Thermometer & hygrometer freshness (#83)
If your Govee thermometer readings look "frozen," that's the Govee cloud, not the integration: WiFi sensors (H5179) refresh ~every 10 min, and Bluetooth sensors behind an H5151 gateway (H5075, H5110) batch-upload every 15–60 min. The integration faithfully shows the latest value Govee has — confirmed via diagnostics, and the same limit hits govee2mqtt and homebridge-govee.
What's new:
- "Last Changed" timestamp — each thermometer now exposes a diagnostic timestamp showing when its reading last moved, so you can tell a stale value from a healthy one at a glance.
suggested_display_precisionapplied to temperature/humidity sensors.- README "Thermometers & Sensors" section explaining the cloud cadence and how to get real-time readings: enable Home Assistant's first-party
govee_bleintegration for in-range sensors, or add an ESPHome Bluetooth proxy near remote ones (~2-second updates, no cloud).
Reading ~1.8× too high (e.g. 74 instead of 23)? Your device reports °F via the API — set Temperature unit from Govee API → Fahrenheit in the integration's options.
