2021 Update, LTE Backup

Since the previous posts on this topic are ~3 years old, I thought I’d put this up for current advice and comments. Based on reading of those posts, here is the plan for the Konnected kit I just ordered. For those with experience, does it look like the best way to accomplish these?

  1. Failover LTE connection for security-related items in the event of cable internet failure.

  2. Keep high bandwidth items that are not security-related separate from LTE backup to minimize usage.

  3. Utilize ethernet for security-related devices so the core system is not wifi dependent.
