I have remembered you were asking about this same project a couple months ago here: [Copying my Door control status back to my Mysql databse](https://discourse.nodered.org/t/copying-my-door-control-status-back-to-my-mysql-databse/30383)

You also have this thread from earlier today: [How to calculate 2 msg.id coming from 2 pub different topics simulataneously](https://discourse.nodered.org/t/how-to-calculate-2-msg-id-coming-from-2-pub-different-topics-simulataneously/32730)

If you have two separate messages arriving from MQTT nodes and you need to compare them, you need to get both values into a single message. I pointed you at a recipe for doing that here: [How to calculate 2 msg.id coming from 2 pub different topics simulataneously](https://discourse.nodered.org/t/how-to-calculate-2-msg-id-coming-from-2-pub-different-topics-simulataneously/32730/2)

It is not clear if you have tried anything we have suggested. If there is something you are not sure about, please ask - but please read the material we point you at first.
