README.md

OVERVIEW

This page describes how the module of a Wemos D1 mini and ESP8266 is wired to the radio module, flashed and how the further steps are to communicate with the WR HM series.

Compatiblity

For now the following inverters should work out of the box:

  • HM350
  • HM400
  • HM600
  • HM700
  • HM800
  • HM1200
  • HM1500

The NRF24L01+ radio module is connected to the standard SPI pins. Additional there are 3 pins, which can be set individual: CS, CE and IRQ These pins can be changed in the http:///setup URL or with a click on the Setup link.

Compile

This code can be compiled using Visual Studio Code and PlatformIO Addon. The settings were:

  • Board: Generic ESP8266 Module
  • Flash-Size: 1MB (FS: none, OTA: 502kB)
  • Install libraries (not included in the Arduino IDE 1.8.19):
    • Time 1.6.1
    • RF24 1.4.5
    • PubSubClient 2.8
    • ArduinoJson 6.19.4

Optional Configuration before compilation

  • number of supported inverters (set to 3 by default) config.h
  • DTU radio id config.h (default = 1234567801)
  • unformated list in webbrowser /livedata config.h, LIVEDATA_VISUALIZED

Alternativly, instead of modifying config.h, config_override_example.h can be copied to config_override.h and customized. config_override.h is excluded from version control and stays local.

Flash ESP with firmware

nodemcu-pyflasher (easy way)

  1. download the flash-tool nodemcu-pyflasher

  2. download latest release bin-file from ahoy_

  3. connect the target device with your pc.

  4. Set the correct serial port and select the correct *.bin file

  5. click now on "Flash NodeMCU"

  6. flash the ESP with the compiled firmware using the UART pins or any preinstalled firmware with OTA capabilities

  7. repower the ESP

  8. the ESP will start as access point (AP) if there is no network config stored in its eeprom

  9. connect to the AP, you will be forwarded to the setup page

X. configure your WiFi settings, save, repower Y. check your router or serial console for the IP address of the module. You can try ping the configured device name as well.

! ATTENTION: If you update from a very low version to the newest, please make sure to wipe all flash data!

Usage

The webinterface has the following abilities:

  • OTA Update (over the air update)
  • Configuration (Wifi, inverter(s), NTP Server, Pinout, MQTT, Amplifier Power Level, Debug)
  • visual display of the connected inverters / modules
  • some statistics about communication (debug)

The serial console will print the converted values which were read out of the inverter(s)

MQTT command to set the DTU without webinterface
