I am disappointed that you can't permanently set different rooms at different times of the day to control the temperature. For example, the master BR at night and the family room during the day.
Other than that lacking feature, I am happy with the product.

Hi, you can select what sensors you would like to use for each scheduled period from the bottom of the schedule screen. -Joey
Easy to install and use. Remote sensor’s work as advertised - not sure how from a technical standpoint since the thermostat does not control the ventilators.
So far the T9 has been wonderful. It has made the controlling the temperature so much simpler now with the sensor being where we need it and the control in the buildings office.
The only misses I can tell is not having a lock-out, cannot have more than 6 time categories.
It is being used with a 110 year old building with steam heat that we like to warm up in two degree increments per hour prior to events.
Thermostat is nice, and it operates as it should. The wireless sensors are good. App is terrible. It lags-sometimes shows the previous period’s setpoint and room temperature for no reason. There is no easy way to see all temperature sensors and humidity at once. The runtime feature is nice but its always days behind. It would be nice if the app could show history of the room temperatures for the past 24 hrs even.
