Thermostat and thermometer are 2 different things. Thermostat controls temps and thermometers take temps. If you don't have a thermostat you need to unplug uth until you have one. If you do have a thermostat the probe should be sandwiched between the uth and bottom of tank. Then you need to adjust the thermostat until your thermometer reads no higher than 94 under the substrate (bedding) over the uth. Being that you said you can't keep an eye on it and you unplug it at night I'm assuming you don't have a thermostat bc with a thermostat it keeps the temp consistent so you don't need to watch it. By running the uth unregulated your putting the snake in danger.
