Yeah, I highly doubt that an IP address and some logs are enough for a warrant. Might be enough for them to go take a look around, but if there's nothing to see or smell, no complaints from the neighbors, nothing in your public trash bins that's suspicious, well...that's about the end of the road for them.

Same goes for helicopter surveillance and thermal imaging, at least in the U.S. - they can't thermally image your house, see 20 1k lights, then get a warrant. Why? Because the Supreme Court has decreed that thermally imaging someone's home *is* a search and thus requires a warrant *before* they do it. And if they have a warrant already, then there's no point in wasting helicopter time or using expensive thermal imagers when they've got bored cops willing to tear homes apart and lotsa cheap squad cars. But I'm sure they do cheat a little, by thermally imaging entire neighborhoods, seeing where the lights are, then snooping around those homes to see if they can find some evidence that *would* allow a warrant. But again, if there's nothing to see, nothing to smell, no complaints from neighbors, no suspicious foot traffic, well...the road ends there, again. (Not to mention, there's nothing at all illegal about buying some 1k lights and having an indoor tropical bonsai garden or some peppers or whatever.)
