Lilygo Pager is a great choice for running Blackout Comms as your backup grid-down local communication system.
Blackout Comms is an off-grid encrypted messaging and location sharing system that does not use phones, cell service, or internet. Instead it uses non-phone devices, LoRa frequencies, encryption, and mesh techniques to securely communicate, even in a full blackout.
Here I show how to use Lilygo Pager with Blackout Comms. You could have multiple pagers and/or T-Decks, Heltec e290s, T-Beam Supreme, Altware Full Touch, and Altware Mesh Links, in any combination as part of your private mesh cluster.
Blackout Comms allows a delivery to continue for up to 89 mesh hops and up to 24 hours. All direct/mesh messages are asymmetrically encrypted (end-to-end) and digitally signed.
You can even build your own devices using components available at Amazon and other sources.
