The other recommendations are good, but please please double check your tstat wiring and/or HVAC system to ensure they are compatible. One of the few stats that work with my system without shenanigans is the Honeywell T10 Pro (which also worked out of the box with HA). This required me to rewire the control run to use it, and is not something I would recommend for people who aren't prepared to cook the control board on their furnace if they do an oopsie or regularly read electrical diagrams.
