Supports only ONE inverter!
Supported inverters, with serial number begin:
Hoymiles HM inverters are supported in this project: https://github.com/lumapu/ahoy/
This software is a QUICK&DIRTY SW for debugging/controlling the Hoymiles inverters over RF, tested with:
Radio, CRC, part of Web based on the orig. SW from Hubi's earlier stage from this (https://github.com/hm-soft/Hoymiles-DTU-Simulation).
Project initiated here: https://www.mikrocontroller.net/topic/525778
Do not expect any quality from this SW!!!
Issues can be reported on https://www.mikrocontroller.net/topic/525778, but do not expect any answer immediately!!!
As far as you know what you are doing, you can use this SW.
Runs on ESP8266: wifi, mqtt, shows all data on serial monitor and on web site
https://github.com/lumapu/ahoy/blob/main/Getting_Started.md#things-needed
For zeroexport, it needs a sep. mqtt connection with a topic "ImpExpW" to a Chint-DTSU, see mqtt.h . I had to choose the topics so, because of an earlier implementation on RS485 modbus DTUPro<>DTSU666 in my house. You can change it as you like! If you change the topics, be sure change the PV numbers everywhere!
Define mostly everything in settings.h and secrets.h
Please SEE the issues !!!
VERSION "V0.1.5"
- using secrets.h for SSID,PW etc.
- stay on same RxCH until no Rx OR gets a rxtimeout
- fine tuning on zeroexport
- update timer for checkPV,zeroexport, webservice, mqtt
- Tx only if its daytime (only with Wifi, otherways always Tx)
- new mqtt id
- still issues with Rx-irq, no issues with Rx-polling
VERSION "V0.1.6"
- fixed limiting the wr over WR_LIMITTED in settings.h
- more data moved to settings.h
- several enhancements
VERSION "V0.1.7"
- new file "Globals.h"
- automatic recognition the inverter (MI) model,power and ports
- several changes for stability
- zeroexport with % of reated power OR absolute power
VERSION "V0.1.9"
- no irq issues anymore
- significant modifications
- a lot of enhancements
- more serial commands for inverter, type 1 help on console
- mqtt reconnect
- JSON string to mqtt
VERSİON "V0.1.9.1"
- changed max. power of one MI.port
