Serial console reference for ACRouter v2.0 (115200 baud, 8N1). Type help on the device for the
live list. Most of these have a REST equivalent — see the Web API.
7.1 General
Command
Description
help
Show the command list
status
Show router status
reboot
Restart the device
7.2 Router
Command
Description
router-mode <mode>
Set the operating mode — off · auto · eco · offgrid · manual · boost · grid_limit
router-grid-limit <A>
Set the grid current cap (amps) for GRID_LIMIT mode
Driver-direct role (grid·solar·load·voltage·none) — prefer dev-role
rbamp-ct-model <addr_hex> <code>
Set the SCT-013 CT model (preset code) on channel 0
rbamp-address <cur_hex> <new_hex>
Re-address a module (hex or dec)
7.4 DimmerLink (dimmer modules)
Command
Description
dl-status [slot]
Show DimmerLink device status
dl-config <slot> <addr_hex> <role>
Register a DimmerLink in a slot (advanced). Role vocabulary: current_grid·current_solar·current_load·voltage·dimmer·relay (DimmerLink-as-sensor roles)
dl-address <cur_hex> <new_hex>
Re-address a DimmerLink (hex or dec)
Prefer assigning role=dimmer (see Device registry / Commissioning) — the firmware auto-binds the
DimmerLink to a dimmer output. dl-config is the low-level path.
7.5 Device Registry
The recommended way to assign roles — the unified registry, same as the web app's role assignment
(POST /api/modules/role).
Command
Description
dev-list
List all discovered modules (bus, address, family, channels, primary role)
dev-scan [bus]
Re-scan a bus (default 0) and reconcile the registry
dev-role <addr> <channel> <role>
Assign a per-channel role — grid·solar·load·voltage·dimmer·relay·none
dev-identify <bus> <addr>
Identify a device (VERSION-gate protocol)
Use dev-role for normal commissioning. The driver-direct commands (rbamp-config, dl-config,
espnow-config) are low-level alternatives with their own role vocabularies — advanced/diagnostic only.
7.6 ESP-NOW
ESP-NOW is an ESP32-tier feature — these commands apply on ESP32 builds; the ESP32-C2 uses wired
DimmerLink over I2C.
Command
Description
espnow-status
Show ESP-NOW nodes + roles
espnow-config <mac> <role>
Assign a role to a node (grid·solar·load·voltage·none)
espnow-out
List ESP-NOW output nodes (dimmer/relay)
espnow-bind <mac>
Bind an output node to a dimmer (RouterController drives it)
Relays are host-GPIO outputs — functional ids 0–3 (ids 4+ are reserved and not implemented). In the
automatic control they act only in AUTO mode (binary ON/OFF in a priority cascade); ECO / OFFGRID /
MANUAL / BOOST / GRID_LIMIT do not drive relays. Power-aware prioritization is planned for a later phase
— you can always switch a relay manually with relay <id> on|off. The debounce min_on/min_off are
in seconds (default 60 s each).
7.9 Dimmers (output)
Command
Description
dimmer <ID\|all> <0-100>
Set a dimmer output level (I2C dimmer ids start at 4)
Curves: linear (direct angle), rms (for resistive loads). The log curve is a legacy of the
rbDimmer ecosystem for LED loads — not for ACRouter, which drives resistive loads only.
v2.0 dimming is DimmerLink-only; I2C dimmer ids start at 4. If hw-dimmer-status shows legacy
GPIO dimmer slots (ids 0–3), they are retired remnants — not a usable feature.
7.10 Configuration
Command
Description
config-show
Show all config
config-reset
Reset config to defaults
config-gain [значение]
Control gain (10–1000)
config-threshold [значение]
Balance threshold (W, 0–100)
config-manual <0-100>
MANUAL dimmer level
config-ithresh [значение]
Current threshold (A, 0–10)
config-pthresh [значение]
Power threshold (W, 0–100)
7.11 WiFi
Command
Description
wifi-status
Show WiFi status
wifi-scan
Scan for networks
wifi-connect <ssid> [password]
Connect + save credentials
wifi-disconnect
Disconnect from station
wifi-forget
Clear saved credentials
7.12 Web Server
Command
Description
web-status
Show server status & URLs
web-start / web-stop
Start / stop the web server
web-urls
Show all access URLs
web-url set <url> \| clear \| show
Set/clear the external web-app URL (redirect + CORS origin)
7.13 Time (NTP)
Command
Description
time-status
Show NTP sync status
time-sync
Force an NTP sync
7.14 OTA
Command
Description
ota-status
Show OTA status & URLs
ota-check
Check GitHub for updates
ota-update-github
Download + install from GitHub
ota-update-url <url>
Download + install from a custom URL
ota-rollback
Roll back to the previous firmware
ota-info
Show OTA partition info
7.15 MQTT
Command
Description
mqtt-status / mqtt-config
Show MQTT status / configuration
mqtt-broker <url>
Set broker (mqtt://host:port)
mqtt-user <name> · mqtt-pass <pass>
Credentials
mqtt-device-id <id> · mqtt-device-name <n>
Device id / name (HA)
mqtt-interval <ms>
Publish interval (1000–60000)
mqtt-ha-discovery <0\|1>
Enable/disable Home Assistant discovery
mqtt-enable / mqtt-disable
Enable / disable MQTT
mqtt-reconnect / mqtt-publish
Force reconnect / publish
7.16 Diagnostics & Test
Command
Description
sensor-hub
Show the merged sensor-hub state
timing
I2C poll cadence / CPU-time per module
sim-inject <grid\|solar\|load> <A> [V] [W]
Inject a synthetic measurement (Tier-0 test harness). Voltage form: sim-inject voltage <V>. REST equivalent: POST /api/sim/inject
auth-token set <token> \| clear \| show
No-op this release — auth is compiled off, so a token can't be set and write endpoints are open on the LAN
Deprecated (legacy ADC sensing — do not use for measurement):hardware-voltage-*,
hardware-current-* (incl. hardware-current-calibrate-zero). v2.0 sensing is the rbAmp modules
over I2C — use rbamp-* and dev-role instead.
