It’s very hard to tell, but I’m guessing the middle one is gpu exhaust. So two outs, one in

Up voted for this. I have a bunch of Yolink products. It all works seamlessly. I’ve got motion lights setup. I have my bathroom exhaust fan set to turn on at a specific humidity level. I’ve got their door locks, garage door opener. Hell, I’ve got the float switch set to tell me when my dogs need more water.

They have so many products and they all work together very well. It truly feels like a smart home now and it’s all the same brand so I don’t have to worry about compatibility problems or using a third party software. I do have them linked to home assistant for the few things I have from other brands. But I can’t reccomend Yolink enough
