Hi, I understand that you must uses your cell phone number to receive Whatsapp messages. I working with a system where other (a few) person must receive the same message (i.e. alarms, etc.). Is it possible to configure the appi to more than one cell phone and not mine ? regards, Esteban

Hi!
Follow your Blog. Some Articles are very helpfull and finished.
Also read the Article about ESP8266 sending WhatsApp.
Nice Intro, but in this case senceless.
Sorry, but this kind of Tutorial has no learningcurve, whatfor should it be?
Better to take an real example like you post at the End (send an alert message when a sensor reading is above or below a certain threshold).
This would be realy usefull!

Best Regards

Hola Sara Santos.

Mi pregunta he probado el esp8266-nodemcu-send-messages-whatsapp/
ESP8266 NodeMCU: Send Messages to WhatsApp
y funciona muy bien, y me llega los whatsapp bien. yo queria utilizar este codigo como el de ESP8266 NodeMCU Door Status Monitor with Telegram Notifications, pero para whatsapp, o sea cuando abra la puerta un mensaje de puesta abierta y cuando se cierre , puerta cerrada. Creo que serian pocas modificaciones. Ya me dice, muchas gracias por sus fantasticos proyectos y la pagina es un 100 , FELECIDADES.
Hello Sara Santos.
My name is Javier from Spain
I write to you in Spanish, I don’t think you have a problem.
My question I have tried esp8266-nodemcu-send-messages-whatsapp/
ESP8266 NodeMCU: Send Messages to WhatsApp
and it works very well, and I receive WhatsApp well. I wanted to use this code like that of ESP8266 NodeMCU Door Status Monitor with Telegram Notifications, but for WhatsApp, that is, when I open the door, a message shows it open and when it closes, the door is closed. I think there would be few modifications. You already tell me, thank you very much for your fantastic projects and the page is a 100, CONGRATULATIONS.

Thankyou for this tutorial, I made this for myself & it’s working awesome.
By the way is there any limit of number of messages per day or per hour of the api?

Thanks Sara Madam.
I will re install Arduino IDE in my laptop as you say.

Another point is, on 23rd August, the program was compiled ok on desktop but it is not getting compiled since 24th August onwards.
The following error is coming :

C:\Users\mentor\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.2/tools/sdk/include/bearssl/bearssl_rsa.h:3:150: error: extended character ⦫ is not valid in an identifier

Shall I reinstall Arduino IDE on my desktop also ?
Or, is there any other reason ?

Hi.
I’m not familiar with that error. But it seems an issue with your Arduino IDE installation.
I would remove all Arduino IDE folders and reinstall it again.

Sara
