I use the zilla digital thermo/hygro with probes for each, it works great, but I'd suggest the temp probe be used for ambient temps as opposed to basking spots.
I had this problem recently, except it was the neighbor and not me, and they actually WERE dealers squating in a vacant house. And I don't even live in a bad neighborhood.
I'm not going to lie, I barely slept the night before I got Hawkeye. I fell asleep at like 1:30 am and popped up at 5:00am without an alarm and sat around for about four and a half hours watching the clock. lol
