We liked the Ecobee EMS-02 stat because:
1. One Login: We could monitor a bunch of them without having to keep track of logins.
2. 1 Year of Data: We could see more than 4 days of data.
3. Auxiliary Board: It also has an auxiliary board where you can plug various dry contacts into (like a ventilating dehumidifier.)

Does anyone know if there is a replacement, or is it just the inexpensive EMS-Si with no auxiliary board?
