I have 2 of these and two with cords, as well as about 50 other sensors, a friend just added a security system by my recommendation and could not believe how intuitive and straight forward the system is. I am an engineer and he is my accountant. I started my system about 3 or 4 years ago and just replaced the first one of my batteries for the first time. A door sensor.

This is tempting because while I can't say much about the hub, the Temp/Humidity sensors show up on the YoLink sensor page for Home Assistant:
https://www.home-assistant.io/int...ns/yolink/

If i can use one of these to turn on my kids' bathroom fan when they shower...it's worth it.

I bought the 3 pack for $60. It's great for tracking basement humidity in different rooms with 24 hour readout in the app. I also use the yolink water sensors with 108 dB alarm.

Does this integrate with Home Assistant?

Meh... I'd be interested if they included an outdoor sensor too. I've had a few of the 'weather station' type home monitors, but they always fail after 2-3 years.

EDIT: Okay, I was confused for a bit. They say it comes with an indoor sensor, but then elsewhere mentions using it outdoors. Seems there's also an outdoors sensor model that's different, but mentioned in this same listing page.

I have 3 Govee sensors/displays around the house and they're great, but they only use bluetooth and they don't integrate well with any other apps. They are accurate with the ability to change calibration which is nice.

Are these Yolink sensors accurate, and can you recalibrate (temp and humidity) manually? Can they integrate with other apps like Home Assistant? The hub acts as a bridge between the sensors and the network?

Door window sensor recommendation for basic needs? On a low budget

I have 3 Govee sensors/displays too! I've become frustrated with the Bluetooth and lack of integration with other smart home systems, so I'm going to give these a try.

I agree that these are awesome. I have 5 as well. The email alert helped me realize last night that I had left the beer fridge open.

YoLink and LoRa protocol is great. You can manually calibrate these. YoLink integrates well with Home Assistant and IFTTT and other big-box platforms. Matter support is coming via software update for Hub 3 & 4 soon. YoLink just launched a new 'local hub' (currently sold out) where you can locally control everything and no cloud connection is required. And the YoLink hubs work with other YoLink components and sensors. YoLink is an additional hub that's actually worth getting.

It Looks Like the Range is 1/4 of a Mile not 4 miles. I would Love a 4 Mile range!
