Works great with SmartThings, but have had an issue with a different Sonoff sensor going offline several times. These are great because they take AAA batteries. Would recommend for a low cost solution for temperature and humidity readings.

Excellent sensor and very convenient size and takes AAA batteries, which is a huge plus! Reports accurately and seems more consistent than other humidity sensors I own, including Sonoff. Will probably grab a couple more when the price is right.
