ESP Easy

The ESP Easy firmware can be used to turn the ESP module into an easy multifunction sensor device for Home Automation solutions like Domoticz. Configuration of the ESP Easy is entirely web based, so once you’ve got the firmware loaded, you don’t need any other tool besides a common web browser.

WiFi On-board your network

When a fresh ESP Easy module boots up, it has no Wifi config and it will start as an Access Point. Use a Wifi enabled device (Laptop, Tablet, Smartphone,..) to search for Wifi access and try to find an access point with the name ESP_Easy_0 (prior to 2.0 the AP was named ESP_0). Connect to this access point with default password: configesp Launch your internet browser and it should find the captive portal hosted by the ESP module. You should get to this welcome screen:

IoTaWatt with FlexSensor v3

IotaWatttm is an open-hardware 14 channel WiFi connected electric power monitor. It’s based on the ESP8266 IoT platform using MCP3208 12 bit ADCs to sample voltage and current. The FlexSensor v3 can be equipped with an expansion card that carries all the same hardware as the IoTaWatt project. You can then follow the guidelines and install the same OpenSource software from the original project.
