I I really struggle with using Rule Machine...I feel like it has a steep learning curve for some reason.
Anyways, I have a PurpleAir Sensor (integrated with HE already) to measure the air quality in our house. When one of the values reaches 45, I want to switch on our ERV (it's already a switch in HE). I then want it to turn off when the value reaches 15. I don't want it to turn off if the Master Bathroom fan is on however. (I have a rule that turns on/off the ERV according to that switch state.
Should I combine these into 1 rule? How would it look? The custom attribute used for the sensor will be aqi10

My house has an Energy Recovery Ventilator (ERV) which brings in fresh air from outdoors. It has a heat exchanger to capture heat (or cool) from the outgoing air. Until recently, it was controlled by a controller in the family room that allowed me to manually adjust what percentage of time it runs. I run it more when there are more people in the house and less when there are fewer - if I remember to adjust it. Sometimes, I forget to bump it up when we have visitors, or forget to set it back when they leave or when the house is empty for days. I never bothered adjusting it for going to work each day.
