I was wondering if there was such a thing as a humidty thermostat, like if the tank gets below 50% then it kicks the humidifier on. Is there a product like this?

I am trying to get everything so i don't have to constantly mess with settings. I want the temp to regulate itself(thermostat) and i would love for the humidity to be able to do the same, this way all i have to do is fill the water in the huimidifier now and then and spend the rest of the time enjoying my BP. is there machine to clean the cage for me too :lol: .

Oh and rather then making another post out of this i was talking to my vet ant he suggested that when i clean the cage that i use a bleach mixture and clean the whole cage and all the things(climbs,hide ect) in it as well. i had a few concerns with this, first is that if i use the bleach mixture that it will take the color out of the things like her hide box and such that were made to have the wood finish. And more importantly is this really ok for the snake? Granted i would rinse it with fresh water after give it the once over with bleach but it just seem dangerous to use such a serious chemical on a reptile cage. What do some of you guys use to when it comes time for a full cleaning of cages??
