Unknown limit_status codes (3, 4, 0) causing MotionBlinds integration failure in Home Assistant

[Adoken1111]

Hi 👋 and thanks for maintaining this integration.

I'm facing a problem where my MotionBlinds-controlled curtain (connected through the Connector+ app and ESP-based motor) doesn't appear in Home Assistant as a cover entity.

Instead, I receive the following errors in the log:
💥 Problem Summary

limit_status codes '3' and '4' are logged as unknown.

The cover entity is not created.

A TypeError is raised because self._blind.position is returned as a string.

🧾 System Information

Home Assistant Version: 2024.7.2 (latest as of July 2, 2025)

Installation Type: Home Assistant OS (Raspberry Pi 4)

MotionBlinds Integration: Default built-in integration

Device MAC: c8:c9:a3:21:8b:29

Device Connection: Wi-Fi (no bridge, direct integration via Connector+)

Device with mac 'c8c9a3218b29' has limit_status '3' that is not yet known, please submit an issue to github.com/starkillerOG/motion-blinds
Device with mac 'c8c9a3218b29' has limit_status '4' that is not yet known, please submit an issue to github.com/starkillerOG/motion-blinds

Additional Notes

The curtain device is listed as a device_tracker in Home Assistant but no cover.xxx entity is created.

This is a first-time setup, using auto-discovery with the correct API key and IP.

Blinds work fine from the Connector+ mobile app.

Position values appear to be returned as strings (e.g. "50"), causing the crash.

The device likely uses a newer firmware or model not yet supported by the library.

@Adoken1111 what is the exact brand and model of your curtain motor?

On which HA version are you?
You stated 2024.7.2, but I hope you mean 2025.7.1 ??

I just update the upstream motionblinds library and created a HA PR to at least ensure that strings are also parsed as integers: home-assistant/core#148265

I tagged it for the HA 2025.7.2 release.
