Group chat via mesh network
Organize group chats without internet via MeshCore. Coordinate with family, neighbors or response teams during emergencies in the Netherlands
Why group chat is important
During emergencies, group communication is crucial. You don't want to message everyone individually – you want one message to your whole family, neighborhood or response team. With MeshCore group chat you can do that, completely without internet.
Channels work like WhatsApp groups, but via radio. Everyone on a channel receives your messages. Perfect for organizing help, sharing updates, or coordinating during evacuations.
Types of channels
📻 Public channels
Everyone nearby can read and participate. Ideal for general updates, warnings or community messages. Note: not encrypted.
🔒 Private channels
Only members with the correct key can participate. Perfect for family communication or small response teams. Encrypted for privacy.
🏘️ Neighborhood channels
Channels per neighborhood or street. Coordinate with direct neighbors, share local info, organize help. Grows organically with the network.
🚨 Emergency channels
Special for crisis situations. High priority, no chat – only important announcements. Reserve for real emergencies.

4. Monitor multiple channels
