Looking for some cheap temp/humidity sensors

For the Xiaomi, Zigbee repeaters are the concern, then. There are only a few known to play well (the ihiyardi repeater/sensor mentioned above, the Ikea Trådfri outlet or USB repeater, or the discontinued non-A variant of the Sylvania outlet, besides some bulbs I'd be suspicious of for other reasons, are the only off-the-shelf solutions that look like they may have ever been readily available in the US; an Xbee, if you have or want one, is also great, and there's another USB sniffer/repeater module that could also work with some effort).
