wget helper in automation?

7 years 11 months ago - 7 years 11 months ago #621 by Xavier
Hi,
Is it a way to send a wget command through automation? For me, it would be an easy way to send SMS alert for free.
My French provider (Free Mobile) offers an API that permit to send myself an SMS from the shell :
wget --ca-certificate=/usr/share/ca-certificates/freemobile/RapidSSLCABundle.crt -O /dev/null "https://smsapi.free-mobile.fr/sendmsg?user=xxxxxx&pass=yyyyyy&msg=RPi speaking..."
Response is :
--2015-02-25 20:40:02--  https://smsapi.free-mobile.fr/sendmsg?user=xxxxxx&pass=yyyyyy&msg=RPi%20speaking...
Résolution de smsapi.free-mobile.fr (smsapi.free-mobile.fr)... 212.27.40.200
Connexion vers smsapi.free-mobile.fr (smsapi.free-mobile.fr)|212.27.40.200|:443...connecté.

As you can see the wget returns only when SMS is sent, here it last 30s.
Is it a problem?

Use HttpGet in program. Se example how to control ESP directly with TCP - its very similar.

Hi,
Here is my script. It seems to compile OK but it doesn't work. I even suspect it makes silently crash EasyIot so that I have to restart the server when an error occurs. Do you see something wrong?
const String testNode = "N2S0";
const float maxValue = 65;
const float minValue = 45;
const String hiMsg = "RPi Alert.\r";
const String loMsg = "Alert closed.\r";

const String FreeID = "xxxxxxx";
const String FreePW = "yyyyyyy";

In current beta Automation can crash EasyIoT so put code in try catch. I fixed that in my development version and fix will be included in next release. Use console mode and console output to debug your program

It took me a while to understand this sentence :pinch: .
I didn't understand neither why I get no debug messages in the systemlogger.log...
Then I remember that I make EasyIoT run as a service, so no more stdout display.
When runing as an App (as you suggest), I get this:

OK! I'm no more in the dark, I see that my attempt to convert string to float fails at the first occurrence, because in France the decimal separator is a coma, not a dot a standard parse() don't work . And my NumberFormatInfo argument seems not taken into account.
Nota:
Timestamps tell that it takes between 30 - 60s for automation task to startup.

You can try p.DecimalValue property to read numeric value.
