Forced to use this garbage lock and thermostat for our apartment. The nothing works and were sitting here freezing because their "smart" thermostat keeps turning our heat down to 62F. Which makes our bedrooms 55F or lower, with our child who is less than a year old. We tried contacting customer service but were told "no one is available to help". Do yourself a favor and AVOID this app and company at all costs. Huge stepdown from regulat thermostats and locks.
