Not sure if @muxa is around any more, but apparently we are supposed to be reporting humidity as an integer in Hubitat, not a decimal. As the system is assuming integer, it will break things like simple automation rules and basic rules if it reports as a decimal.
If you are still updating this driver, may want to make that change when there is time.
See this thread.
I changed my copy of the driver to this to make it "compliant". Basically just added a new int humidityInt, and then used that in the report. Sloppy way to do it, but it worked and I didn't feel like modifying it any more than that.
// Calculate humidity with 0.1 precision
private parseHumidity(valueHex) {
float humidity = Integer.parseInt(valueHex,16)/100
displayDebugLog("Raw reported humidity = ${humidity}%")
humidity = humidityOffset ? (humidity + humidityOffset) : humidity
humidity = humidity.round(1)
int humidityInt = Math.round(humidity)
return [
name: 'humidity',
value: humidityInt,
unit: "%",
descriptionText: "Humidity is ${humidityInt}%",
]
}
