About

E3DC Remote Storage Control Protocol (Git) is a custom integration that connects Home Assistant to E3DC home storage systems. It talks to the unit over the RSCP protocol and is based on python-e3dc. It adds binary sensors, buttons, numbers, sensors and switches, covering things like battery charge, autarky, power limits, weather regulation, sun mode and wallbox settings. Actions can set or clear power limits, set the power mode, set the wallbox charge maximum and start or stop manual charging. Authentication works with either an E3DC portal account or the offline local user on the device, plus an RSCP encryption key. Options include creating battery devices and a polling interval for power and status values. Home Assistant can discover the device on the network, and it is added as a custom repository in the Marketplace.

Setting it up

Add its repository to the Marketplace as a custom repository and install it, then restart Home Assistant and add it under Settings, Devices and services.

E3DC authentication type

Authentication typePortal-User: Use your E3DC portal account (email + password). Local user: Use the offline RSCP user (username is fixed to 'local.user', password configured on the device under Personalize → User profile → Password for offline RSCP user).

Also asked when at the discovered e3dc device step.

E3DC credentials

Host or IP addressIP address or hostname of the E3DC device on your local network (e.g. 192.168.1.100).
Username (E3DC portal email)Your E3DC portal email address (only for Portal-User).
PasswordPortal-User: your E3DC portal password. Local user: the offline RSCP user password set on the device (Personalize → User profile → Password for offline RSCP user).
RSCP encryption keyThe RSCP encryption key configured on the device (Personalize → User profile → RSCP password). This is the encryption key, not a login password.

Updating E3DC credentials

Authentication typePortal-User: Use your E3DC portal account. Local user: offline RSCP user (username: local.user).

Also asked when changing the connection.

After setup

Create battery devices
Update intervalHow often power and status values are polled from the E3DC (5–60 seconds). Daily statistics stay on their own schedule.

From the README

This integration will interface with the E3DC Storage systems supprting the RCSP protocol. It is based on python-e3dc. This repository delivers the latest features via HACS. You can use it for testing until I can get the integration accepted to HA core (no timeline for that, sorry).
If you encounter problems, please file an issue at the integrations issue tracker. If possible, add a diagnostics dump always. This is important also for enhancements if they target new data or information to be retrieved from the unit to see what it has to offer. Always check that dump if you want to further redact information in it.
