pyscript for homeassistant to resync local keys from private tuya api

This repository includes

• A script print-local-keys.py to print out local keys for your Ledvance devices (They must be already registered in the Ledvance app) which can be used in the LocalTuya integration for Home Assistant
• Setup via Pyscript Integration to automatically resync local keys

Replace the placeholders in print-local-keys.py and run the script:

pip install pycryptodome
python print-local-keys.py

(Python 3)

If you have many devices and reset them sometimes by accident like me, you can create a service for resyncing the local keys. (New local keys are genereated if you reset/re-register your devices).

• Pyscript Integration
• Set allow_all_imports and hass_is_global to true. (Described here)
• Ledvance account with devices configured

• Replace placeholders in pyscript\sync_tuya_keys.py with your Ledvance account credentials.
• Copy pyscript_modules and pyscript to your Home Assistant config directory.
• In your Home Assistant dashboard should be now under Developer tools --> Services a service called Pyscript Python scripting: synctuyakeys that you can call. (You may have to restart before)
• (If you want Log output, you need to change the log level to INFO or use jupyter)
