Add Honeywell String Lights integration by balloob · Pull Request #168450 · home-assistant/core

Breaking change

Proposed change

Add a new honeywell_string_lights integration that drives a Honeywell String Lights set via the radio_frequency entity platform. All protocol details (frequency, modulation, timings, repeat count) are provided by the rf-protocols library — this integration contains no hard-coded RF constants.

This PR relies on #168447 — the radio_frequency entity platform. This PR is currently stacked on top of that branch.

Opened as a draft until the parent PR lands.

I have reviewed two other open pull requests in this repository.

Replace the placeholder garage-door example with adapted snippets from home-assistant/core#168450, which shows the real config-flow filtering by a sample command's frequency/modulation and the real send-command path via rf_protocols.get_codes.

Hmm, I am wondering if there's something better describing what a transmitter is

I don't think ruff trips over this

The fixture itself is not used, as we reference to the entity by entity ID. Marks like usefixture cannot be applied to other fixtures.

joostlek · 2026-04-24T13:10:51Z

Oh and are there more honeywell lights that support this? Or just string lights?

balloob · 2026-04-24T13:33:30Z

This is just their string lights as far as Keith and I could tell.

+    assert command.context is context


Compare the expected RF command by value (or by key attributes) instead of using is, since a separate COMMANDS.load_command(...) call is not guaranteed to return the same object instance.
