We were informed by Silicon Labs that 700/800 series controllers have a hardware watchdog that can reset the controller when it becomes unresponsive. This feature is now enabled by default in Z-Wave JS and should prevent the controller from hanging indefinitely. In case this causes new issues, the feature can be disabled by setting the environment variable `ZWAVEJS_DISABLE_WATCHDOG` to any non-empty value, or by setting the driver option `features.watchdog` to `false`. Please let us know if this actually helps or not. ### Features * Enable hardware watchdog on 700/800 series controllers (#6954) * Add method to query supported RF regions (#6957) * Add notification variable for Door/Window tilt state (#6958) ### Bugfixes * Fixed an issue where value metadata for unknown notification events with known notification types would only be created if the CC version was exactly 2 (#6959)

I was told that Z/IP Gateway enables the hardware watchdog on 700/800 series controllers. Unlike on 500 series, we don't have to feed it ourselves. This should help with the lockup issue, as the controller is automatically restarted when it fails to feed the watchdog.
This feature is enabled by default, unless the
ZWAVEJS_DISABLE_WATCHDOGenv variable is set, or thefeatures.watchdogdriver option is set tofalse.
