No, we do not support cellular backup.
A cellular backup feature would only be useful if your home has an Internet outage during a home intrusion. As it is rare (both incidents would have to happen at the same time) it would result in increased monthly costs. Wyze Home Monitoring does not have cellular backup.
Although we don’t support cellular backup, the Sense Hub has a battery backup in the case of a power outage. If your internet connection drops, Wyze Home Monitoring will still work locally. Your sensors will continue to work and send you notifications.
If there is a power outage, emergency services will not be contacted, and the Siren and Emergency Button will not work.
