Help. I have a problem with hub.get() command in LUA in my scene

[Herni 3]

                Hi Everybody,

 

                I have a problem. I´m trying to measure the difference time between the change state of the S1 channel of a double switch. 

                Therefore, in my scene is using the hub.get () command to extract "lastmodificationtime" of the value of the channel (see the picture below):

               After to extract the "lasttime1" value i compare the os.time() value with "lasttime1" value (to compare the time from high state to low state) (see picture below) 

 

 

The problem is the if(tonumber(os.time() - lasttime1) sentence. I´m not sure if the problem is the data type used or not. But i can´t do that the if(tonumber(os.time() - lasttime1) sentence ejecute correctly. Could anybody help me? Thanks in advance. Best regard.

Try to add a debug statement before the test to see if you have the values you expect

Hi Jgab,

 

Thanks for the reply. I tried a debug statement (see the picture below),

I think that the problem is the hub.get(25, "value") statement because the lastime1 value is 21:00:00, is not near to 19:20:23. I hold the momentary switch only a few seconds to test. I don´t know where is the problem yet. Thanks in advance.

Yes, the problem is lasttime1,  it's not a full time, like os.time(). Its a much smaller value (you see the diff is almost a full time value)

Are you sure you are running the IF branch that is getting the value?

Put a debug directly after

Hi Jgab,

 

I´m not sure. Because in the original script first i put the "a =hub.getValue(25,"value")" statement to capture the id = 25 value. After that i use the "a, lasttime1= hub.get(25,"value");" statement to capture lasttime1 value (when the rise edge to double switch is present). Homever i´m not sure if the first time when the "a =hub.getValue(25,"value")" statement is used it clear the lasttime1 value and the second time when the "a, lasttime1= hub.get(25,"value");" statement is used lasttime1 obtain another value. 

Otherwise, 

Homever, i have done that you asked me (see picture below)

I´m running only the "hub.debug("SCENE6","lasttime1:",lasttime1)" statement after the "a, lasttime1= hub.get(25,"value");" statement to see the time values of rising and falling edge ( see the marks 1 and 2 in the console).  I don´t understand the format of these values. When i do the arithmetic operation of these value i think that the result must be a few seconds (1, 2 or 3 seconds depend how much time i hold down the momentary switch). But the result is not as expected. Thanks.

Hi Jgab,

 

The problem is the scope of the variable "local" lasttime1. When the momentary switch is pressed the first time the local lasttime1 variable value save the system time. But it variable have a local scope. When the momentary switch is released the script begin to run again and the local lastime1 variable reset to 0 value (see the picture below)

I have change script and the declare in the variable panel of the Yubii Home Controller, the global variable "lasttime1" to hold the first value in memory (see picture below). But the result of the difference of the values is 0 now. In the picture the difference time between rising and falling edges is 2 seconds. I don´t know where is

the problem now. Could you help me with it?

Hi Jgab,

 

The problem was resolved. The problem was the data type of the operands (lastime and lastime2 (or the value returned of the os.time() function). See the picture below.
