Fan blower CFM controlled by humidity/heat sensors
Is there an easy way to control an in-line fan blower CFM when humidity is too high or temperature is too low?
Do you have any modules in particular to recommend?
I am trying to use a mini split heat pump to heat more rooms in a house by adding a few ducts back and forth each rooms.

It sounds like you want a thermostatically controlled supply duct. Those are common items for 4" ducts and up. They are sold for 120 volt dampers and for 24 v dampers. Here a sample 24 v unit that includes the supply transformer.

There are many designs and motors to automate a damper. This design I presented does not require a controller, but does require a wall t-stat purchased separately.
Do not try to control the damper with both the temperature and the humidity. Temperature is usually what drives the primary damper process.

No. Those wireless applications do not support dampers and blowers. and it would not prevent you from having to hardwire your power circuits to the devices. A damper and blower both require a power source and that cannot be done wirelessly.

For sure they need power locally but it would have been nice to remote control them from a wall thermostat unit that runs on battery instead of passing wires in the wall.
Not sure why but on amazon.ca those damper are really pricy compared to amazon.com.
