I recently saw mention of https://shop.ecowitt.com/products/wn38 which has a disclaimer that I didn't look into further.
*"The WN38 Black Globe Thermometer measures and displays the black globe temperature only, which can be viewed on the LCD screen or through the Ecowitt or WS View Plus app.* *To display WBGT (Wet Bulb Globe Temperature) data in the app, the WN38 must be used together with an Ecowitt outdoor temperature and humidity sensor from either an outdoor array or a WN32(WN31 is not feasible)."* There is a lot of discussion at https://www.wxforum.net/index.php?topic=49316.0 which might be worth a read. Hope this helps. On Wednesday, June 10, 2026 at 10:03:28 AM UTC-7 David Hathaway wrote: > There is a 'wetbulp.py' (note the p) in this group that calculates it as a > xtype_service.
