Q: Will this work with samsung smartthings smart home hub 2nd generation?

A definite maybe! I bought one and did get it to work so I bought a second one. I have a 2nd gen Smarthings/ Aerotec hub. I could not get this one to work and spent 2 hours trying various solutions. The linking process could defiantly be improved.

Q: Will this contact sensor work with any tuya zigbee hub?. i need it to work with tuya or smart life app.

I'm using 5 3rd realty switches all via Zigbee hub....should work

Q: is the sensor affected by gravity - meaning - can I angle it, use it upside down, etc? thx!

Not affected by gravity (horizontal or vertical). I have sensors installed on doors and windows. It does not make a difference. They work in either orientation. Hope this helps.

Q: Is this UL 2017 approved?
