Follow the recommendations there to determine the cause. An Offline malfunction is a common status meaning the sensor failed supervision checks.
It looks like the sensor reporting this at the moment is on a safe? It’s way more likely to see supervision troubles when a sensor is near a large source of metal. Metal will cause heavy attenuation of RF signals.
To resolve you can try re-orienting the sensor, lifting it off the surface some with a spacer, or use a wired contact that goes into a wireless sensor with a wired input like the DW10.
