This project is intended for reading APS Systems inverters. The program can pair and poll YC600 and QS1 inverters, up to 9 peaces. The read values are displayed on a web page and sent via mosquitto in a Json format. The program has a lot of smart features. All settings can be done via the webinterface. It has a console that can be used for debugging and sending/receiving zigbee messages.

In case someone wants to print the housing: https://1drv.ms/u/s!AkMG5FvUwhedim8a_tVLywAivVDI?e=XIwhYg This is for a nodemcu board 31x58mm
- Easy wifi config portal
- Easy add, delete and pair inverters
- automatic polling or on demand via mqtt or http
- data can be requested via http and mosquitto
- There are 2 different json formats, a special one for domoticz
- Fast asyc webserver
- a very smart on-line console to send commands and debug
- Smart timekeeping
- A lot of system info on the webpage
Use arduino ide with the esp822 version 2.7.1 installed under boardmanager. The ota updates won't work with other versons.
Or use the binary file ESP-ECU-v6_12 to flash directly on your ESP device.
It is nothing more than an esp device like nodemcu, wemos or its relatives and a prepared cc2530, cc2531 zigbee module. And a powersupply. The zigbeemodule should be flashed with a firmware that can be found here Koenkk/zigbee2mqtt#4221. Here you can find much more information on this project. The most recent link to a lua implementation (including firmware) by kadszol :https://github.com/Koenkk/zigbee2mqtt/files/6797510/discord-11-7-2021.zip
A compiled binary of this software, firmware and additional information can be found here: https://1drv.ms/u/s!AkMG5FvUwhedimnUoBjQROkAaofW?e=zFgWdM,
the wiring:
- p2 -> d8
- p3 -> d7
- vcc -> 3.3v
- gnd -> gnd
- rst -> d5
The APS system works with a separate zigbee implementation. The ESP-ECU sends zigbee requests to the inverters and analyzes the answers, extracting the values. The ESP communicates with the zigbee module through the alternative serial port. The ESP-ECU starts a coordinator (an entity that can start a zigbee network). The coordinator binds the inverters and sends the poll requests to them. The interesting values are send via mqtt and displayed on the main page.
The zigbee module crashes sometimes during the pollings. The system recovers that by resetting it and start the coordinator again. This is done by a healthcheck that runs every 10 minutes. You can only notice this via the log and infopage where this is counted.
