E3DC Binding (beta)

CortezTheKiller · October 3, 2023, 7:24am

Thanks for the Help, the binding ist running now.
Is there a way to manually stop discharging the battery? I didn´t see a channel that refers to “entladesperre” like in the e3dc web portal.

Can the plugin be installed in parallel to the E3DC modbus plugin? I’ve installed both and both are shown as active in karaf console but I can not create a thing based on this pluging.
Thanks a lot for your work, great that it is going on.

I´m on OpenHAB 4.0.4.
Installed the binding via WebUI, latest JAR/KAR in addons folder. No success. Here´s the output of org.openhab.binding.e3dc-4.1.0-SNAPSHOT.jar

Any idea?

I fail using this binding on oh 4.1.1:

copied .kar as of Aug 29th to addons folder, found binding in Main UI in Thing creator, started config. Connection cannot be established (“No data received for authentication request”, log below), although other rscp tools work well with same credentials
After using the .kar file, Addon Store reports “E3DC Binding” in Distribution section installed. This binding doesn’t exist elsewise.
alternatively chose (beta) plugin from Community Marketplace, same issues: no connection established and now both a Marketplace and again e3dc binding (non-beta) appears “installed” in Distribution bindings in parallel. After uninstall of Marketplace binding (beta), also instance in Distribution section is removed.
Using the .jar doesn’t present a binding in Things creation
After a restart of openhab, created e3dc Thing shows up with empty screen. Need to remove .kar and re-add again to addons folder, or uninstall/install from Marketplace.

Log for not established connection:

I switched over to rscp2mqtt, works like a charm.
It´s a deamon, which speaks RSCP with E3/DC and on the other hand you can read/write messages via MQTT.
It has integrated functionality for limiting discharging (use it for surplus charging my wallbox and other consumers), reporting, etc. Stable running for months now.
