Can you have more than one temp/humidity sensor in the same house running on the hub and app?

Yes, You can. One Yolink hub can support more than 200 YoLink devices in real test. YoLink Hub covers more than 300 feet indoor and 1000 feet in the open air. Normally one hub is enough for one house. Hope this answer is helpful to you

How often does the sensor check the temp and humidity for automation? Is the sensor only checked after a certain number of minutes?

The sensor updates the app each hour, minimum, but also updates if any of the following occur: At least 0.9 F degree change over a period longer than 1 minute At least 3.6 F degree change within 1 minute At least 5% humidity changes over a period longer than 1 minute The device reaches a pre-set high or low alert level (set by the user) Or the SET button on the device has been pressed

Does this work with smartthings and do i need the yolink hub?

Sorry, YoLink system is not compatible with smarrthings now, YoLink uses LoRa protocol and YoLink Hub is required. Thanks!

I see the YoLink hub is required for all smart features. Is there an alternate way to just connect wifi and monitor from ios without the hub?

No, YoLink hub is required. YoLink smart devices use a special wireless technology based on LoRa, which can offer extreme long range (1000 feet compared to 100 for WiFi, outdoors, line-of-sight) and superior obstruction penetration including concrete and metal, but they do not use your WiFi. They need to wirelessly connect to one of our hubs. Thanks!
