72-Hour Texas Freeze Key Finding

During the extended freeze, neighbors with battery-backed mesh systems could coordinate help, share resources, and maintain family communication while others were completely isolated. Local redundancy beats cloud dependency every time.

Frequently Asked Questions

Smart thermostats help conserve power during outages, battery-powered security cameras provide monitoring, and smart doorbells let you screen visitors remotely. Focus on devices that work on battery backup or low power.
Use a UPS battery backup for your modem/router, consider cellular hotspots as backup, and invest in mesh systems with battery backup. Starlink with power backup provides internet when landlines fail.
Layered approach: cell phones with external batteries, two-way radios for local communication, weather radio for alerts, and satellite communicators for remote areas. Don't rely on just one method.
Some smart devices work locally (Z-Wave, Zigbee hubs), but most cloud-dependent devices stop functioning. Choose systems with local processing capabilities for critical functions during internet outages.
Mesh networks provide better coverage and redundancy. If one node fails, others continue working. Essential for large homes where communication and internet access are critical during emergencies.
