This project is for reading APS Systems inverters. The program can pair and poll YC600 QS1 and DS3 inverters, up to 9 pieces. 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.
See the WIKI for information on building it, the working, etc.

In case someone wants to print the housing, here is an stl file
This is for a nodemcu board 31x58mm.
- Simply to connect to your wifi
- 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 4 different mqtt json formats
- Fast asyc webserver
- a very smart on-line console to send commands and debugging
- 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-v9_4 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
For info on how to build and use it, please see the WIKI
APS works with their own zigbee implementation. The ESP-ECU sends zigbee commands (wireless) to the inverters and analyzes the answers, extracting the values. The ESP communicates with the zigbee module through the alternative serial port (wired). 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.
version ESP-ECU_V9_6:
- added 2 mqtt json formats, numeric values are included as float now.
- changed the format of the returned json when http request.
version ESP-ECU_V9_5:
- added a mqtt command for polling all inverters
- added a signal quality value
version ESP-ECU_V9_4:
- fixed failed polling after power cycle
- fine-tuned some dc values of the DS3
- default conversion factor now 1.66
version ESP-ECU_V9_3:
- fixed a bug with a negative poll offset
- added the poll- begin and end time on the main page
version ESP-ECU_V9_2:
- made it suitable for the DS3 inverter.
- fixed polling intervall of 5 minutes.
- bug repaired, sq1 dc data panels 2 and 3
As of version 8 the value of total energy is no longer directly comming from the inverter's register. Instead all energy increases are added up in a total energy value. This way that value is not sensitive to inverter resets that will happen in twilight or due to an eclips etc.
