APsystems intégration ECU 2160XXX

[jfmarquis (MARQUIS)]

Hi there
I’m trying to ingest data from my APsystems solar panel
Panel information:

• EMA V5.5.0
• ECU 2160XXX
• Inverter Type DS3
  I’ve tried 2 intégrations :

1. GitHub - bgbraga/homeassistant-apsystems: An APsystems Sensor for Home Assistant

2. GitHub - ksheumaker/homeassistant-apsystems_ecur: Home Assistant custom component for local querying of APSystems ECU-R Solar System

3. setup seems to be correct but I’ve this in the log :
   

   
   
   I’m not sure of the authId. don’t find any doc to understand where to take it

4. Even in wifi or in wired i’m able to validate access with nc command :

nc -v 192.168.1.51 8899
nc: connectx to 192.168.1.51 port 8899 (tcp) failed: Connection refused

can someone explain me why wifi connection is needed ?
did someone has the same problem ? how did you connect your homeassistant to ECU or apsystems online ?
thanks for your help
have a nice day

Have you read this fantastic thread explaining how to connect an ECU-R 2160xxx with home assistant?

APsystems APS ECU R local inverters data pull

So i’ve been looking around to have solar data inside HA without using cloud api from APSystems. The newer versions of the ECU-R dont have a webinterface anymore, so that was no longer an option. Together with some other folks, I first started to trace the data pull from their own ECU app, which normally only connects when the local WIFI SSID is enabled. This showed it pulled binary data over TCP layer on port 8899. After some time we found most bytes to be usefull and i created a first python …
