What's App is free service
Considering you have line account and you already installed line on you phone/PC: To use automatic notifications you need to use a bot called callmebot, no worry no registration needed, just get some API Key.
1 - Add the phone number +34 644 95 42 75
into your Phone Contacts. (Name it it as you wish, I personally named it callmebot)
2 - Using your What's App, send this message I allow callmebot to send me messages
to the new Contact created.
3 - Wait until you receive the message API Activated for your phone number. Your APIKEY is 123123
from the bot.
Note
If you don't receive the ApiKey in 2 minutes, please try again after 24hs.
4 - Once API key is created you need to copy it
5 - Save the your phone number including country code as token 1 and the generated api key as token 2 in ESP3D, and set WhatsAPP as notification supplier
[ESP610]type=WhatsApp T1=336XXXXXXXXX T2=XXXXXXXX
Note
Do not put the internationnal prefix on the phone number, just prefix with your country code.
6 - type [ESP610]
to verify (T1/T2 won't be displayed)
7 - Try to send message:
[ESP600]Hi\ there,\ test\ from\ ESP3D
