Anyone Have A Tamarack Ghost Whole House Attic Fan in Home Assistant?

Hardware

Per the title, trying to make a Tamarack Ghost whole house attic fan (https://www.tamtech.com/wp-content/uploads/2020/09/GH.13-Ghost-Manual.pdf) smart and get it into Home Assistant. The fan comes with an RF remote with 2 buttons. Sequence of buttons is as follows:

Press Button 1 once = Turn on fan on low
Press Button 1 again (when already on) = Turns fan off

If fan is on (after pressing Button 1) you can then press button 2 to go to the higher speed, pressing Button 2 again (while on high speed) turns it back down to low speed.

Just wondering if anyone has this unit and has been able to integrate into Home Assistant and make smart ?

Thanks

So you just need 2 smart relays. When one relay on, other must be off.

You can get an esp32 relay device and have this set to automatically do just this.

Not sure if there are smart switches with multiple positions but that would be another option

Thanks, I’ve never used esp32 relays directly before (other than those that are already fully integrated), is there a specific device you could point me to and any related information that you think I would need ?

Thanks again

I use a Shelly Plus 2PM for my 2-speed attic fan. I chose not to use ESPHome on it (for a couple reasons in this case) but stick with the stock Shelly firmware, which unfortunately doesn’t allow you to interlock the two relays (to keep from accidentally having both relays on). I then created a template fan in HA to control the relays and have it show up as a 2-speed fan.

I’ve had it setup for a year+ and it’s worked quite well. Being able to stay in bed when I happen to wake up early and remotely turn on the attic fan has been pretty nice… :slight_smile:

Sorry No but these are pretty solid so any will work reliably

Just search “esp32 relay” and choose one with 2 relays.

If Poe is possible, “esp32 Poe relay”

If it has more than in relay that is fine. Pretty much all the relays can switch up to 200vac. Look at photo of device and it will show on side. Post here any device your thinking of getting and we can help determine good/bad choice

Thanks so much, I’ll take a look and then post back
