Not WF gear but any cheapo Acurite indoor/outdoor sensor with a small indoor display can do this for under 20 bucks or so. Picking a random Amazon listing as an example - (link)
If you want remotely, an ecowitt gw1000 gateway connected to your wifi will do this for 30 bucks but you’d need a phone app or Home Assistant or weewx etc. to cook up a quickie display. Or a sensor on a breadboard connected to a pi or arduino. Not a lot of work to do at all.
