Review on Smart Temperature Monitoring Assistant for Sonoff by Chad Judex

The product just doesn't work, the setup is easy but once everything is set up the eWelink app doesn't update new humidity values when they are changed, just keeps the same one Value when you first set it up. I have contacted eWelink several times about this issue, they don't want to fix it. So be aware that this product simply will not work if the humidity changes to activate the device. I do not recommend any product. which eWelink uses.
