Telegram Phone Calls from OpenHab (with Voice Messages)

Yes! Now OpenHab can make a Telegram phone calls (with Voice) thanks to the CallMeBot API. You just need OpenHab to execute the following command to get a Telegram Voice call and "read" your message with different voices:

http://api.callmebot.com/start.php?source=openHAB&user=@username&text=This is openHAB calling to you to inform you about something that is happening at your house&lang=en-GB-Standard-B

Parameters:
user is your Telegram Username/Alias (i.e. @myusername) or you can also use your phone number including the international code. Important!: You need to authorize CallMeBot to contact you here. This is required to avoid spam.
text is the message that you want the bot to speak.
lang is the language/voice that you want the bot to speak. You can get the list of languages here. Use the "Voice Name" (4th column) as parameter to use. Please note that only the Standard languages are supported. (Wavenet premium languages/voices  won't work with this API).

For example, calling to @myusername and speak the message in English with a Male voice:

wget 'http://api.callmebot.com/start.php?source=openHAB&user=@myusername&text=This is openHAB calling to you to inform you about something that is happening at your house&lang=en-GB-Standard-B'

For example, calling to +34 123 123 1123 and speak the message in Spanish:

wget 'http://api.callmebot.com/start.php?source=openHAB&user=+33 123 123 1123&text=Este es openHAB llamando para informar sobre algo que esta sucediendo en tu casa&lang=es-ES-Standard-A'

To do that in OpenHab is pretty easy! You have different ways to do it.

Code:

var HttpUtil = Java.type("org.openhab.core.io.net.http.HttpUtil")
var urlmessage = encodeURI("This is a test from openHAB calling you becaue something is happening in your house")
HttpUtil.executeUrl("GET", "http://api.callmebot.com/start.php?source=openHAB&user=+34123123123&text=" + urlmessage , 2000)

Use the sendHttpGetRequest action like this:

import java.net.URLEncoder

   Item TestCall changed to ON
then
   val urlmessage = URLEncoder::encode("This is a test from openHAB calling to you becaue something is happening in your house", 'UTF-8')
   SendHttpGetRequest("http://api.callmebot.com/start.php?source=openHAB&user=+34123123123&text=" + urlmessage)
end
