HomeAssistant and THR320D's intermittent "unknown" values in dashboard

I have a Sonoff THR320D with THS01 sensor, flashed with Tasmota32.bin. I’m able to see values in the dashboard sometimes. At other times, I’m getting “Unknown”. However, even if I see “unknown” values in HomeAssistant, the Tasmota browser page shows valid values.

Is this normal behavior? If not, any ideas what might be causing this? I’m very new to HomeAssistant, so I’m unsure where I should even look to debug this kind of behavior.
