- Power on your node in the morning. It is not connected to any smartphone or PC via BT/USB/HTTP;
- In the evening, connect to it via BT/USB/HTTP;
- Access all messages received in Primary channel and/or DMs.
Is it possible? How many messages does a node store in it’s internal memory? How to access them via terminal? If node is restarted, are they erased?
I have a Heltec V3. In Meshtatsic CLI there’s --listen option, but it’s about receiving new packages in real time.

And yes, they persist if you restart the node. Not sure what you mean by “terminal”, there are a couple of CLI tools for meshtastic, including a practically complete chat app.
