From f491ac27983b216a2cca8320a4a02ca1a6ed8676 Mon Sep 17 00:00:00 2001 From: Emmanuel Levijarvi Date: Sun, 25 Jan 2026 19:41:39 -0800 Subject: [PATCH 1/7] Use us_customary instead of imperial for Home Assistant consistency Changed all references from 'imperial' to 'us_customary' to align with Home Assistant's official terminology. 'imperial' is maintained as a backward-compatible alias that maps to 'us_customary'. Changes: - set_unit_system() accepts 'us_customary', 'metric', or 'imperial' (deprecated) - get_unit_system() returns 'us_customary' or 'metric' - 'imperial' input automatically maps to 'us_customary' - All docstrings updated to reference 'us_customary' - Type hints support both for backward compatibility Rationale: Home Assistant uses 'us_customary' as the official term for the imperial measurement system. By using the same terminology, we ensure consistency and make integration with HA seamless. Backward Compatibility: - Existing code passing 'imperial' will continue to work - Internally converted to 'us_customary' for consistency - No breaking changes for users --- src/nwp500/api_client.py | 3 ++- src/nwp500/auth.py | 3 ++- src/nwp500/mqtt/client.py | 5 +++-- src/nwp500/mqtt/subscriptions.py | 4 ++-- src/nwp500/unit_system.py | 30 ++++++++++++++++++------------ 5 files changed, 27 insertions(+), 18 deletions(-) diff --git a/src/nwp500/api_client.py b/src/nwp500/api_client.py index dda12f6..b6855a1 100644 --- a/src/nwp500/api_client.py +++ b/src/nwp500/api_client.py @@ -50,7 +50,7 @@ def __init__( auth_client: NavienAuthClient, base_url: str = API_BASE_URL, session: aiohttp.ClientSession | None = None, -
