Telemetry history decoder

Decode the Base64 reply from MeshCore repeater telemetry commands into a timestamped table. Decoding happens entirely in this browser; the pasted reply is not uploaded or sent anywhere.

Commands to run

Run one of these commands in a local serial CLI or a remote administrator CLI session, then copy the complete reply beginning with > into the decoder.

Data	Newest page	Older-page example	Samples per page
MCU temperature	`get telemetry.temp`	`get telemetry.temp 2`	48 (24 hours)
Battery voltage	`get telemetry.volt`	`get telemetry.volt 3`	48 (24 hours)
GPS position	`get telemetry.gps`	`get telemetry.gps 2`	24 (12 hours)

Page 1 is always the newest. Temperature and voltage support pages 1-7. GPS normally supports pages 1-6; its configured retention can be changed from one through 30 days:

set telemetry.gps 7
get telemetry.gps 1
get telemetry.gps 14

The GPS setter reports the number of days and pages the device could actually allocate. Telemetry history is boot-local, so a freshly rebooted repeater may reply that its history is empty.

Example calls and replies

The buttons above load these synthetic but protocol-valid examples. Real responses have the same > prefix and are auto-detected from payload type 0x11, 0x12, or 0x13.

Reading the table

Timestamps default to UTC. Select Show browser-local time to convert them for display and CSV export.
Temperature preserves exact whole degrees from -50 C through +77 C, plus missing, below-range, and above-range states.
Voltage preserves hundredths of a volt from 1.88 V through 4.40 V, plus missing and out-of-range states.
GPS positions are reconstructed from signed 10-meter differentials. A zero differential after the page origin is inherently ambiguous: it can represent an unchanged fix, movement below the encoded resolution, or no fix. The table labels those rows rather than inventing a coordinate.
A GPS clipping warning means at least one movement exceeded the differential range, so positions after that point can be less accurate.
