CAN I INSTALL A FAN CONTROL FOR A FAN WITH REMOTE DRIVER

This is where I am totally lost, as I know nothing about relays, etc. So, my current thought is to put some sort of relay(?) on the furnace system (or Thermostat, which apparently talks to an Equipment Interface Module sitting next to the furnace), to monitor when the blower motor is on or off. So, monitoring for change of Idle wonвЂ™t work. I only get an event posted IF I reset the setpoint to make the air (or heating) come on, not when it comes on/off by itself to maintain the setpoint. SmartThings always reports the status as Idle. BUT, if I simply leave the thermostat at a given setpoint, and it comes on and off to maintain that setpoint, NO event is ever posted to Smartthings when the air comes off or on. The problem is, if I manually reset the cooling (or heating) setpoint, SmartThings receives a ThermostatOperatingMode event such as вЂњCooling to 72 FвЂќ, and my piston is triggered. SmartThings controls it just fine, but when I try to use CoRE to monitor the ThermostatOperatingMode to determine when it changes from Idle, I ran into issues.

I have a Honewell THX9421R5021WW thermostat (Redlink connection), so am using the Honeywell 9000 Thermostat device driver to talk to it (IвЂ™ve tried also the Honeywell VisionPro Thermostat). I was hoping to control this fan via SmartThings, by changing the existing variable speed knob switch with a controllable relay (IвЂ™m thinking the FS20Z-1 ?), and then monitoring my HVAC system for when the fan motor goes out of Idle (either heating or cooling). I just want to automate the turning on/off of it. ItвЂ™s purpose was to provide extra airflow to the downstairs storage area, which works fine if/when itвЂ™s on. The problem is I have to manually turn on the fan when I want to have it come on, and then leave it running (or run downstairs every time the HVAC comes on and off). I have a home that has an installed inline Duct Fan (Fantech FG6 - ), that is controlled manually via a Variable speed switch ( ). Very new to SmartThings, so hoping someone can guide me on a solution to controlling my in-line Duct Fan.
