Typical errors:

• 🔊 Voice unchanged after being saved to Mi Home → Restart the robot (hold the power button for 10 seconds) or update the app.
• 📱 Mi Home Mod does not display the voice section → Install a version of the app that is not newer than 6.5.410 (new versions block mods).
• 💻 When you are running a firmware error "Invalid package" → Check the checksum (MD5) downloaded.
• 🔇 Castomic sounds are reproduced with distortions → Convert files to 16kHz, 16 bits, mono with Audacity.

If you are using Valetudo and you encounter a 502 Bad Gateway error when downloading sounds, check:

1. Docker is a systemctl status docker.
2. Is there enough memory space (at least 50 MB required)?
3. Does the router block access to the Valetudo cloud (try turning off the firewall)?
