I'm sure it works with the Konke ecosystem, but I ordered it for Smartthings. I was able to pair it to my V2 Hub (please note, that not all Zigbee channels are supported by konke products) I'm working on a device handler and a keychain holder for it, to make it a compact Zigbee remote. If you wonder why: I was not able to find a single keychain remote that works with Smartthings. Results will be available on Thingiverse and GitHub once I have a working prototype.
It says temperature and humidity in product title. Does not have those attributes. Just a button.
