In many Internet-of-Things (IoT) applications, it’s necessary to send alerts to the user in the form of messages. Typically, text messages are sent via WiFi or SMS. But sometimes text messaging is unavailable between devices. So, what if these messages could be sent via the IoT to a user’s WhatsApp or Telegram account instead?  In…

In this article, we will be creating a pet feeding system that can be controlled by WhatsApp. Components required Tools required/ libraries required Linux based machine Python-based WhatsApp API MQTT based Python IDE Arduino IDE Technical insights The complete project has three types of communication and devices. XMPP (WhatsApp, MQTT, and Arduino Serial) can also…

In this article, we will be controlling devices that do not support WhatsApp but support other communication protocols like MQTT, TCP, IMAP, etc. If a house is installed with home automation devices that do not support Whatsapp, we will communicate with these devices (controllers) using protocols supported by these devices. Thus, we will be able…

In this article, we will learn how to control our IoT home appliances using the messaging app WhatsApp to easily and effectively communicatie with those devices. So we will be sending WhatsApp messages to a number of “lights on,” and lights at our house will turn ON. Components required  Tools Required/ libraries required: WhatsApp API…
