Is it possible to advertise multiple SSIDs at the same time? For example - guest-net and local-net. The DHT22 is a very low-cost sensor. org // /* Author: Steven Prickett (steven. Multiple clients (browser, ESP8266) can connect to this Node. As far as I am aware there can not be multiple SSID's when done this way but it is convenient because the ESP8266 will join a WiFi network at anytime after power up that it becomes available and will rejoin if the WiFi network goes away and comes back later. In either case, the setup complexity is O(NxM) for N = number of SSIDs, M = number of devices. When the button is pressed, the browser sends a POST request to /LED. Every time I had a sequence of images and I wanted to create a time-lapse video, I used an old tool called TimeLapse Assembler, version 1. ESP32 Arduino HTTP server: Running multiple server instances The objective of this post is to explain how to use multiple HTTP server instances on the Arduino core, running on the ESP32. The value of this port will be random if it's not deﬁned beforehand. ESP8266 $5 Internet Connected Switch - Improved: In this tutorial we will show how to build WiFi internet controlled switch connected to EasyIoT Cloud. Here Arduino is not talking to ESP8266, it only powers the ESP8266 module & gives us a interface to send connection commands from our computer to the ESP. It does not support TLS certificate chain validation, and it uses TLSv1. Of course the code can be extended to have more than two SSID's , feel free to play with this. We'll show you how to wire the sensor, install the required libraries, and write the code to get the sensor readings from one and multiple sensors. When a wakeup is triggered (because ANY of the door GPIOs were triggered), read the state of the 4 door-GPIOs, act on it, then go back to sleep.
