Exploring MQTT Integration with DateTime Items

Hello fellow MQTT enthusiasts! I’m diving into the world of MQTT and have come across an intriguing challenge that I’d love to discuss with the community.

DateTime Items and MQTT
I’ve been working with DateTime items in my setup and stumbled upon an interesting issue. Specifically, I’m trying to figure out how to reset a DateTime item to NULL via MQTT. I’ve tried several payloads like empty strings, null, NULL, -, and UNDEF, but none seem to work without triggering warnings in the logs.

What’s the Correct Payload?
Does anyone know the correct payload format to reset a DateTime item to NULL? I’m curious if this is even possible or if there’s a workaround.

MQTT and Persistence
While we’re on the topic of MQTT, I’m also exploring how to integrate MQTT with persistence strategies. I’ve set up some basic persistence rules, but I’m not entirely sure if I’m utilizing them correctly. Any tips or best practices would be greatly appreciated!
