#LongPost Last weekend, I spent some time figuring out how I could control one of my storage heaters via Bluetooth and #HomeAssistant. It was relatively straightforward, adjusting settings, seeing what changes happened using BLE Scanner, and then using ESP32-BLE2MQTT to handle the integration. Sorted.
I'd also noticed that the OEM app synced the heater's clock whenever it connected. "Great!", I thought, and set up an automation to do that automatically each night at midnight. Everything looked great.
Except it wasn't. During the week I'd noticed the room getting colder and colder and that the heater wasn't taking a charge. Yesterday, looking through the heater diagnostics, I saw it hadn't recorded any usage data for the week, so updating the clock at midnight was preventing it from charging. Changed that automation and - hurrah - last night gave us heat! Creda storage heater Home Assistant = win!
