I think the OP said they were looking for temperature and humidity
indoors, so I don't think an outdoor weather station quite fits the
bill as well as being an order of magnitude too expensive! :(
There are quite a few battery-powered T+H sensors with wi-fi, but I'm
not up to date with which ones can be intercepted to provide data
directly rather than uploading to a 'cloud'.
Certainly some emonTH plus an emonBase from
https://shop.openenergymonitor.com/ would do the job, but I expect
there are other alternatives
