It's not that other energy monitors are bad, but they are different in that they are mostly closed systems that provide limited data and require that you use their cloud and phone app platforms. IoTaWatt collects many more metrics and stores that usage history locally. With it's integrated web-server you can manage setup, view real-time status or create detailed graphs using the browser on your computer, tablet or phone. It's your data, in your own home, and subject only to your own privacy and retention policy. You don't need the cloud to get a handle on your hot-tub, EV, solar or heat-pump.
IoTaWatt can, however, easily upload usage data to any of several third party databases with associated apps and analytic tools. For instance PVoutput is a free service that connects easily with IoTaWatt and provides world-class solar energy analytics. There is full support for uploading to influxDB. There is also an API interface for those who want to query data for their own applications or to use in spreadsheets, and there are integrations available for home automation software like Home Assistant.
Can be used to monitor just about any power system on the planet. USian 120/240VAC, European, 230 VAC single-phase, 230VAC three-phase in Australia, Germany, and Norway.
IoTaWatt measures each circuit using a passive sensor that clips around one of the insulated wires. The output of each of these current-transformers is very low-voltage and plugs into any one of IoTaWatt's 14 inputs. Sensors plug into the unit with regular phono plugs.
Fully tested and in compliance with regulatory and safety standards of North America and Europe.

If you only want to monitor power for the whole house, you only need the base kit and two induction sensors (one for each side of the split-phase). $260us
A compact and portable WiFi reconnaissance suite based on the ESP8266. Packet Monitor with 11 filter types. Deauthentication and Disassociation Detector (HAXX). FTP Honeypot with Canary Tokens. Web Server (WIP). CSV Data logging (WIP).
The custom PCB is basically glue for two pressbuttons, an OLED display, an LED, and a power cell. You could pretty easily bodge one together out of spare parts.
Tasmota is an open source firmware for Espressif ESP8266, ESP32, ESP32-S or ESP32-C3 chipset based devices created and maintained by Theo Arends.
Everything began as Sonoff-MQTT-OTA with a commit on 25th January 2016. by Theo Arendst. Its goal was to provide ESP8266 based ITEAD Sonoff devices with MQTT and 'Over the Air' or OTA firmware.
What started as a simple way to hack a cloud bound Sonoff Basic (one of the first cheap and accessible smart home devices in the market) into a locally controlled device has grown into a fully fledged ecosystem for virtually any ESP8266 based device.
ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems.
A Playstation 1 Modchip written in Python. Contribute to ColdHeat/PsNeePy development by creating an account on GitHub.
Alternative firmware for ESP8266 and ESP32 with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Written for PlatformIO with limited support for the Arduino IDE.
Seems to automatically update itself from a known-good location. That can probably be turned off.
A Python-based, open source, platform independent, utility to communicate with the ROM bootloader in Espressif ESP8266 & ESP32 chips. Python 2 and 3 compatible. Can use this to dump the firmware for analysis. Depends upon pySerial.
