Repeater Web API¶

This page documents the local HTTPS API exposed by EastMesh *_repeater_mqtt builds that support the web panel.

It is intended for:

• lightweight automation on your local network
• dashboards or scripts that need current repeater status
• remote CLI access through the same authenticated path used by the web panel

This is not a cloud API and not a separate backend service. The repeater firmware serves it directly.

Scope And Availability¶

The API is available only when:

• you are running a supported *_repeater_mqtt firmware build
• the repeater web panel is enabled and running
• you can reach the repeater over the local network
• you have authenticated with the repeater admin password

The API is intended for trusted local-network administration. Do not expose it directly to the public internet.

Base URL¶

Use the repeater's local HTTPS address:

https://<repeater-ip>/

Example:

https://192.168.1.123/

Authentication¶

The API uses the same admin password as the repeater CLI and web panel.

1. POST the password to /login
2. store the returned session token
3. send that token in the X-Auth-Token header on later requests

Example:

TOKEN=$(curl -sk -X POST https://<repeater-ip>/login --data '<admin-password>')

Use the token:

curl -sk https://<repeater-ip>/api/stats -H "X-Auth-Token: $TOKEN"

Notes:

• the repeater uses a self-signed certificate, so most tools will need -k or equivalent
• if the session expires or is locked, requests return 401 Unauthorized
• logging in again gives you a fresh token

Performance Guidance¶

The API runs on the repeater itself, so polling frequency matters.

If the repeater is also running two MQTT connections, avoid frequent API polling. The current EastMesh usage pattern is:

• 60 second polling for stats
• on-demand requests for everything else

That is the recommended baseline if you want to avoid overloading the board. Keep the request rate low, avoid bursty polling, and prefer manual refresh or event-triggered reads for heavier operations.

Recommended practice:

• poll /api/stats no more than once per minute
• avoid scraping multiple endpoints in parallel
• use on-demand calls for configuration reads and CLI actions
• close out your session when you are finished and stop polling when not actively using the data

Endpoints¶

POST /login¶

Authenticate with the repeater admin password.

Request body:

<admin-password>

Response:

• plain-text session token on success
• 401 on bad password

Example:

curl -sk -X POST https://<repeater-ip>/login --data '<admin-password>'

POST /api/command¶

Run a repeater CLI command remotely.

Headers:

X-Auth-Token: <token>

Request body:

get wifi.status

Response:

• plain-text CLI output
• OK if a command succeeds without returning text

Example:

curl -sk https://<repeater-ip>/api/command \
  -H "X-Auth-Token: $TOKEN" \
  --data 'get wifi.status'

GET /api/stats¶

Fetch the current summary payload used by the dedicated /stats page.

Headers:

X-Auth-Token: <token>

Example:

curl -sk https://<repeater-ip>/api/stats \
  -H "X-Auth-Token: $TOKEN"

Notes:

• this summary view is also what the repo's web panel requests first before loading trend series
• if web.stats is disabled, the endpoint returns 503 Service Unavailable
• supported boards may also include an optional sensors object in the summary payload for current GPS and environmental telemetry
• the core object includes raw battery_mv, board-reported battery_pct when available, a UI-ready battery_display_pct, and board-specific battery_min_mv / battery_max_mv range hints used by /stats when the board does not expose its own battery percentage

GET /api/stats?series=<name>¶

Fetch one trend series.

Supported series:

• battery
• memory
• signal
• noise_floor
• packets
• voltage
• sensor_temp
• humidity
• pressure
• pressure_altitude
• mcu_temp
• gps_altitude
• gps_satellites

Example:

curl -sk "https://<repeater-ip>/api/stats?series=memory" \
  -H "X-Auth-Token: $TOKEN"

Notes:

• use ?series=battery, not just ?series
• the built-in web panel loads these series sequentially rather than all at once to keep board memory pressure lower
• environment series are included only when the board reports those readings; if a series has no captured points yet, it returns an empty points array and current:null

GET /api/stats?view=legacy¶

Fetch the older bundle-style stats payload.

Example:

curl -sk "https://<repeater-ip>/api/stats?view=legacy" \
  -H "X-Auth-Token: $TOKEN"

This exists for compatibility and troubleshooting. For new integrations, prefer the summary endpoint plus specific series requests.

Common Use Cases¶

1. Remote CLI Access¶

/api/command is the most flexible endpoint. It lets you run the same CLI commands accepted by the repeater.

Examples:

• get wifi.status
• get mqtt.status
• get web.status
• get web.stats.status
• get repeat
• get radio

This is useful for:

• remote diagnostics from a laptop or phone
• simple scripts that collect operational state
• admin tools that want to reuse existing CLI behavior instead of adding new firmware endpoints

Example:

curl -sk https://<repeater-ip>/api/command \
  -H "X-Auth-Token: $TOKEN" \
  --data 'get mqtt.status'

2. Build A Lightweight Status Dashboard¶

Use /api/stats for summary information and one series call at a time for trend lines.

Recommended pattern:

1. fetch /api/stats
2. render current service state and summary fields
3. fetch one trend series only when needed
4. refresh at 60 second intervals, or slower if the repeater is busy

This is the same basic pattern used by the built-in /stats page.

3. Reuse The API For Quick Health Checks¶

Because /api/command returns CLI output directly, it works well for small operational checks in scripts or home-lab monitoring.

Examples:

• confirm the repeater still has Wi-Fi
• check MQTT broker connection state
• verify that the web panel is enabled before attempting stats reads
• confirm current radio settings before applying changes

Example:

curl -sk https://<repeater-ip>/api/command \
  -H "X-Auth-Token: $TOKEN" \
  --data 'get web.status'

4. Remote Admin Actions¶

The web panel also uses /api/command for operator actions, not just read-only queries.

Examples:

• advert
• reboot
• start ota
• time <epoch>
• time.force <epoch>

These are powerful commands. Treat them the same way you would treat direct serial CLI access.

Example:

curl -sk https://<repeater-ip>/api/command \
  -H "X-Auth-Token: $TOKEN" \
  --data 'advert'

5. Remote Configuration Helpers¶

The web panel saves settings by generating CLI commands and sending them through /api/command.

That means your own tools can do the same for EastMesh-specific settings such as:

• repeater identity fields
• owner info
• MQTT broker toggles
• EastMesh MQTT owner metadata
• radio settings supported by the repeater CLI

This is a practical way to automate setup while preserving existing CLI semantics.

Example Script¶

This shell example logs in, fetches summary stats, fetches one trend series, and runs a CLI command:

#!/usr/bin/env bash
set -euo pipefail

BASE_URL="https://192.168.1.123"
PASSWORD="your-admin-password"

TOKEN=$(curl -sk -X POST "$BASE_URL/login" --data "$PASSWORD")

echo "Summary:"
curl -sk "$BASE_URL/api/stats" \
  -H "X-Auth-Token: $TOKEN"

echo
echo "Memory trend:"
curl -sk "$BASE_URL/api/stats?series=memory" \
  -H "X-Auth-Token: $TOKEN"

echo
echo "MQTT status:"
curl -sk "$BASE_URL/api/command" \
  -H "X-Auth-Token: $TOKEN" \
  --data 'get mqtt.status'

Error Cases¶

Common responses:

• 401 Unauthorized: missing or expired token
• 503 Service Unavailable: stats are disabled
• 404 No stats data: requested stats payload could not be built
• 400 Bad request: malformed login or command request body

If stats requests fail:

1. confirm the web panel is enabled
2. confirm web.stats is enabled
3. confirm the session token is still valid
4. reduce polling frequency if the board is under memory pressure

Practical Recommendations¶

• prefer /api/command when you need exact CLI parity
• prefer /api/stats for dashboards and trend views
• keep polling conservative, especially on repeaters with two active MQTT connections
• if you are finished with troubleshooting, consider disabling the web panel with set web off to maximize heap headroom on constrained boards
