## OVERVIEW
|
|
|
|
This code is intended to run on a Wemos D1mini or similar. The code is based on 'Hubi's code, which can be found here: <https://www.mikrocontroller.net/topic/525778?page=3#7033371>
|
|
|
|
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 from the /setup URL
|
|
|
|
|
|
## Compile
|
|
|
|
This code can be compiled using Arduino. 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 Arduino Time library (TimeLib.h)
|
|
- RF24 Optimized high speed nRF24L01+ driver class documentation
|
|
- PubSubClient A client library for MQTT messaging. By Nick O'Leary
|
|
|
|
### Optional Configuration before compilation
|
|
|
|
- number of supported inverters (set to 3 by default) `defines.h`
|
|
- enable channel hopping `hmRadio.h`
|
|
- DTU radio id `hmRadio.h`
|
|
- unformated list in webbrowser `/livedata` `defines.h`, `LIVEDATA_VISUALIZED`
|
|
|
|
|
|
## Flash ESP with firmware
|
|
|
|
1. flash the ESP with the compiled firmware using the UART pins or any preinstalled firmware with OTA capabilities
|
|
2. repower the ESP
|
|
3. the ESP will start as access point (AP) if there is no network config stored in its eeprom
|
|
4. connect to the AP, you will be forwarded to the setup page
|
|
5. configure your WiFi settings, save, repower
|
|
6. check your router or serial console for the IP address of the module. You can try ping the configured device name as well.
|
|
|
|
|
|
## Usage
|
|
|
|
Connect the ESP to power and to your serial console (optional). The webinterface has the following abilities:
|
|
|
|
- OTA Update (over the air update)
|
|
- Configuration (Wifi, inverter(s), Pinout, MQTT)
|
|
- 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)
|
|
|
|
|
|
## Compatiblity
|
|
|
|
For now the following inverters should work out of the box:
|
|
|
|
- HM400
|
|
- HM600
|
|
- HM800
|
|
- HM1200
|
|
|
