SolarEdge + Shelly Control

Description

This Python script controls a Shelly relay based on the grid feed-in from a SolarEdge inverter. If a specified feed-in power (e.g., 6000 W) is exceeded for 5 minutes, the Shelly device is triggered. A lockout period of 60 minutes follows before it can be activated again.

The log file is cleared daily at 1:00 AM to prevent it from growing indefinitely.

Requirements 📌

• Python 3.8 or later must be installed.

• Required Python packages:

pip install requests

• SolarEdge Monitoring API access:
  
  

  • Create an account on SolarEdge Monitoring.

  • Generate an API key under "Admin" → "Access Control" → "Create API Key".

  • Note your Site ID from the dashboard.

• Shelly device (e.g., Shelly Plus 1 or Shelly Pro 2):
  
  

  • Ensure the IP address of the Shelly device is known (e.g., 192.168.1.100).

  • Ensure the Web API is enabled.

• USOC data source (if used):
  
  

  • API URL and Auth Token required.

Setup 🔧

Edit the configuration variables in pvshelly.py:

SHELLY_IP = "192.168.1.100"

SOLAREDGE_API_KEY = "YOUR_SOLAREDGE_API_KEY"

SOLAREDGE_SITE_ID = "YOUR_SITE_ID"

USOC_URL = "http://192.168.1.50/api/v2/status"

HEADERS = {"Auth-Token": "YOUR_AUTH_TOKEN"}

Adjust the trigger thresholds to control the Shelly device according to your needs:

TRIGGER_THRESHOLD = 6000  # Feed-in power in watts

HOLD_TIME = 300  # Minimum duration in seconds

LOCKOUT_TIME = 3600  # Lockout time in seconds

Run the script:

python pvshelly.py
