ecobee introduced the ecobee3 lite smart thermostat HomeKit support and a lower price tag than the standard ecobee3 on Monday. The lower cost model offers most of the features as its not-so-lite brother such as remote access and IFTTT support, alerts, scheduling, and comfort settings. It doesn’t, however, support room activity sensors. The ecobee3 lite is priced at US$169. You can pre-order today and it’ll be available on October 31st.
