The DS18B20 (on a Feather Huzzah) seems to miss some rapid changes that the SHT30 (on a D1 mini shield) reports, even though TelePeriod=60 for both. The DS18B20 does seem to report changes within 60s of each other sometimes so I think we’re just seeing duplicate values elided, which I do expect.

The thermostat on the wall near them (which they’ll be replacing) reports 70F, closer to the DS18B20. I have a thermocouple for my Fluke multimeter which I may try to calibrate in ice water and then use to calibrate the temp sensors, though I’m curious if there’s an easier way; or I might not bother since I care more about just setting the climate for room comfort than specific numeric temperatures.

The data path is: Tasmota -> MQTT (Mosquitto) -> HomeAssistant -> InfluxDb. In this case the chart’s just in InfluxDb’s data explorer, though I have some dashboards in Grafana too (which was the motivation for having Influxdb).
