Energy Monitoring DIN dev release

This device was developed by the robotonomics community. The main idea that prompted the creation of this device is the rejection of cloud solutions from manufacturers of IOT devices. Join the community and purchase a device. https://robonomics.network/devices/ We will be glad to see anyone who wants to develop the project of this device.

Notes for operation:

Energy monitoring is **the process of monitoring energy consumption, whether that's an individual asset or an entire building**. Energy monitoring software provides vital insight that can help to control and conserve energy in the future.
The Energy monitoring works on the local and does not access the cloud.
The Energy monitoring works with the Home Assistant using the MQTT protocol. To configure the device, please visit: https://tasmota.github.io/docs/MQTT/

Hardware specification

- Input Voltage: AC 100-240V 50/60Hz
- Measuring Range: 0.1-80A
- Wireless protocol: IEEE 802.11b/g/n (2.4 GHz Wi-Fi)
- CPU: ESP32-S3 MCU-based system on a chip (SoC) dual-core microprocessor (Xtensa® 32-bit LX7), up to 240 MHz
- Memory: 448 KB ROM, 520 KB SRAM, 8 MB FLASH
- USB-C for firmware development and updates

Attention, to prevent damage to the equipment, do not connect the device to the PC when the device is powered by 220 volt AC power.

Firmware:

The Energy monitor runs Tasmota, an open firmware distributed under GNU GPLv3.
The firmware can be upgraded (flashed) via USB-C or OTA.

The firmware is available at the link webflasher.robonomics.network

Cautions

Safety:

In general, a CT must **never** be open-circuited once it’s attached to a current-carrying conductor. A CT is potentially dangerous if open-circuited.

If open-circuited with current flowing in the primary, the transformer secondary will attempt to continue driving current into what is effectively an infinite impedance. This will produce a high and potentially dangerous voltage across the secondary [1]

Some CT’s have built-in protection. Some have protective Zener diodes as is the case with the SCT-013-000 recommended for use in this project. If the CT is of the ‘voltage output’ type, it has a built in burden resistor. Thus, it cannot be open-circuited.
