Control Ikea Lightbulb

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 Install uv (macOS): brew install uv Turn the bulb on (replace the IP): ./skills/control-ikea-lightbulb/scripts/run_control_kasa.sh --ip 192.168.4.69 --on 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.
