temp monitor for lights

[Samw]

Thanks. Yes, it will have to be able to take in 2 temperatures. I would set it with maybe 2 or 3 degree difference. Something like: turn off when temp reaches over 30C, and turn on when it reaches below 28C. Also, I will plug it on a timer so that the lights don't turn on between midnight and 7am since the lights might prevent me from sleeping.
