Released on March 24, 2026, MeshOS 0.4.1 focuses on giving users fine-grained control over telemetry — the sensor and location data that devices exchange across the mesh network. Whether you're running a remote weather station or just want to know a contact's battery level, this release has something useful.
Configuring Telemetry Responses
A new telemetry settings screen lets you define how your device responds when another node requests data. Three modes are available: Base (battery and device info), Location (GPS coordinates), and Environment (temperature, humidity, pressure, and similar sensor readings). You choose what your device shares — and what it keeps to itself.
Per-Contact Telemetry Permissions
When operating in "From Specific Contacts" mode, you can now grant or deny telemetry access on a contact-by-contact basis. This is handy in mixed networks where some participants should have access to your sensor data and others shouldn't. Permissions are managed directly from the contact detail view.
Requesting and Decoding Telemetry
You can now actively request telemetry from any contact in your list. Incoming data is decoded using Cayenne LPP — a compact, widely-used encoding format for IoT sensor payloads — and displayed in a structured breakdown covering battery voltage, temperature, humidity, atmospheric pressure, GPS position, and more. A refresh button lets you re-request the latest data without closing the dialog.
Telemetry Map View
When a contact's telemetry includes GPS data, it's now plotted directly on an embedded map within the app. This gives you an at-a-glance visual of where your contacts are located, with no need to copy coordinates into a separate mapping tool.
In-App Update Checker
MeshOS now checks for new releases automatically on startup. You can also trigger a manual check at any time via Settings → Version. This ensures you're always aware of the latest firmware and app updates relevant to your setup.
