Control Methods

Web Dashboard

The main Tasmota page (http://device-ip/) shows:

Brightness sliders — one per channel. Move the slider and release to set brightness instantly.

Sensor section — displays per-device status: - Level (%) - Power (ON/OFF) - AC Frequency (Hz) - Firmware version - Temperature and thermal state (if supported by hardware) - Ready status

Serial Console / Tasmota Console

All commands work in: - Consoles > Console (web) - Serial terminal (USB connection)

Brightness commands

plaintext
DimmerLink_Kitchen 75       # Set Kitchen to 75%
DimmerLink_Kitchen 0        # Turn off (sets power OFF)
DimmerLink_Kitchen 100      # Full brightness
# Multi-channel device:
DimmerLink_Lamp1 80         # Channel 1 to 80%
DimmerLink_Lamp2 30         # Channel 2 to 30%

Note: DimmerLink_Kitchen is the same as DimmerLink_Kitchen1 (Tasmota convention: no trailing digit = digit 1).

Dimming curve

plaintext
DimmerLink_KitchenCurve 0     # LINEAR — general purpose
DimmerLink_KitchenCurve 1     # RMS — incandescent/halogen lamps
DimmerLink_KitchenCurve 2     # LOG — LED dimmers (perceptual brightness)
# Multi-channel: specify channel first
DimmerLink_LampCurve 1 2      # Channel 1 → LOG
DimmerLink_LampCurve 2 1      # Channel 2 → RMS

Fade time

plaintext
DimmerLink_KitchenFade 0      # Instant change
DimmerLink_KitchenFade 10     # 1 second transition (10 × 100ms)
DimmerLink_KitchenFade 50     # 5 second transition
DimmerLink_KitchenFade 255    # 25.5 seconds (maximum)

Presets

plaintext
DimmerLinkPreset night        # All devices to 10%
DimmerLinkPreset low          # All devices to 25%
DimmerLinkPreset mid          # All devices to 50%
DimmerLinkPreset high         # All devices to 75%
DimmerLinkPreset full         # All devices to 100%

Presets are defined in dimmerlink.json and can be customized.

Power control

Each DimmerLink device registers a virtual relay in Tasmota:

plaintext
Power6 ON                     # Turn on (restores last brightness)
Power6 OFF                    # Turn off (remembers brightness for next ON)
Power6 TOGGLE                 # Toggle

The relay number depends on how many other relays exist. Check the web UI or use Status 0 to see the relay mapping.

HTTP API

All commands are accessible via HTTP GET:

plaintext
http:///cm?cmnd=DimmerLink_Kitchen 75
http:///cm?cmnd=DimmerLink_KitchenCurve 2
http:///cm?cmnd=DimmerLink_KitchenFade 10
http:///cm?cmnd=DimmerLinkPreset night
http:///cm?cmnd=Power6 ON

URL-encoded format (for use in scripts):

plaintext
http:///cm?cmnd=DimmerLink_Kitchen%2075
http:///cm?cmnd=DimmerLinkPreset%20night

Response format

json
{"DimmerLink_Kitchen1":75}
{"DimmerLink_KitchenCurve":{"Ch":1,"Curve":"LOG"}}
{"DimmerLink_KitchenFade":10}
{"DimmerLinkPreset":"night","Level":10}

MQTT

Sending commands

plaintext
Topic: cmnd//DimmerLink_Kitchen
Payload: 75
Topic: cmnd//DimmerLinkPreset
Payload: night

Receiving responses

plaintext
Topic: stat//RESULT
Payload: {"DimmerLink_Kitchen1":75}

Telemetry (automatic)

Published periodically to tele//SENSOR:

json
{
  "Time": "2026-04-16T08:07:55",
  "ESP32": {"Temperature": 55.0},
  "Kitchen": {
    "Addr": "0x50",
    "Power": "ON",
    "Ready": true,
    "Level": 75
  }
}

Multi-channel telemetry uses Levels array:

json
{
  "Lamp": {
    "Addr": "0x51",
    "Power": "ON",
    "Ready": true,
    "Levels": [80, 30]
  }
}

With temperature sensor (if hardware supports it):

json
{
  "Kitchen": {
    "Addr": "0x50",
    "Power": "ON",
    "Ready": true,
    "Level": 75,
    "Temp": 42,
    "ThermalState": "NORMAL"
  }
}

Status commands

plaintext
Status 8    → includes DimmerLink data in StatusSNS
Status 0    → full device status including relay mapping
