[Wayback/Archive] From Meh to WOW – With 1 “Tiny” Hack! – YouTube shows an interesting but convoluted solution to solve temperature drift on a cheap Tuya WT410-BH-3A-W thermostat (there are similar models, see below) based on the replacement sensor [Wayback/Archive] WSEN-TIDS Temperature Sensor IC & EV-Kits | Sensors | Würth Elektronik Product Catalog.
