Exchaging data between nodes

[gio-dot]

Hi, thank you for your project. It would be possible to exchange data between nodes? My goal would be to send data (voltage, temperature, power etc.) from an esphome node to another (to realize a remote display that can work even if homeassistant is down), but it is not clear to me if it is possible and how. If it is already possible, can you please add an example for such use case?
