Looks like an ESP8266, with an LCD display and a DHT22 Temp/Humidity sensor... Sound about right?
Have you looked at my HubDuino project? You can build the same thing, with code and drivers already written for Hubitat or SmartThings, for about $15 (no LCD). Obviously, it's nice to have a business writing and maintaining the software for you, which it sounds like pp-Code is doing a great job of.
Take a look at HubDuino. It can do temperature measurement, servo motors, contact sensors, alarm sirens/strobes, etc...
