[Example] Scheduled Exhaust/Air Circulation Fan

#1

This piston is simple, it turns on a fan (plug in module) for exhaust or circulation multiple times per day at scheduled times for a duration each time.

It also updates piston state to display whether the fan is on or off with a spinner icon when running using a variable.


#2

Is there any particular reason your run times vary? Why is one in minutes and the rest in hours? Just curious, Ive already loaded this in prep for adding a fan to our garage. Thank so much for your work.


#3

So yes actually.
We are on a variable cost power plan.

.24/kWh 12-7p M-F
.06/kWh all other times

Hence the short duration at 3pm
The one in minutes is so it will shut off just before noon. (2 minutes before to be exact.
I’m very power conscious. All of my pistons reflect this power management design.
You should see my HVAC cooling piston.

I never really put much thought into our powers tiers. Good to know. Thanks,

I looked for your HVAC piston example, but couldn’t find it. Got a link?
