### PowerflyESP
|
|
|
|
This is a custom version of EmonESP modified by CircuitSetup to include ATM90E3X library and modified once again for our own needs.
|
|
Not necessarily intented to be used by anyone else but released publicly as some parts can be useful. You're welcome to fork and/or contribute.
|
|
|
|
Mostly used to prepare for others versions of the hardware :
|
|
- More CT per board (12, 18 ?)
|
|
- Easier stacking
|
|
- Revamped powering with three-phase
|
|
|
|
Some notes:
|
|
- You must use an ESP32
|
|
- To compile, you must have the [ATM90E32 Arduino library](https://github.com/CircuitSetup/Split-Single-Phase-Energy-Meter/tree/master/Software/libraries/ATM90E32) in your Arduino libraries folder.
|
|
- If you need to calibrate a specific voltage channel on an add-on board, by default the values from the main board calibration are used, so they would need to have a seperate variable defined, and set manually in energy_meter.cpp
|
|
|
|
For details on setup, please see the [readme under the Split Single Phase Energy Meter.](https://github.com/CircuitSetup/Split-Single-Phase-Energy-Meter/tree/master/Software/EmonESP)

### Changes from CircuitSetup's EmonESP
|
|
- Some branding changes
|
|
- Added Home Assistant MQTT auto-discovery (https://www.home-assistant.io/integrations/mqtt/#mqtt-discovery) (Thanks @plapointe6 !)
|
|
- Moved config storage from (deprecated) EEPROM library to Preferences
|
|
- Slightly changes in networking to make unique and consistent mDNS, DHCP client, MQTT and wifi client name
|
|
- Add some defaults to MQTT
|
|
- Allow reset of Wifi client config only
|
|

### To do
|
|
- [ ] Get voltages from add-on board(s)
|
|
- [ ] Set voltage calibration for add-on boards
|
|
- [ ] Allow calibration for add-on boards voltages
|
|
- [X] Move calibration storage from EEPROM to Preferences library
|
|
- [X] Display complete MQTT client name with MAC on web page
|
|
- [X] Change DHCP hostname to match MQTT client name
|
|
- [X] Default MQTT base-topic to enerwize/<hostname>
|
|
- [X] Default MQTT server to 'homeassistant.local'
|
|
- [ ] Correct Firmware web page content to point to this repository
|
|
- [ ] Add web server button to switch quickly from 230V 50 Hz to 120V 60Hz and vice-versa
|
|
- [ ] Reduce HAMqttDevice refresh rate (only needed once at startup)
|
|
- [X] Make OTA works (partition scheme ?)
|
|
- [ ] Debug 'save failed' message
|
|
- [ ] Show IP address as MQTT topic
|
|
- [ ] Reduce log verbosity on serial
|
|
- [X] Change port number to always use 2 digits for correct sorting
|
|
- [X] Display active power as 'VA' on web interface
|
|
- [ ] Add auto-calibration method
|
|
- [ ] Rewrite OTA system
|
|
- [ ] Support ESP32-S3
|
|
- [ ] Move from SPIFFS to LittleFS
|
|
- [ ] Drop support for ESP8266 (shouldn't work though)
|
|
