Run whole house fan when cooking?

Can’t seem to find a relevant post. I would like to circulate the whole house fan whenever someone is cooking.

At this time the thermostat turns on the fan. I found an rboy app which runs the fan every hour but need something which can trigger it. Eg. If motion detector near stove comes on or light in kitchen.

There is a popular rule engine called webCoRE that many of us use. Give it a try. Its simple to learn and easy to make Pistons (rules).
