Last revision: October 1, 2026

Before you start

Secure the power supply before any update.

Never cut the power during the OTA update.

After the update, the controller starts in AP mode only. Reconnect to home Wi-Fi afterwards from Tools → WiFi / LAN Setup.

Network name: documentation for earlier versions may show CP-Controller-XXXX. Firmware 2.0 documented here uses CP-Control_XXXXXX. Always use the SSID actually displayed by your controller.
