Meshtastic may add a buzzer action to help users find nodes

Meshtastic pull request #10755 landed on June 22, 2026, with RCGV1 proposing a small but immediately useful change: “Add Find Node buzzer admin action.” The idea is simple enough to fit in a line item and practical enough to matter the first time a node disappears into a pack, a vehicle, or a cluttered shack. Instead of relying on a screen or a vague last-known location, an admin could make the device sound off and follow the noise.

The request matches a long-running need inside the Meshtastic community. A March 2025 GitHub issue asked for a “Find my” button in the app that would activate the buzzer for a set time even if normal notification sounds were turned off. The use cases were the kind that come up in real life, not in a spec sheet: a node under the couch, in a car, in a tent, or in an office. Another issue framed the same problem more bluntly, noting how useful the feature would be when someone is managing dozens of identical nodes.

The proposal also fits neatly into the platform Meshtastic already has. The External Notification module can drive a buzzer, speaker, LED, or another accessory, and it supports up to three pins independently. Device configuration already includes a GPIO for a PWM buzzer, and the settings are handled through admin messages that send a Config.Device protobuf. In other words, the plumbing is already there for a remote or app-driven locate action to feel native rather than bolted on.

Remote administration itself has been part of Meshtastic for firmware 2.5 and later, where each remote node can store up to three unique Admin Keys. On 2.4.x and earlier, remote admin used a secondary channel named admin with a shared PSK. That matters for a feature like this because the operator may not be standing next to the hardware at all, and the whole point of a buzzer is to recover something hidden from view.

The timing also fits the way Meshtastic deployments actually spread. The project’s configuration tips already point strong nodes toward attics and rooftops, while CLIENT nodes are often treated as favorites in a mesh that stretches across houses, cars, tents and offices. Meshtastic’s firmware page listed v2.7.26.54e0d8d as the latest release on June 23, 2026, as the codebase kept moving. For anyone who has had to dig through gear just to find the right radio, a button that makes a node speak up is the kind of upgrade that saves a morning.
