Have a virtual device display a value from a file on LAN web server

[fel-x 7]

Hi guys

Using HCL, i would like to have a virtual device display a value.

that value is in a file on my raspberry's LAN apache WEB server.

 

Let’s say 192.168.0.123 is my raspberry and the file is http://192.168.0.123/prod.txt

 

the file contains just a number, and it’s updated every hour using a cron job.

for example it could be « 2 » at 8AM, then « 19 » at 9AM, then « 55 » at 10AM, then « 156 » at 11AM, and so on...

It’s just an example, it could be the number of visitors on a website or the number of gallons of water I drink, or Power production of an engine... whatever!

 

my only concern is how to have a virtual module on HCL display that number? 

I don’t care if it’s not updated on HCL at the exact second it is updated on the web server... yet it should be updated somehow every hour also.

 

thanks for any help !

thanks I'll look into that !!

 

EDIT : problem SOLVED.

 

There is a way to send a value to a virtual device on HCL.

Here is my example working from a Raspberry that is on the same LAN :

 

Please login or register to see this code.

where LOGIN and PASSWORD are plain text login and password for HCL, like  [email protected]:secretpassword 

make sure to use your HCL IP address, deviceID (I used 123 in this exemple) and label (I used Label1, which is default on virtual devices).

You need to have the value in a variable, in this example the variable is $blahblah

It's also possible to have spaces in the value, by using %20 , so let's pretend $blahblah=13 and it would be like this: arg2='$blahblah%20minutes' 

(which would send "13 minutes" as the value to display in the virtual device)
