I was struggling to come up with a way to automatically turn on/off a sanitizing UVC light I installed on my HVAC ducting. I had installed the "REKO Lighting R2000 Air Purifier Whole House Uv uvc Light" (purchased on Amazon) but the unit itself has no switch. The way the unit comes, once it's plugged in, it's always on, which shortens the life of the bulbs and wastes electricity. The light itself isn't serving any purpose if it's on while the furnace/AC is not running (since no air circulation means no air is being sanitized). I had looked high and low for a smart vibration sensor that works with Alexa but didn't find much. I finally came across this YoLink unit and purchased it right away. I've been super impressed with Yolink's products, and this vibration sensor certainly didn't disappoint. If you already have a YoLink hub, adding this unit takes about a minute, and can then run off the YoLink App or Alexa (including routine trigger). If you don't have their hub, you'll need another 5 minutes or so to set one up. Once I added the unite to the App, I simply set it on top of my furnace, and now when the furnace turns on, an Alexa routine triggers a smart outlet to turn the UVC light on. When the furnace is not running, the routine triggers the outlet/light to turn off. It could hardly work more perfectly. I'm now dreaming up what else I could with these units.
I have since bought several other YoLink products and they all work wonderfully, and they have some of the easiest setup I've experienced from any smart products. I called their tech support a few times to run a few different scenarios by them, and I always reached a person within 5 minutes. I hope they keep it up.
Yolink products have excellent range and low power consumption due to the type of wireless tech they use (LoRa). Read up on it. YoLink, if you read this, please give your tech support person a raise. I spoke to the same person each time (which is amazing) and he really knew his stuff. Message me if you want to know who it was.
