Read Setpoint from a dummy device [Solved]

[HvdW]

Hi,
I have these data:

Code: Select all

{
	"ActTime" : 1588718227,
	"AstrTwilightEnd" : "23:55",
	"AstrTwilightStart" : "03:04",
	"CivTwilightEnd" : "21:48",
	"CivTwilightStart" : "05:12",
	"DayLength" : "15:16",
	"NautTwilightEnd" : "22:42",
	"NautTwilightStart" : "04:18",
	"ServerTime" : "2020-05-06 00:37:07",
	"SunAtSouth" : "13:30",
	"Sunrise" : "05:52",
	"Sunset" : "21:08",
	"app_version" : "2020.2",
	"result" : 
	[
		{
			"AddjMulti" : 1.0,
			"AddjMulti2" : 1.0,
			"AddjValue" : 0.0,
			"AddjValue2" : 0.0,
			"BatteryLevel" : 255,
			"CustomImage" : 0,
			"Data" : "16.0",
			"Description" : "",
			"Favorite" : 1,
			"HardwareID" : 4,
			"HardwareName" : "Dummy",
			"HardwareType" : "Dummy (Does nothing, use for virtual switches only)",
			"HardwareTypeVal" : 15,
			"HaveTimeout" : false,
			"ID" : "001405F",
			"LastUpdate" : "2020-05-06 00:30:01",
			"Name" : "Thermostaat_setpoint",
			"Notifications" : "false",
			"PlanID" : "0",
			"PlanIDs" : 
			[
				0
			],
			"Protected" : false,
			"SetPoint" : "16.0",
			"ShowNotifications" : true,
			"SignalLevel" : "-",
			"SubType" : "SetPoint",
			"Timers" : "true",
			"Type" : "Thermostat",
			"TypeImg" : "override_mini",
			"Unit" : 1,
			"Used" : 1,
			"XOffset" : "0",
			"YOffset" : "0",
			"idx" : "15"
		}
	],
	"status" : "OK",
	"title" : "Devices"
}

and this script:

Code: Select all

-- assumptions:
-- the setpoint is set by a dummy device (not a selector type) 

local CV_SWITCH = 'CV_switch_auto' -- switch device
local TEMP_SETPOINT = 'Thermostaat_setpoint' -- selector dummy device
local TEMP_SENSOR = 'Oregon'
local LOGGING = true

return 
{
    on = 
    {
        timer = 
        {
            'every minute'
        },
    },

    logging =   
    {
        level = LOGGING and domoticz.LOG_DEBUG or domoticz.LOG_ERROR,
    },

    execute = function(dz)

        local boiler_switch_state = dz.devices(CV_SWITCH).state           
        local temperatuur = dz.devices(TEMP_SENSOR).temperature           
        local temp_gewenst = dz.devices(TEMP_SETPOINT).SetPoint              
        local setpointValue = tonumber(temp_gewenst)                         

        dz.log('CV_SWITCH: ' .. boiler_switch_state, dz.LOG_DEBUG)
        dz.log('Temperatuur: ' .. temperatuur, dz.LOG_DEBUG)
        dz.log('Temperature: ' .. temp_gewenst, dz.LOG_DEBUG)
        dz.log('Setpoint_value (int): ' .. setpointValue, dz.LOG_DEBUG)
    end
}

and this outcome:

Code: Select all

What am I doing wrong?

Hi,
I have these data..,

and this script:..

What am I doing wrong?

dzVents always start variable and attribute names lowercase and case matters.

You use SetPoint; dzVents expect setPoint

Check the wiki for the exact attribute names.
