[Bug]: Cannot connect to host 192.168.1.212:8050 ssl:default [The remote computer refused the network connection]

[paazevedo]

What happened?

While trying to execute the following example, I get an SSL issue:

from APsystemsEZ1 import APsystemsEZ1M # import the APsystemsEZ1 library
import asyncio

# Initialize the inverter with the specified IP address and port number.
inverter = APsystemsEZ1M("192.168.1.212", 8050)

async def main():
    try:
        # Get device information
        device_info = await inverter.get_device_info()
        print("Device Information:", device_info)

        # Get alarm information
        alarm_info = await inverter.get_alarm_info()
        print("Alarm Information:", alarm_info)

        # Get output data
        output_data = await inverter.get_output_data()
        print("Output Data:", output_data)

        # Set maximum power limit (ensure the value is within valid range)
        set_power_response = await inverter.set_max_power(500)
        print("Set Power Response:", set_power_response)

        # Set power status (ensure "ON" or other value is valid)
        set_power_status_response = await inverter.set_device_power_status("ON")
        print("Set Power Status Response:", set_power_status_response)

        # Get current power status
        power_status = await inverter.get_device_power_status()
        print("Power Status:", power_status)
    except Exception as e:
        print(f"An error occurred: {e}")

# Run the main coroutine
asyncio.run(main())

The python error

PS C:\Temp> python.exe .\EZ1.py 
An error occurred: Cannot connect to host 192.168.1.212:8050 ssl:default [The remote computer refused the network connection]

Your python version

3.11.8

Your OS inlcuding your version

Are you sure the IP address is correct? This error seems to occur when the IP is wrong.

[paazevedo]

Looks like. Unfortunately from the APSystems application I can't determine which IP\Mac address the device has, but from my unifi management I see it's apsystems. Used other techniques as well, as reconnect the device and see which devices joins the network for the less time. So I'm sure the IP address.

What happens if you open http://192.168.1.212:8050 ? It should give you an empty page saying "Nothing matches the given URI"

I'll give a try tomorrow and report back. I don't have more sunlight, the inverter just shutdown some minutes ago.

Ah, I know that! Tomorrow will be the last day I'll be able to help you until next weekend.

That's OK, I appreciate your input. Would you recommend other method to double check the IP address of the inverter ? It returned to life again (it's cloudy and rainning), but when I do http://192.168.1.212:8050/ the connection seems to be simply refused with ERR_CONNECTION_REFUSED. BTW, more information about the device, it's a EZ1 Version 1.7.0

Is the API activated in the app?

How do I check that sorry.

Can't tell you right now, but on the HA-integration docs, there's the German tutorial which should help you: https://github.com/SonnenladenGmbH/APsystems-EZ1-API-HomeAssistant

For that, you'll have to connect via Bluetooth to the inverter and enable it somewhere in the settings.

Appreciate your support! That was the problem. It's working now!

[mawoka-myblock]

No problem!
