# shellyEM mockup Base code for shelly EM energy meter Shelly EM is a impressive mini device that comes with the following features: - I2C RTC based on PCF85363A - I2C energy meter based on AD7953 - Relay - Button - LED - Esp 8266EX chip with 4Mb of flash This code serves as a buliding block to develop whatever you want on top of this great device. Check out the manufacturer, [shelly](https://shelly.cloud/shelly-energy-meter-with-contactor-control-wifi-smart-home-automation/) for features and hardware details. ## Disclaimer & instructions: - AC mains can **kill** you. You wont be able to undo any mistake after you're **dead**. - You **CANNOT** connect shelly to mains AC and to the programming pins at the same time. - Disconnect the device from any mains before program it with this firmware - provide your own WiFi, MQTT and Emoncms configuration and upload the firmware as a starting point. - Check serial UART for IP address, check if Emoncms and MQTT is working, disable the features you don't want on the code. - After everything is tested disconnect the programming pins and connect to AC mains and test again if the device is working properly. - From there you can change the code and do OTA updates to the ESP8266 using the url: `http://<ip_of_device>/update`  This code has the following features: - press button for 2 seconds to toggle relay. - LED follows Relay status - Communcate with ADE7953 and PCF85363A via I2C - Publish energy readings to emoncms server every 10s - Publish RTC time and energy readings to MQTT every 1s - WebUpdater.ino code included for easy updates OTA - http://<IP_address>/update  Have fun! If you find any improvements, like better calibration procedure or find any problems please open a issue.
