*
* Change Log: shared with ecowitt_gateway.groovy
* lgk add debugging with auto turn off so we can see if it is getting temp because it wont show an update event in hubitat logs if the same as last temp.
* lgk add lastTemperatuer and lastHumidity attributes so we can easily write rules to trigger if the temp or humidity is going up or down.
* I use this to alert when the hot tub will be at max in xx amount of time etc.
*
* lgk add code for capablity Air Quality using aqi
* lgk add srain_piezo and raining = true or false, also capacitorVoltage and firmware versions, stick the raing on the rain device and cap voltate and firmware version on the wind device
