### 2023-02-22 {#2023-02-22}

**Firmware 17.4.0**: This update resolves an issue where the extension module (Zigbee) could lose connection to the main module, causing the lock to register no Zigbee module.
It also fixes a problem where the lock could lose connection to the Zigbee network, as well as an issue that caused increased battery drain when the Zigbee network connection was lost.
