I would think that anything non manual is going to be expensive unless you build it yourself. You'd need multiple temperature probes, some sort of communication between the readings and a datalogger. Using a computer would simplify things, but you'd be doing at least some low level programming, and measuring multiple points without having wires running all over your house means communication, which means power sources and other complications.
If you're not against crunching a little data yourself, just compiling some spreadsheets together, then I'd grab some simple temperature data loggers. Here's a temp only for super cheap:

And here's temp an humidity. Not terribly expensive, but adds up a bit for four. Still, I doubt you'll get much cheaper (providing you can get them in EU for similar price):
