What I would do, is move your thermostat probes to under the enclosure between the mat and the bottom of the enclosure as shown in the thread I linked you to. Then get yourself a temp gun like the one below to spot check your temps. You can leave your thermometer probes on the inside but just understand that they could get moved or get wet, so I would not use those as a fullproof way of ensuring your temps are where they need to be. You do need to check your temps at the bottom of the enclosure not on top of the substrate just to be clear. Your snake will move substrate and if the surface of the enclosure is too hot it can burn your snake.
In my enclosures that I still use heat mats in I move the substrate and take the temp with that thermometer linked below. I do this usually once a day when I do my enclosure checks.I don't use any probes at ground level where my animals can move them.

Edit: Just to be clear you don't have to use THIS thermometer, it's just what I use. Also I responded before I saw your reply about looking at the other link so you can ignore that part lol.
