Two nasty surprises in Home Assistant's config

This article details a Home Assistant user's experience automating motorized rolling shutters based on temperature and time. The author creates custom binary sensors for 'hot outside' and 'cold outside' using Météo France integration, then sets up automations to close shutters at 6 AM when hot. However, they discover the automation fires one hour late due to a timezone display bug (Paris/+1 instead of +2 during summer). Attempting to fix by overriding the timezone in configuration causes a loss of all UI-set parameters, including temperature unit and access URL. The article highlights pitfalls in Home Assistant's timezone handling and configuration management, relevant to IT/tech automation enthusiasts.
