore,dz.LOG_DEBUG)    
                
        if  humidity ~= humidityBefore  then
            if humidity > 65 and humidity > ( humidityBefore + 3)  and vent.state == 'Off' then
                dz.log("Fan off ==>> Switching fan on for 20 minutes",dz.LOG_FORCE)
                vent.switchOn().repeatAfterSec(10,2) -- Repeat command 2 times (after 10 and 20 seconds)
                vent.switchOff().afterMin(20).repeatAfterSec(10,2)                    
            end
        end
        dz.data.humidityBefore.add(humidity)

Oke,

I will try your script, but it does not solve the “test-part” problem in the script with the user-variable that didn’t exits before!

Re: dzvents after update to version 4.97

Accessing a user variable in dzVents is done like this:

Code: Select all

domoticz.variables('myUserVar').value
No need to convert it so number if the variable is defined as such in the GUI.

I understand “ no need to convert it”( the tonumber(xx)) , but i do not understand te rest of your sentence.....

Re: dzvents after update to version 4.97  [SOLVED]

Posted: Tuesday 28 August 2018 17:52
by dannybloe
The type of the variable is defined in domoticz when you created the uservariable. So if it is a number or integer type it will be the same in dzVents.
