You can use attribute copying to take the last known value.

Hi Anton,
Can you example for expression to get last value?

It's not an expression. It's a configuration parameter.

Do you mean config parameter in configuration file on server?

Yes. Check the documentation.

Thank you.

Found this one, I'll try it out, thanks again.

processing.copyAttributes.enable config

Enable copying of missing attributes from last position to the current one. Might be useful if device doesn't send some values in every message.
