Select your board from the Tools -> Board menu.Search for ESP32 and install the esp32 platform. Enter the URL into the Additional Board Manager URLs field, like in the example below:.Start the Arduino IDE, and configure the espressif ESP32 repository: open the File menu -> Preferences.Download, install and open the Arduino IDE.We detected problems when uploading the sketch to some ESP32 mcu’s where all the hardware was already wired, an the problems where gone when disconnecting all the peripherals. We recommend to upload the sketch to the ESP32 before connecting the relay/temperature sensor. You have to decide if the ESP32 will be a temperature node, a relay node or a hybrid node, and upload the corresponding sketch using the Arduino IDE. The next step is to upload the appropriate sketch to the ESP32. You can download a zip file with all the available sketches from our resources page. There are three sketches, depending on which type of node you are planning to assembly. Before uploading them to the sketch, don’t forget to configure your Wifi SSID and password, and the name for the node. But you can have only one relay per thermostat and boiler.ĭepending on which nodes do you need, you will have to upload a specific sketch to the ESP32. You can place this node directly connected to the boiler.Īnd of course, you can add as many temperature/humidity nodes as you want. Two-Channel High-Level Relay connected to an ESP32 MCU.
