problems with Persistent data [SOLVED]

[gus]

Hi,

I'm trying to work with Persistent data, but for some reason I don't get it to work the way that I want to.
Even if barometer_old contains the same value (980) as presented in barometer the if state triggers.

This is my code, please advice a LUA dummies...

Code: Select all

              
        data = {
        barometer_old = {},
    },


		if (barometer) ~= (barometer_old) then
			domoticz.devices['Trigger request Text 2_1'].switchOn()
			domoticz.data.barometer_old = (barometer)
		end

Are you sure both values are the same?
I know that for example a setpoint sometimes returns 1 decimal place, and sometimes 2. Like 21.0 and 21.00.
If you then compare that as a string they are different.
I also think you should post the complete code...

Ok, some complements!


This is th values from my log:

Code: Select all

2017-01-11 17:12:00.942 LUA: barometer_old value: 976
2017-01-11 17:12:00.943 LUA: barometer value: 976

This is my code:

I don't know if it is compulsary, but I always give an initial value, even if It is nil.
That is how is described on the dzvents github page

That was included in my first code, but when it didn't work, I'll tried to take it away.

In that case I wouldn't know.

This is a working script I use that is similar to what you want, maybe you find something that can help you

Code: Select all

return {
	active = true,
	on = {
		['timer'] = 'every 30 minutes'
	},
	    data = {
        prevtbath = {initial=15}
		},
		
	execute = function(domoticz)

		local tempd   = domoticz.devices['Temp_bathroom']		
		local prevt = domoticz.data.prevtbath
		local diffd = domoticz.devices['bathdiff']	 
		local precurrtemp = tempd.temperature
		local idp = 2
		local mult = 10^(idp or 0)
		local precurrtemp	= tonumber(tempd.temperature)	
		local diff = tonumber(precurrtemp - prevt)		
		local currtemp = math.floor(precurrtemp * mult +0.5) / mult

		local diffround = math.floor(diff * mult +0.5) / mult
		diffd.updateTemperature(diffround)
				domoticz.log('Current temperature in bathroom is ' .. currtemp, domoticz.LOG_INFO)
				domoticz.log('previous temperature in bathroom was ' .. prevt, domoticz.LOG_INFO)
		domoticz.log('Difference is ' .. diffround, domoticz.LOG_INFO)
        domoticz.data.prevtbath = currtemp
		 
		end
}

Yes, thank you!
I found the problem, you can not use Persistent data directly. When I created a local variable as you did, then it worked!

Code: Select all

local prevt = domoticz.data.prevtbath

[Doler]

It would already have worked if you had changed

Code: Select all

if (barometer) ~= (barometer_old) then

into

Code: Select all

if (barometer) ~= (domoticz.data.barometer_old) then

. No special need to put it into a local variable other than nicer code.

Correct, thx!
