description: Control IKEA/TP-Link Kasa smart bulbs (set on/off, brightness, and color). Use when you want to programmatically control a local smart bulb by IP on the LAN.

control-ikea-lightbulb

This skill provides a lightweight Python script to control a local smart bulb (supports TP-Link Kasa-compatible bulbs via python-kasa). It is intended for local LAN devices that do not require cloud credentials; control is by IP address.

When to use this skill

  • •When you want to turn a bulb on or off
  • •When you want to set brightness (0-100)
  • •When you want to set color (HSV)
  • •When you have the bulb's local IP and it's accessible from this machine

Contents

  • •scripts/control_kasa_light.py — main runnable script (Python 3.9+)
  • •scripts/light_show.py — small light-show controller for sequences (uses python-kasa). Changes include:
    • •Default white uses a high color temperature (9000K) to make white appear "whiter"; pass --white-temp to override.
    • •Bug fixes: the off-flash between blue→red now ignores transitions to white (saturation==0) to avoid white<->blue ping-pong, and white-temp is only applied to white steps (fixes red being skipped during off-flash). White steps also set brightness even without --double-write.
  • •scripts/run_test_light_show.sh — helper to run light_show via uv

Notes

  • •This repo is set up for uv (no manual environment activation). Dependencies live in pyproject.toml and wrappers prefer uv run. Example: uv run --project ./skills/control-ikea-lightbulb python ./skills/control-ikea-lightbulb/scripts/control_kasa_light.py --ip 192.168.4.69 --on --hsv 0 100 80 --brightness 80
  • •Install uv:
    • •brew install uv (macOS)
    • •pipx install uv (cross-platform)
  • •The provided wrapper script requires uv: ./skills/control-ikea-lightbulb/scripts/run_control_kasa.sh --ip 192.168.4.69 --on --hsv 0 100 80 --brightness 80
  • •The test helper also prefers uv: ./skills/control-ikea-lightbulb/scripts/run_test_light_show.sh --ip 192.168.4.69 --duration 6 --transition 1 --off-flash --verbose
  • •If your device is actually an IKEA TRADFRI device (not Kasa), this script is a starting point; tell me and I will add TRADFRI support.
  • •No cloud credentials are required; control happens over LAN to the device's IP.

Quick start

  1. •Install uv (macOS): brew install uv
  2. •Turn the bulb on (replace the IP): ./skills/control-ikea-lightbulb/scripts/run_control_kasa.sh --ip 192.168.4.69 --on
  3. •Set color and brightness: ./skills/control-ikea-lightbulb/scripts/run_control_kasa.sh --ip 192.168.4.69 --hsv 0 100 80 --brightness 80

Git note

  • •No local environment artifacts are tracked; use uv.

Note about Python requirements and recent change

  • •The skill previously declared python-kasa>=0.13.0 which caused dependency resolution failures on this machine. To make the skill runnable locally the project's pyproject.toml was adjusted to:
    • •requires-python = ">=3.11, <4.0"
    • •python-kasa>=0.10.2
  • •This allows the resolver to pick a compatible python-kasa on machines with Python 3.11+. If you prefer a different constraint (or want me to revert this change), tell me and I will update the pyproject.toml and README accordingly.
