Tasmota Motorized Roller Blinds

Tasmota Motorized Roller Blinds

Automate your existing roller blinds or shutters with Tasmota firmware. Using a dual-relay device like the Sonoff Dual R3 or Shelly Plus 2PM, you get full position control, MQTT integration, and Home Assistant cover entity support.

Why This Project

• Affordable — $15-25 for the controller
• Works with existing blinds — no need to replace your window coverings
• Position tracking — 0-100% with calibration
• Multiple motor types — AC motors, DC motors, or stepper motors
• Physical buttons retained — wall switches still work alongside smart control
• Home Assistant native — appears as a cover entity

Option 1: AC Motor with Sonoff Dual R3 (Most Common)

Components

Component	Purpose	Est. Cost
Sonoff Dual R3	Dual relay controller with interlock	$15
AC tubular motor (e.g., A-OK AM25)	Drives the blind roller	$40-70
2× momentary wall switches	Physical up/down control	$5

Wiring

Mains L ──→ Dual R3 Common
Dual R3 Relay 1 ──→ Motor UP wire (typically brown)
Dual R3 Relay 2 ──→ Motor DOWN wire (typically black)
Motor Common ──→ Mains N (typically blue)
Wall Switch UP ──→ S1 input
Wall Switch DOWN ──→ S2 input

Tasmota Configuration

# Enable shutter mode
SetOption80 1

# Assign relay pair to shutter
ShutterRelay1 1

# Set travel times (measure your blind)
ShutterOpenDuration1 15
ShutterCloseDuration1 15

# Enable interlock (prevent both relays ON simultaneously)
Interlock 1,2
Interlock ON

# Button rules for wall switches
Rule1 on Switch1#state=1 do ShutterOpen1 endon on Switch2#state=1 do ShutterClose1 endon
Rule1 1

Option 2: Shelly Plus 2PM (with Power Monitoring)

The Shelly Plus 2PM adds power monitoring, which enables auto-calibration — Tasmota can detect when the motor stops drawing current (blind fully open/closed) for precise position tracking.

Tasmota Configuration

Same as above, but with power-based calibration:

# Enable shutter mode
SetOption80 1
ShutterRelay1 1

# Calibrate using the Google Sheets spreadsheet
# (link in Tasmota docs)
ShutterCalibration1 30 50 70 90 100

Option 3: Stepper Motor with Wemos D1 Mini

For IKEA TUPPLUR or similar blinds, use a 28BYJ-48 stepper motor:

Components

Component	Purpose	Est. Cost
Wemos D1 Mini	WiFi controller	$3
28BYJ-48 stepper motor	Drives the blind	$2
ULN2003 driver board	Stepper motor driver	$1
3D-printed bracket	Mounts motor to blind	Free

Wiring

IN1        →   GPIO14 (D5)
IN2        →   GPIO12 (D6)
IN3        →   GPIO13 (D7)
IN4        →   GPIO15 (D8)
5V         →   5V
GND        →   GND

Home Assistant Integration

Tasmota shutters auto-discover in Home Assistant as cover entities:

# Manual MQTT cover config (if auto-discovery is disabled)
mqtt:
  cover:
    - name: "Living Room Blinds"
      command_topic: "cmnd/tasmota_blind/ShutterPosition1"
      position_topic: "stat/tasmota_blind/SHUTTER1"
      set_position_topic: "cmnd/tasmota_blind/ShutterPosition1"
      payload_open: "0"
      payload_close: "100"

MQTT Commands

# Open fully
cmnd/topic/ShutterOpen1

# Close fully
cmnd/topic/ShutterClose1

# Set to 50% position
cmnd/topic/ShutterPosition1 50

# Stop
cmnd/topic/ShutterStop1

Compatible Devices

• Sonoff Dual R3 — best value, power monitoring, ESP32-based
• Shelly Plus 2PM — premium option with power-based calibration
• Wemos D1 Mini + ULN2003 — for stepper motor builds
• Sonoff Dual R3 Lite — budget option without power monitoring
