Hi all, I built a Homey app that lets you run Python code directly from Advanced Flows. Three flow cards: Run Script — Python inline in the card, sandboxed (no network, no filesystem). Good for logic and calculations. Output: return\_value and error flow tokens. Run Script with Packages — full Python with pip packages. Install requests, numpy, anything. Packages are cached in a virtual environment. Full Homey API access. Run Named Script — save scripts in the built-in IDE, call them by name from any flow. Sandbox mode and venv configured in the IDE, not the card. * * * From non-sandboxed scripts (Run Script with Packages, Run Named Script): ``` # Read a logic variable value = await homey.logic.get_variable("temperature") # Read or control a device capability state = await homey.devices.get_capability(device_id, "onoff") await homey.devices.set_capability(device_id, "dim", 0.5) # Trigger a flow (add the "Flow triggered from Python" trigger card to that flow first) await homey.flow.trigger("my-tag") return "done" ``` Note: homey.logic.set\_variable() is not supported — Homey restricts logic variable writes to the HomeyScript app only. Note: homey.logic, homey.devices, and homey.flow are NOT available in the sandboxed “Run Script” card — they raise RuntimeError. Use return to pass values to the flow. * * * Example — fetch live weather (Run Script with Packages, venv with requests installed): ``` import requests r = requests.get("https://api.open-meteo.com/v1/forecast?latitude=52.37&longitude=4.90¤t=temperature_2m") return r.json()["current"]["temperature_2m"] ``` The return value becomes the return\_value flow token. If the script raises an exception, the error flow token is set automatically. * * * IDE — settings page with Monaco editor (same as VS Code), Python syntax highlighting, run directly from the IDE, manage virtual environments. Install: Python Script | Homey Source: [GitHub - jaccoh/homey-pythonscript: A Homey app to execute Python script in cards · GitHub](https://github.com/jaccoh/homey-pythonscript) Requires Homey Pro (local) or SHS v13.0.0+. Bugs and PRs welcome. * * * Changelog v0.4.0 - Fixed: scripts that take longer than ~10s (e.g. controlling a slow-moving device) always returned an empty return\_value in the IDE, even though the script itself succeeded. Homey’s Settings-page client enforces a hard, non-configurable ~10s request timeout — the IDE now kicks off the script as a background job and polls for the result instead of waiting on one request. - Fixed: missing timeout arg on the Run Named Script card - Added: timeout field to the IDE’s script tester v0.3.2 - Fixed: new script name now appears in dropdown immediately after creating, without needing to save first v0.3.1 - App Store compliance: plain text readme, new icon, real screenshot v0.3.0 - error flow token now declared on all cards — use it in subsequent flow cards - Sandboxed card: homey.logic/devices/flow now raise a clear error instead of silently doing nothing (they were never supported in sandbox mode) - Fixed: script syntax errors in non-sandboxed cards now surface as an error instead of silently succeeding with an empty return value - Fixed: concurrent bridge calls no longer race on the IPC channel - Removed dead code (sandbox.py, unused HomeyContext internals) v0.2.3 - homey.flow.trigger(“tag”) working via trigger card mechanism - homey.logic.get\_variable() — read logic variables from Python - homey.devices.get\_capability() / set\_capability() — read and control devices - Fixed: sandboxed card could not be killed on timeout (now uses subprocess) - Fixed: IPC pump robustness (KeyError, BrokenPipe, subprocess leak) v0.2.2 - Initial release ---

Did you even run your own app? Seems your Claude has completely hallucinated stuff. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/9/b937b0bb0ac66617f7d1cbd0a456b1cbc235651d.png) ---

Ofcourse I did, I’m running it as I speak to open and close curtains via Python. I’ll have a look if I can reproduce this. ---

by the way, I clearly stated its a very very early version… so… cut me some slack.. it really works ---
