Advanced EcoFlow Configuration & Hacks

This guide covers advanced usage, including automation and potential hidden resets.

🤖 Home Assistant Automation: Solar Excess Charging

Maximize your solar investment by only charging your EcoFlow when you have excess solar power, instead of pulling from the grid.

The Logic

Monitor: Read your Home Energy Meter (e.g., Shelly EM, Emporia Vue) to see “Grid Export”.
Trigger: If Export > 200W for > 1 min -> Start EcoFlow Charging.
Control:
- Method A (Smart Plug): Turn ON a smart plug powering the EcoFlow AC input.
- Method B (Direct API): Use the hassio-ecoflow-cloud integration to set acChgCfg_D2 (AC Charge Speed) dynamically.

Example Automation (YAML)

alias: EcoFlow Solar Excess Charge
trigger:
  - platform: numeric_state
    entity_id: sensor.grid_power
    below: -300  # Negative value usually means export
    for: "00:01:00"
action:
  - service: switch.turn_on
    target:
      entity_id: switch.ecoflow_ac_input
  - service: number.set_value
    target:
      entity_id: number.ecoflow_delta_max_ac_charging_power
    data:
      value: 400

🔁 Hard Resets & Key Combinations

EcoFlow devices generally lack a visual “service menu”, but they use button combos for hard resets.

1. The “Long Press” (General Reset)

Target: All Delta/River units.
Action: Unplug EVERYTHING (Inputs/Outputs). Hold the main yellow Power Button for 10-15 seconds.
Result: Cold reboot of the BMS and LCD communication.

2. IoT Reset (Wi-Fi/Bluetooth)

Target: Delta 2, Delta Max, Delta Pro.
Action: Hold the IoT Button (or pair button) for 3-10 seconds until the Wi-Fi icon flashes.
Use Case: Moving the device to a new Wi-Fi network or if the app refuses to connect.

3. DC + Main (River Pro Reset)

Target: River Pro (Older).
Action: Unplug unit. Hold LED Light Button + DC Button simultaneously for 10s.

4. BMS Calibration (The “Drain & Fill”)

Issue: Screen shows 30% but unit dies instantly.
Fix:
1. Charge to 100% until input watts hit 0.
2. Discharge to 0% until unit shuts off completely.
3. Wait 2 hours (thermal normalization).
4. Charge uninterrupted back to 100%.
  - This recalibrates the SoC (State of Charge) algorithm.

🔒 Service Ports

Most units have a hidden Micro-USB or USB-C port often covered by a plastic flap (sometimes near the handle or inside the lid of older units).

Purpose: Factory firmware flashing.
Usability: Generally encrypted/protected. Not a user-accessible console without specific proprietary tools.
