Advanced settings can wait
The default values are fine for your first tests: adjust later, one setting at a time.
Getting started
When first opened, a wizard asks you a few questions. Here they are, so you can prepare your answers. Every step can be skipped and changed later in the settings. The interface is in French for now: menu names are given as they appear, with their meaning.
Home Assistant OS: TedEnergy entry in the sidebar. Synology or Docker: http://MACHINE-ADDRESS:5002 (or the port you chose).
First name and email: the license is obtained and activated automatically. Without a license, regulation stays on standby and controls nothing.
Without Home Assistant (Zendure through the cloud and a Shelly or MQTT meter): skip this step. Home Assistant OS: automatic, nothing to enter. Synology or Docker: two pieces of information.
http://192.168.1.50:8123.Click Tester la connexion (test connection): a message confirms that Home Assistant answers.
Pick the meter's power entity from the suggested list (or a Shelly by its IP address), then Tester la lecture (test reading). Tip: switch on a kettle, the value must go up.
MQTT meter, or no meter yet? Click “Passer” (skip). Connect the device in Settings › Connexion MQTT (for example the Zendure Smart Meter 3CT), then declare it in Settings › Compteur électrique (electricity meter). You can rank several meters by priority there: if the first stops answering, the next one takes over.
Supplier and contract, Autonome or Assisté mode (when in doubt, keep both), contract power and battery levels.
Onduleurs (inverters) tab › add: pick the device entities (for Zendure, Autoremplissage finds them). Type piloté (controlled: it receives setpoints) or surveillé (monitored: read only). Regulation then starts.
Zendure without Home Assistant: Paramètres (Settings) › Connecteurs d'appareils, paste the Zendure app token; your devices then appear in the inverter form's list. MQTT devices: Paramètres › Connexion MQTT.
Getting it right
The default values are fine for your first tests: adjust later, one setting at a time.
Check that it follows the setpoints, then add the others.
You are responsible for your electrical installation: keep cautious maximum powers.
The show home shows the real interface, on an installation in service.
