Recommended Configuration Settings
In order to maintain a healthy mesh network, we recommend the following configuration settings for your Meshtastic devices.
These settings are intended to facilitate a stable and reliable mesh network. They are based on the collective experience of the Mountain Mesh community and are subject to change as the mesh grows and evolves.

| Device metrics update interval | 3600 (1 hour) |
Change to 1800 when testing new nodes. |
| Environment metrics update interval | 3600 (1 hour) |
