While it offers excellent value and energy-saving features, some advanced users might find its customization options less extensive compared to premium models.

However, be aware that this model requires a C-wire for proper operation, which might add complexity to installation in older homes.

However, a significant consideration is that this thermostat requires a C-wire for operation, which might be a hurdle for older homes.
