Heyo

In the summer, I stick box-fans in the windows, pulling in nice cool air and pushing off the use of AC by a couple months

Of course, since these are cheap CT fans, all they have is a rotary dial (0-3), and no real ability to automate.

I decided to add a 3 channel controller on AliExpress

Since my goal is high WAF, everything needs to work via the orinal controls. This allowed me to still use the original rotary dial, while giving me a HA override

Installation was fine, largest annoyance was the fan was original a switched neutral. Once I figured that out, I moved to a switch hot layout, and the tested. Turned on fan… Err, fine.

Threw in shoe glue as adhesive, and wire protection, and put 'er back together

    Interesting idea. I have one that I use with my indoor cycling setup, but I just have it on a Sonoff S31, so I can turn it on (the knob is set to top speed) as I warm up while riding. Then the script that starts the program on the computer also shuts off the fan when the program exits (gotta work in automation somewhere!). I like the idea of being able to control the speed.

      Now I’m imagining a speed-Controlled fan with an automation linking it to the speed of your stationary bike (or a treadmill) to simulate the air you’re moving through. That could be fun.

      Though, I guess you don’t need HA for that and could do it pretty simply with a relay or two.

        There actually is a fan that does that already. It connects to the game and adjusts flow based on your speed.

        Similarly, there’s also a device that adjusts the angle of the bike based on the angle of the hill you’re on at the moment.

        The fan is $320. The other device is $700.

        I just use a box fan and ride flat.

            I mean, I’m a bike person, and I don’t have one, too much money for a fan.

            They also sell a desk that’s $250 or something crazy like that. It is kind of an odd design that leans over the handlebars, though.

            But I work in a shop that regularly sells >$10K bikes, too. My bike is sub-$3K, though.
