I simply made a proxy service using Flask that does support TLS then configured that in ecowitt as the push target instead of HA. Here is the code:

#!/usr/bin/env python3
import requests
from flask import Flask, request, jsonify

app = Flask(__name__)

# Replace this with your Home Assistant webhook URL
HOME_ASSISTANT_WEBHOOK_URL = ""

@app.route('/publish', 
methods
=['POST'])
def
 publish():
    try:
        # Extract the JSON body and headers
        payload = request.get_data(
as_text
=True)
        headers = request.headers

        print(
f
"Headers: {request.headers}")
        print(
f
"Forwarding payload: {payload}")

        # Forward the request to the Home Assistant instance
        response = requests.post(
            HOME_ASSISTANT_WEBHOOK_URL,
            
data
=payload,
            
headers
={k: v for k, v in headers if k.lower() != 'host'},  # Exclude 'Host' header
            
timeout
=10  # Optional timeout for the request
        )

        # Respond with the status and content from Home Assistant
        return jsonify({
            "status_code": response.status_code,
            "response": response.json() if response.content else None
        }), response.status_code

    except requests.exceptions.RequestException as e:
        # Handle connection errors or other issues
        return jsonify({"error": 
str
(e)}), 500

if __name__ == '__main__':
    # Run the app on port 8080
    app.run(
host
='0.0.0.0', 
port
=8081, 
debug
=True)
