Smart Plugs¶

Control your printers with Tasmota-based smart plugs for power monitoring, automation, and energy tracking.

Overview¶

Smart plug integration enables:

• Power control - Turn printers on/off remotely
• Energy monitoring - Track power consumption
• Auto power-on - Start printer before scheduled prints
• Auto power-off - Shut down after cooldown
• Automation - Hands-free print scheduling

Adding a Smart Plug¶

Automatic Discovery¶

The easiest way to add plugs is with automatic discovery:

1. Go to Settings > Smart Plugs
2. Click Add Smart Plug
3. Click Discover Tasmota Devices
4. Wait for the network scan to complete
5. Click on a discovered device to select it
6. Fill in remaining details and Save

Manual Entry¶

If discovery doesn't find your plug:

1. Go to Settings > Smart Plugs
2. Click Add Smart Plug
3. Enter configuration:

1. Click Save
2. Click Test to verify connection

Switchbar Quick Access¶

Add frequently-used plugs to the sidebar for quick access:

1. In Settings > Smart Plugs, expand a plug's settings
2. Enable Show in Switchbar
3. A plug icon appears in the sidebar footer
4. Hover to see status and control all switchbar plugs

The switchbar shows:

• Current power state (ON/OFF)
• Power consumption (if available)
• Quick on/off toggle buttons

Finding Plug IP Address¶

From Tasmota Interface¶

1. Access your plug's web interface
2. Go to Information
3. Note the IP Address

From Router¶

1. Log into your router
2. Find connected devices
3. Locate the plug by name or MAC

Static IP (Recommended)¶

Assign a static IP to prevent changes:

Power Control¶

Manual Control¶

Toggle power from Bambuddy:

1. Go to printer card
2. Click the power icon
3. Select On or Off

Or from Settings > Smart Plugs:

• Click the power toggle for any plug

Power Status¶

Automation¶

Auto Power On¶

Automatically turn on printer before prints:

1. Enable Auto Power On for the plug
2. When a queued print is ready:
3. Bambuddy turns on the plug
4. Waits for printer to boot
5. Starts the print

Auto Power Off¶

Automatically turn off after prints:

1. Enable Auto Power Off for the plug
2. Set Cooldown Temperature (e.g., 40°C)
3. Set Cooldown Time (e.g., 5 minutes)
4. After print completes:
5. Wait for bed to cool below threshold
6. Wait additional cooldown time
7. Turn off the plug

Safety Checks¶

Auto power-off includes safety checks:

• Only triggers after successful prints
• Waits for cooldown
• Checks for queued prints
• Verifies printer is idle

Energy Monitoring¶

Track power consumption:

Real-time Data¶

Per-Print Tracking¶

Enable energy tracking to record:

• Energy per print
• Electricity costs
• Efficiency comparisons

Energy Tracking

Power Dashboard¶

View power statistics:

• Current power draw
• Energy over time
• Cost calculations
• Peak usage

Tasmota Commands¶

Bambuddy uses these Tasmota HTTP commands:

Testing Manually¶

# Turn on
curl "http://192.168.1.100/cm?cmnd=Power%20On"

# Get status
curl "http://192.168.1.100/cm?cmnd=Status%200"

Safety Considerations¶

Don't Cut Power Mid-Print¶

Auto power-off is safe because:

• Only triggers after print completion
• Waits for cooldown
• Checks printer state

Never manually power off during printing!

Surge Protection¶

Consider adding surge protection:

• Protects printer electronics
• Protects smart plug
• Especially important for unstable power

Fire Safety¶

Smart plugs have current limits:

• Most handle 10-15A
• 3D printers typically draw 3-8A
• Check your plug's rating

Troubleshooting¶

Plug Not Responding¶

1. Check plug is powered
2. Verify IP address is correct
3. Ensure plug is on same network
4. Check if Tasmota web interface loads
5. Verify no firewall blocking

Auto Power-Off Not Working¶

1. Check feature is enabled
2. Verify cooldown settings
3. Ensure print completed successfully
4. Check for queued prints (won't power off if more queued)

Power Data Incorrect¶

1. Not all plugs have power monitoring
2. Calibrate in Tasmota: Configuration > Configure Other
3. Check plug specifications
