I have a dozen of those style temperature gauges all over my house. Mine are actually a slightly smaller, square version. You can use Home Assistant to read the Bluetooth temperature and humidity readings from them. They ended up costing maybe $3 each when buying several at a time. Battery tends to last a bit over a year.
