The notification display the topic (as title) and payload. The payload is currently an object (that we joined together) - and not just a number. You need to add a change node to move the msg.payload.temparature to msg.payload.

If you need to save the min and max over restarts then you need to find out about persistable context - a good write up here - [A guide to understanding 'Persistent Context'](https://discourse.nodered.org/t/a-guide-to-understanding-persistent-context/4115)
